1. Introduction

This document defines three YANG 1.1 [RFC7950] modules: the first defines features and groupings common to both TLS clients and TLS servers, the second defines a grouping for a generic TLS client, and the third defines a grouping for a generic TLS server.

Any version of TLS may be configured. TLS 1.0 [RFC2246] and TLS 1.1 [RFC4346] are historic and hence the YANG "feature" statements enabling them are marked "status obsolete". TLS 1.2 [RFC5246] is obsoleted by TLS 1.3 [RFC8446] but still in common use, and hence its "feature" statement is marked "status deprecated". All the feature statements for 1.0, 1.1, and 1.3 have "description" statements stating that it is NOT RECOMMENDED to enable obsolete protocol versions.

It is intended that the YANG groupings will be used by applications needing to configure TLS client and server protocol stacks. For instance, these groupings are used to help define the data model for HTTPS [RFC2818] and NETCONF over TLS [RFC7589] based clients and servers in [I-D.ietf-netconf-http-client-server] and [I-D.ietf-netconf-netconf-client-server] respectively.

The client and server YANG modules in this document each define one grouping, which is focused on just TLS-specific configuration, and specifically avoids any transport-level configuration, such as what ports to listen-on or connect-to. This affords applications the opportunity to define their own strategy for how the underlying TCP connection is established. For instance, applications supporting NETCONF Call Home [RFC8071] could use the "tls-server-grouping" grouping for the TLS parts it provides, while adding data nodes for the TCP-level call-home configuration.

1.1. Relation to other RFCs

This document presents one or more YANG modules [RFC7950] that are part of a collection of RFCs that work together to, ultimately, enable the configuration of the clients and servers of both the NETCONF [RFC6241] and RESTCONF [RFC8040] protocols.

The modules have been defined in a modular fashion to enable their use by other efforts, some of which are known to be in progress at the time of this writing, with many more expected to be defined in time.

The normative dependency relationship between the various RFCs in the collection is presented in the below diagram. The labels in the diagram represent the primary purpose provided by each RFC. Hyperlinks to each RFC are provided below the diagram.

1.2. Specification Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

1.3. Adherence to the NMDA

This document is compliant with the Network Management Datastore Architecture (NMDA) [RFC8342]. For instance, as described in [I-D.ietf-netconf-trust-anchors] and [I-D.ietf-netconf-keystore], trust anchors and keys installed during manufacturing are expected to appear in <operational>.

1.4. Conventions

Various examples used in this document use a placeholder value for binary data that has been base64 encoded (e.g., "BASE64VALUE="). This placeholder value is used as real base64 encoded structures are often many lines long and hence distracting to the example being presented.

2. The "ietf-tls-common" Module

The TLS common model presented in this section contains features and groupings common to both TLS clients and TLS servers. The "hello-params-grouping" grouping can be used to configure the list of TLS algorithms permitted by the TLS client or TLS server. The lists of algorithms are ordered such that, if multiple algorithms are permitted by the client, the algorithm that appears first in its list that is also permitted by the server is used for the TLS transport layer connection. The ability to restrict the algorithms allowed is provided in this grouping for TLS clients and TLS servers that are capable of doing so and may serve to make TLS clients and TLS servers compliant with local security policies. This model supports both TLS 1.2 [RFC5246] and TLS 1.3 [RFC8446].

Thus, in order to support both TLS1.2 and TLS1.3, the cipher-suites part of the "hello-params-grouping" grouping should include three parameters for configuring its permitted TLS algorithms, which are: TLS Cipher Suites, TLS SignatureScheme, TLS Supported Groups. Note that TLS1.2 only uses TLS Cipher Suites.

2.1. Data Model Overview

This section provides an overview of the "ietf-tls-common" module in terms of its features, identities, and groupings.

2.1.1. Features

The following diagram lists all the "feature" statements defined in the "ietf-tls-common" module:

Features:
  +-- tls10
  +-- tls11
  +-- tls12
  +-- tls13
  +-- hello-params
  +-- public-key-generation

2.1.2. Identities

The following diagram illustrates the relationship amongst the "identity" statements defined in the "ietf-tls-common" module:

Identities:
  +-- tls-version-base
     +-- tls10
     +-- tls11
     +-- tls12
     +-- tls13

Comments:

  • The diagram shows that there are two base identities.
  • One base identity is used to specific TLS versions, while the other is used to specify cipher-suites.
  • These base identities are "abstract", in the object oriented programming sense, in that they only define a "class" of things, rather than a specific thing.

2.1.3. Groupings

The "ietf-tls-common" module defines the following "grouping" statement:

  • hello-params-grouping

This grouping is presented in the following subsection.

2.1.3.1. The "hello-params-grouping" Grouping

The following tree diagram [RFC8340] illustrates the "hello-params-grouping" grouping:

  grouping hello-params-grouping:
    +-- tls-versions
    |  +-- tls-version*   identityref
    +-- cipher-suites
       +-- cipher-suite*   identityref

Comments:

  • This grouping is used by both the "tls-client-grouping" and the "tls-server-grouping" groupings defined in Section 3.1.2.1 and Section 4.1.2.1, respectively.
  • This grouping enables client and server configurations to specify the TLS versions and cipher suites that are to be used when establishing TLS sessions.
  • The "cipher-suites" list is "ordered-by user".

2.1.4. Protocol-accessible Nodes

The following tree diagram [RFC8340] lists all the protocol-accessible nodes defined in the "ietf-tls-common" module, without expanding the "grouping" statements:

module: ietf-tls-common

  rpcs:
    +---x generate-public-key {public-key-generation}?
       +---w input
       |  +---w algorithm
       |  |       tlscsa:cipher-suite-algorithm-ref
       |  +---w bits?                 uint16
       |  +---w (private-key-encoding)?
       |     +--:(cleartext)
       |     |  +---w cleartext?      empty
       |     +--:(encrypt) {ct:private-key-encryption}?
       |     |  +---w encrypt-with
       |     |     +---w ks:encrypted-by-choice-grouping
       |     +--:(hide) {ct:hidden-keys}?
       |        +---w hide?           empty
       +--ro output
          +---u ct:asymmetric-key-pair-grouping

The following tree diagram [RFC8340] lists all the protocol-accessible nodes defined in the "ietf-tls-common" module, with all "grouping" statements expanded, enabling the module's full structure to be seen:

3. The "ietf-tls-client" Module

This section defines a YANG 1.1 [RFC7950] module called "ietf-tls-client". A high-level overview of the module is provided in Section 3.1. Examples illustrating the module's use are provided in Examples (Section 3.2). The YANG module itself is defined in Section 3.3.

3.1. Data Model Overview

This section provides an overview of the "ietf-tls-client" module in terms of its features and groupings.

3.1.1. Features

The following diagram lists all the "feature" statements defined in the "ietf-tls-client" module:

Features:
  +-- tls-client-keepalives
  +-- client-ident-x509-cert
  +-- client-ident-raw-public-key
  +-- client-ident-psk
  +-- server-auth-x509-cert
  +-- server-auth-raw-public-key
  +-- server-auth-psk

3.1.2. Groupings

The "ietf-tls-client" module defines the following "grouping" statement:

  • tls-client-grouping

This grouping is presented in the following subsection.

3.1.2.1. The "tls-client-grouping" Grouping

The following tree diagram [RFC8340] illustrates the "tls-client-grouping" grouping:

=============== NOTE: '\' line wrapping per RFC 8792 ================

    +-- client-identity!
    |  +-- (auth-type)
    |     +--:(certificate) {client-ident-x509-cert}?

    |           |       uint16
    |           +-- target-kdf?
    |                   uint16
    +-- server-authentication
    |  +-- ca-certs! {server-auth-x509-cert}?
    |  |  +---u ts:local-or-truststore-certs-grouping
    |  +-- ee-certs! {server-auth-x509-cert}?
    |  |  +---u ts:local-or-truststore-certs-grouping
    |  +-- raw-public-keys! {server-auth-raw-public-key}?
    |  |  +---u ts:local-or-truststore-public-keys-grouping
    |  +-- tls12-psks?        empty {server-auth-tls12-psk}?
    |  +-- tls13-epsks?       empty {server-auth-tls13-epsk}?
    +-- hello-params {tlscmn:hello-params}?
    |  +---u tlscmn:hello-params-grouping
    +-- keepalives {tls-client-keepalives}?
       +-- peer-allowed-to-send?   empty
       +-- test-peer-aliveness!
          +-- max-wait?       uint16
          +-- max-attempts?   uint8

Comments:

  • The "client-identity" node, which is optionally configured (as client authentication MAY occur at a higher protocol layer), configures identity credentials, each enabled by a "feature" statement defined in Section 3.1.1.
  • The "server-authentication" node configures trust anchors for authenticating the TLS server, with each option enabled by a "feature" statement.
  • The "hello-params" node, which must be enabled by a feature, configures parameters for the TLS sessions established by this configuration.
  • The "keepalives" node, which must be enabled by a feature, configures a "presence" container for testing the aliveness of the TLS server. The aliveness-test occurs at the TLS protocol layer.

  • For the referenced grouping statement(s):

3.1.3. Protocol-accessible Nodes

The "ietf-tls-client" module defines only "grouping" statements that are used by other modules to instantiate protocol-accessible nodes.

3.2. Example Usage

This section presents two examples showing the "tls-client-grouping" grouping populated with some data. These examples are effectively the same except the first configures the client identity using a local key while the second uses a key configured in a keystore. Both examples are consistent with the examples presented in Section 2 of [I-D.ietf-netconf-trust-anchors] and Section 3.2 of [I-D.ietf-netconf-keystore].

The following configuration example uses local-definitions for the client identity and server authentication:

4. The "ietf-tls-server" Module

This section defines a YANG 1.1 module called "ietf-tls-server". A high-level overview of the module is provided in Section 4.1. Examples illustrating the module's use are provided in Examples (Section 4.2). The YANG module itself is defined in Section 4.3.

4.1. Data Model Overview

This section provides an overview of the "ietf-tls-server" module in terms of its features and groupings.

4.1.1. Features

The following diagram lists all the "feature" statements defined in the "ietf-tls-server" module:

Features:
  +-- tls-server-keepalives
  +-- server-ident-x509-cert
  +-- server-ident-raw-public-key
  +-- server-ident-psk
  +-- client-auth-supported
  +-- client-auth-x509-cert
  +-- client-auth-raw-public-key
  +-- client-auth-psk

4.1.2. Groupings

The "ietf-tls-server" module defines the following "grouping" statement:

  • tls-server-grouping

This grouping is presented in the following subsection.

4.1.2.1. The "tls-server-grouping" Grouping

The following tree diagram [RFC8340] illustrates the "tls-server-grouping" grouping:

Comments:

  • The "server-identity" node configures identity credentials, each of which is enabled by a "feature".
  • The "client-authentication" node, which is optionally configured (as client authentication MAY occur at a higher protocol layer), configures trust anchors for authenticating the TLS client, with each option enabled by a "feature" statement.
  • The "hello-params" node, which must be enabled by a feature, configures parameters for the TLS sessions established by this configuration.
  • The "keepalives" node, which must be enabled by a feature, configures a flag enabling the TLS client to test the aliveness of the TLS server, as well as a "presence" container for testing the aliveness of the TLSi client. The aliveness-tests occurs at the TLS protocol layer.

  • For the referenced grouping statement(s):

4.1.3. Protocol-accessible Nodes

The "ietf-tls-server" module defines only "grouping" statements that are used by other modules to instantiate protocol-accessible nodes.

4.2. Example Usage

This section presents two examples showing the "tls-server-grouping" grouping populated with some data. These examples are effectively the same except the first configures the server identity using a local key while the second uses a key configured in a keystore. Both examples are consistent with the examples presented in Section 2 of [I-D.ietf-netconf-trust-anchors] and Section 3.2 of [I-D.ietf-netconf-keystore].

The following configuration example uses local-definitions for the server identity and client authentication:

5. Security Considerations

5.1. The "iana-tls-cipher-suite-algs" Module

The "iana-tls-cipher-suite-algs" YANG module defines a data model that is designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication.

The NETCONF access control model (NACM) [RFC8341] provides the means to restrict access for particular users to a pre-configured subset of all available protocol operations and content.

This YANG module defines YANG identities, for a public IANA-maintained registry, and a single protocol-accessible read-only node for the subset of those identities supported by a server.

YANG identities are not security-sensitive, as they are statically defined in the publicly-accessible YANG module.

The protocol-accessible read-only node for the algorithms supported by a server is mildly sensitive, but not to the extent that special NACM annotations are needed to prevent read-access to regular authenticated administrators.

This module does not define any writable-nodes, RPCs, actions, or notifications, and thus the security consideration for such is not provided here.

5.2. The "ietf-tls-common" YANG Module

The "ietf-tls-common" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication.

The NETCONF access control model (NACM) [RFC8341] provides the means to restrict access for particular users to a pre-configured subset of all available protocol operations and content.

Since the module in this document only define groupings, these considerations are primarily for the designers of other modules that use these groupings.

None of the readable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-all" extension has not been set for any data nodes defined in this module.

None of the writable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-write" extension has not been set for any data nodes defined in this module.

This module does not define any RPCs, actions, or notifications, and thus the security consideration for such is not provided here.

5.3. The "ietf-tls-client" YANG Module

The "ietf-tls-client" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication.

The NETCONF access control model (NACM) [RFC8341] provides the means to restrict access for particular users to a pre-configured subset of all available protocol operations and content.

Since the module in this document only define groupings, these considerations are primarily for the designers of other modules that use these groupings.

None of the readable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-all" extension has not been set for any data nodes defined in this module.

All the writable data nodes defined by this module may be considered sensitive or vulnerable in some network environments. For instance, any modification to a key or reference to a key may dramatically alter the implemented security policy. For this reason, the NACM extension "default-deny-write" has been set for all data nodes defined in this module.

This module does not define any RPCs, actions, or notifications, and thus the security consideration for such is not provided here.

5.4. The "ietf-tls-server" YANG Module

The "ietf-tls-server" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication.

This module does not define any RPCs, actions, or notifications, and thus the security consideration for such is not provided here.

6. IANA Considerations

6.1. The "IETF XML" Registry

This document registers four URIs in the "ns" subregistry of the IETF XML Registry [RFC3688]. Following the format in [RFC3688], the following registrations are requested:

URI: urn:ietf:params:xml:ns:yang:iana-tls-cipher-suite-algs
Registrant Contact: IANA
XML: N/A, the requested URI is an XML namespace.

URI: urn:ietf:params:xml:ns:yang:ietf-tls-common
Registrant Contact: The IESG
XML: N/A, the requested URI is an XML namespace.

URI: urn:ietf:params:xml:ns:yang:ietf-tls-client
Registrant Contact: The IESG
XML: N/A, the requested URI is an XML namespace.

URI: urn:ietf:params:xml:ns:yang:ietf-tls-server
Registrant Contact: The IESG
XML: N/A, the requested URI is an XML namespace.

6.2. The "YANG Module Names" Registry

This document registers four YANG modules in the YANG Module Names registry [RFC6020]. Following the format in [RFC6020], the following registrations are requested:

name:         iana-tls-cipher-suite-algs
namespace:    urn:ietf:params:xml:ns:yang:iana-tls-cipher-suite-algs
prefix:       tlscsa

name:         ietf-tls-client
namespace:    urn:ietf:params:xml:ns:yang:ietf-tls-client
prefix:       tlsc
reference:    RFC FFFF

name:         ietf-tls-server
namespace:    urn:ietf:params:xml:ns:yang:ietf-tls-server
prefix:       tlss
reference:    RFC FFFF

6.3. The "iana-tls-cipher-suite-algs" Module

IANA is requested to maintain a YANG module called "iana-tls-cipher-suite-algs" that shadows the "TLS Cipher Suites" sub-registry of the "Transport Layer Security (TLS) Parameters" registry [IANA-CIPHER-ALGS].

This registry defines a YANG identity for each cipher suite algorithm, and a "base" identity from which all of the other identities are derived.

An initial version of this module can be found in Appendix A.1.

Appendix A. YANG Modules for IANA

The module contained in this section was generated by scripts using the contents of the associated sub-registry as they existed on June 16th, 2022.

A.1. Initial Module for the "TLS Cipher Suites" Registry

A.1.1. Data Model Overview

This section provides an overview of the "iana-tls-cipher-suite-algs" module in terms of its identities and protocol-accessible nodes.

A.1.1.1. Identities

The following diagram lists the base "identity" statements defined in the module, of which there is just one, and illustrates that all the derived identity statements are generated from the associated IANA-maintained registry [IANA-CIPHER-ALGS].

Identities:
  +-- cipher-suite-alg-base
    +-- <identity-name from IANA registry>
A.1.1.2. Typedefs

The following diagram illustrates the "typedef" statements defined in the "iana-tls-cipher-suite-algs" module:

Typedefs:
  identityref
    +-- cipher-suite-algorithm-ref

Comments:

  • The typedef defined in the "iana-tls-cipher-suite-algs" module extends the "identityref" type defined in [RFC7950].
A.1.1.3. Protocol-accessible Nodes

The following tree diagram [RFC8340] lists all the protocol-accessible nodes defined in the "iana-tls-cipher-suite-alg" module:

module: iana-tls-cipher-suite-algs
  +--ro supported-algorithms
     +--ro supported-algorithm*   cipher-suite-algorithm-ref

Comments:

  • Protocol-accessible nodes are those nodes that are accessible when the module is "implemented", as described in Section 5.6.5 of [RFC7950].

A.1.2. Example Usage

The following example illustrates operational state data indicating the TLS cipher suite algorithms supported by the server:

Appendix B. Change Log

This section is to be removed before publishing as an RFC.

B.1. 00 to 01

  • Noted that '0.0.0.0' and '::' might have special meanings.
  • Renamed "keychain" to "keystore".

B.2. 01 to 02

  • Removed the groupings containing transport-level configuration. Now modules contain only the transport-independent groupings.
  • Filled in previously incomplete 'ietf-tls-client' module.
  • Added cipher suites for various algorithms into new 'ietf-tls-common' module.

B.3. 02 to 03

  • Added a 'must' statement to container 'server-auth' asserting that at least one of the various auth mechanisms must be specified.
  • Fixed description statement for leaf 'trusted-ca-certs'.

B.4. 03 to 04

  • Updated title to "YANG Groupings for TLS Clients and TLS Servers"
  • Updated leafref paths to point to new keystore path
  • Changed the YANG prefix for ietf-tls-common from 'tlscom' to 'tlscmn'.
  • Added TLS protocol verions 1.0 and 1.1.
  • Made author lists consistent
  • Now tree diagrams reference ietf-netmod-yang-tree-diagrams
  • Updated YANG to use typedefs around leafrefs to common keystore paths
  • Now inlines key and certificates (no longer a leafref to keystore)

B.5. 04 to 05

  • Merged changes from co-author.

B.6. 05 to 06

  • Updated to use trust anchors from trust-anchors draft (was keystore draft)
  • Now Uses new keystore grouping enabling asymmetric key to be either locally defined or a reference to the keystore.

B.7. 06 to 07

  • factored the tls-[client|server]-groupings into more reusable groupings.
  • added if-feature statements for the new "x509-certificates" feature defined in draft-ietf-netconf-trust-anchors.

B.8. 07 to 08

  • Added a number of compatibility matrices to Section 5 (thanks Frank!)
  • Clarified that any configured "cipher-suite" values need to be compatible with the configured private key.

B.9. 08 to 09

  • Updated examples to reflect update to groupings defined in the keystore draft.
  • Add TLS keepalives features and groupings.
  • Prefixed top-level TLS grouping nodes with 'tls-' and support mashups.
  • Updated copyright date, boilerplate template, affiliation, and folding algorithm.

B.10. 09 to 10

  • Reformatted the YANG modules.

B.11. 10 to 11

  • Collapsed all the inner groupings into the top-level grouping.
  • Added a top-level "demux container" inside the top-level grouping.
  • Added NACM statements and updated the Security Considerations section.
  • Added "presence" statements on the "keepalive" containers, as was needed to address a validation error that appeared after adding the "must" statements into the NETCONF/RESTCONF client/server modules.
  • Updated the boilerplate text in module-level "description" statement to match copyeditor convention.

B.12. 11 to 12

  • In server model, made 'client-authentication' a 'presence' node indicating that the server supports client authentication.
  • In the server model, added a 'required-or-optional' choice to 'client-authentication' to better support protocols such as RESTCONF.
  • In the server model, added a 'local-or-external' choice to 'client-authentication' to better support consuming data models that prefer to keep client auth with client definitions than in a model principally concerned with the "transport".
  • In both models, removed the "demux containers", floating the nacm:default-deny-write to each descendant node, and adding a note to model designers regarding the potential need to add their own demux containers.
  • Fixed a couple references (section 2 --> section 3)

B.13. 12 to 13

  • Updated to reflect changes in trust-anchors drafts (e.g., s/trust-anchors/truststore/g + s/pinned.//)

B.14. 12 to 13

  • Removed 'container' under 'client-identity' to match server model.
  • Updated examples to reflect change grouping in keystore module.

B.15. 13 to 14

  • Removed the "certificate" container from "client-identity" in the ietf-tls-client module.
  • Updated examples to reflect ietf-crypto-types change (e.g., identities --> enumerations)

B.16. 14 to 15

  • Updated "server-authentication" and "client-authentication" nodes from being a leaf of type "ts:certificates-ref" to a container that uses "ts:local-or-truststore-certs-grouping".

B.17. 15 to 16

  • Removed unnecessary if-feature statements in the -client and -server modules.
  • Cleaned up some description statements in the -client and -server modules.
  • Fixed a canonical ordering issue in ietf-tls-common detected by new pyang.

B.18. 16 to 17

  • Removed choice local-or-external by removing the 'external' case and flattening the 'local' case and adding a "client-auth-supported" feature.
  • Removed choice required-or-optional.
  • Updated examples to include the "*-key-format" nodes.
  • Augmented-in "must" expressions ensuring that locally-defined public-key-format are "ct:tls-public-key-format" (must expr for ref'ed keys are TBD).

B.19. 17 to 18

  • Removed the unused "external-client-auth-supported" feature.
  • Made client-indentity optional, as there may be over-the-top auth instead.
  • Added augment to uses of local-or-keystore-symmetric-key-grouping for a psk "id" node.
  • Added missing presence container "psks" to ietf-tls-server's "client-authentication" container.
  • Updated examples to reflect new "bag" addition to truststore.
  • Removed feature-limited caseless 'case' statements to improve tree diagram rendering.
  • Refined truststore/keystore groupings to ensure the key formats "must" be particular values.
  • Switched to using truststore's new "public-key" bag (instead of separate "ssh-public-key" and "raw-public-key" bags).
  • Updated client/server examples to cover ALL cases (local/ref x cert/raw-key/psk).

B.20. 18 to 19

  • Updated the "keepalives" containers in part to address Michal Vasko's request to align with RFC 8071, and in part to better align to RFC 6520.
  • Removed algorithm-mapping tables from the "TLS Common Model" section
  • Removed the 'algorithm' node from the examples.
  • Renamed both "client-certs" and "server-certs" to "ee-certs"
  • Added a "Note to Reviewers" note to first page.

B.21. 19 to 20

  • Modified the 'must' expression in the "ietf-tls-client:server-authention" node to cover the "raw-public-keys" and "psks" nodes also.
  • Added a "must 'ca-certs or ee-certs or raw-public-keys or psks'" statement to the ietf-tls-server:client-authentication" node.
  • Added "mandatory true" to "choice auth-type" and a "presence" statement to its ancestor.
  • Expanded "Data Model Overview section(s) [remove "wall" of tree diagrams].
  • Moved the "ietf-tls-common" module section to proceed the other two module sections.
  • Updated the Security Considerations section.

B.22. 20 to 21

  • Updated examples to reflect new "cleartext-" prefix in the crypto-types draft.

B.23. 21 to 22

  • In both the "client-authentication" and "server-authentication" subtrees, replaced the "psks" node from being a P-container to a leaf of type "empty".
  • Cleaned up examples (e.g., removed FIXMEs)
  • Fixed issues found by the SecDir review of the "keystore" draft.
  • Updated the "psk" sections in the "ietf-tls-client" and "ietf-tls-server" modules to more correctly reflect RFC 4279.

B.24. 22 to 23

  • Addressed comments raised by YANG Doctor in the ct/ts/ks drafts.

B.25. 23 to 24

  • Added missing reference to "FIPS PUB 180-4".
