Cryptographic functions over raw vectors, including message digests of in-memory data, files and connections, keyed-hash message authentication codes (HMAC), Advanced Encryption Standard (AES) encryption, constant-time comparison and hexadecimal encoding, backed by a bundled and pinned copy of the 'Mbed TLS' project's cryptography library, 'TF-PSA-Crypto' (<https://github.com/Mbed-TLS/TF-PSA-Crypto>). No system cryptographic library, 'Java' or 'Python' is required at install or run time. Algorithm names are matched exactly, and failures are reported as structured conditions. The same primitives, and secure erasure of native buffers, are published to other packages as a static archive and as a registered C interface, so that a package can call them from C without going through R.

| NeedsCompilation: | yes |
| SystemRequirements: | A C99 compiler. No system cryptographic library is used, no CMake, Python or Perl is required, and nothing is downloaded or generated during installation: the backend is built from vendored sources, with an explicit object list in portable make. |
