# SYNOPSIS

     #include <openssl/ssl.h>

     int SSL_CTX_set0_verify_cert_store(SSL_CTX *ctx, X509_STORE *st);
     int SSL_CTX_set1_verify_cert_store(SSL_CTX *ctx, X509_STORE *st);
     int SSL_CTX_set0_chain_cert_store(SSL_CTX *ctx, X509_STORE *st);
     int SSL_CTX_set1_chain_cert_store(SSL_CTX *ctx, X509_STORE *st);

     int SSL_set0_verify_cert_store(SSL *ctx, X509_STORE *st);
     int SSL_set1_verify_cert_store(SSL *ctx, X509_STORE *st);
     int SSL_set0_chain_cert_store(SSL *ctx, X509_STORE *st);
     int SSL_set1_chain_cert_store(SSL *ctx, X509_STORE *st);

# DESCRIPTION

SSL_CTX_set0_verify_cert_store() and SSL_CTX_set1_verify_cert_store() set the certificate store used for certificate verification to st.

SSL_CTX_set0_chain_cert_store() and SSL_CTX_set1_chain_cert_store() set the certificate store used for certificate chain building to st.

SSL_set0_verify_cert_store(), SSL_set1_verify_cert_store(), SSL_set0_chain_cert_store() and SSL_set1_chain_cert_store() are similar except they apply to SSL structure ssl.

All these functions are implemented as macros. Those containing a 1 increment the reference count of the supplied store so it must be freed at some point after the operation. Those containing a 0 do not increment reference counts and the supplied store MUST NOT be freed after the operation.

# NOTES

The stores pointers associated with an SSL_CTX structure are copied to any SSL structures when SSL_new() is called. As a result SSL structures will not be affected if the parent SSL_CTX store pointer is set to a new value.

The verification store is used to verify the certificate chain sent by the peer: that is an SSL/TLS client will use the verification store to verify the server's certificate chain and a SSL/TLS server will use it to verify any client certificate chain.

The chain store is used to build the certificate chain.

If the mode SSL_MODE_NO_AUTO_CHAIN is set or a certificate chain is configured already (for example using the functions such as SSL_CTX_add1_chain_cert(3) or SSL_CTX_add_extra_chain_cert(3)) then automatic chain building is disabled.

If the mode SSL_MODE_NO_AUTO_CHAIN is set then automatic chain building is disabled.

If the chain or the verification store is not set then the store associated with the parent SSL_CTX is used instead to retain compatibility with previous versions of OpenSSL.

# RETURN VALUES

All these functions return 1 for success and 0 for failure.
