NAME

       SSL_CTX_set0_verify_cert_store, SSL_CTX_set1_verify_cert_store, SSL_CTX_set0_chain_cert_store,
       SSL_CTX_set1_chain_cert_store, SSL_set0_verify_cert_store, SSL_set1_verify_cert_store,
       SSL_set0_chain_cert_store, SSL_set1_chain_cert_store - set certificate verification or chain store

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.
