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 incre-
       ment 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 asso-
       ciated 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.
