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.
