#include <openssl/ssl.h> void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store); void SSL_CTX_set1_cert_store(SSL_CTX *ctx, X509_STORE *store); X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx);
SSL_CTX_set1_cert_store() sets/replaces the certificate verification storage of ctx to/with store. The store's reference count is incremented. If another X509_STORE object is currently set in ctx, it will be X509_STORE_free()ed.
SSL_CTX_get_cert_store() returns a pointer to the current certificate verification storage.
Typically the trusted certificate store is handled indirectly via using SSL_CTX_load_verify_locations(3). Using the SSL_CTX_set_cert_store() and SSL_CTX_get_cert_store() functions it is possible to manipulate the X509_STORE object beyond the SSL_CTX_load_verify_locations(3) call.
Currently no detailed documentation on how to use the X509_STORE object is available. Not all members of the X509_STORE are used when the verification takes place. So will e.g. the verify_callback() be overridden with the verify_callback() set via the SSL_CTX_set_verify(3) family of functions. This document must therefore be updated when documentation about the X509_STORE object and its handling becomes available.
SSL_CTX_set_cert_store() does not increment the store's reference count, so it should not be used to assign an X509_STORE that is owned by another SSL_CTX.
To share X509_STOREs between two SSL_CTXs, use SSL_CTX_get_cert_store() to get the X509_STORE from the first SSL_CTX, and then use SSL_CTX_set1_cert_store() to assign to the second SSL_CTX and increment the reference count of the X509_STORE.
SSL_CTX_set1_cert_store() does not return diagnostic output.
SSL_CTX_get_cert_store() returns the current setting.
