OpenSSL SSL_CTX_set_cert_store(3openssl) NAME SSL_CTX_set_cert_store, SSL_CTX_get_cert_store - manipulate X509 certificate verification storage SYNOPSIS #include <openssl/ssl.h> void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store); X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx); DESCRIPTION SSL_CTX_set_cert_store() sets/replaces the certificate verification storage of ctx to/with store. 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. ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+--------------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+--------------------------+ |Availability | library/security/openssl | +---------------+--------------------------+ |Stability | Pass-through uncommitted | +---------------+--------------------------+ NOTES In order to verify the certificates presented by the peer, trusted CA certificates must be accessed. These CA certificates are made available via lookup methods, handled inside the X509_STORE. From the X509_STORE the X509_STORE_CTX used when verifying certificates is created. 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.

RESTRICTIONS The X509_STORE structure used by an SSL_CTX is used for verifying peer certificates and building certificate chains, it is also shared by every child SSL structure. Applications wanting finer control can use functions such as SSL_CTX_set1_verify_cert_store() instead. RETURN VALUES SSL_CTX_set_cert_store() does not return diagnostic output. SSL_CTX_get_cert_store() returns the current setting. SEE ALSO ssl(3), SSL_CTX_load_verify_locations(3), SSL_CTX_set_verify(3) 1.0.2ze 2022-05-03 SSL_CTX_set_cert_store(3openssl)
