SSL_CTX_SET_CERT_STORE(3) Library Functions Manual SSL_CTX_SET_CERT_STORE(3)

NAME

SSL_CTX_set_cert_store, SSL_CTX_get_cert_storemanipulate 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 the verification storage of ctx to or replaces it with store. If another X509_STORE object is currently set in ctx, it will be freed.
SSL_CTX_get_cert_store() returns a pointer to the current certificate verification storage.
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, for example, 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.

RETURN VALUES

SSL_CTX_get_cert_store() returns the current setting.
