SSL_CTX_SET_CERT_STOR... BSD Library Functions Manual SSL_CTX_SET_CERT_STOR...NAME
SSL_CTX_set_cert_store, SSL_CTX_get_cert_store — manipulate X509 certifi‐
cate 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);
DESCRIPTIONSSL_CTX_set_cert_store() setsthe verification storage of ctx to or
replaces it with store. If another X509_STORE object is currently set in
ctx, it will be X509_STORE_free(3)ed.
SSL_CTX_get_cert_store() returns a pointer to the current certificate
verification storage.
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 veri‐
fication 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 docu‐
mentation about the X509_STORE object and its handling becomes available.
RETURN VALUESSSL_CTX_set_cert_store() does not return diagnostic output.
SSL_CTX_get_cert_store() returns the current setting.
