NAME¶
SSL_CTX_get0_param, SSL_get0_param, SSL_CTX_set1_param, SSL_set1_param - get and
set verification parameters
SYNOPSIS¶
#include <openssl/ssl.h>
X509_VERIFY_PARAM *SSL_CTX_get0_param(SSL_CTX *ctx)
X509_VERIFY_PARAM *SSL_get0_param(SSL *ssl)
int SSL_CTX_set1_param(SSL_CTX *ctx, X509_VERIFY_PARAM *vpm)
int SSL_set1_param(SSL *ssl, X509_VERIFY_PARAM *vpm)
DESCRIPTION¶
SSL_CTX_get0_param() and
SSL_get0_param() retrieve an internal
pointer to the verification parameters for
ctx or
ssl
respectively. The returned pointer must not be freed by the calling
application.
SSL_CTX_set1_param() and
SSL_set1_param() set the verification
parameters to
vpm for
ctx or
ssl.
NOTES¶
Typically parameters are retrieved from an
SSL_CTX or
SSL
structure using
SSL_CTX_get0_param() or
SSL_get0_param() and an
application modifies them to suit its needs: for example to add a hostname
check.
EXAMPLE¶
Check hostname matches "www.foo.com" in peer certificate:
X509_VERIFY_PARAM *vpm = SSL_get0_param(ssl);
X509_VERIFY_PARAM_set1_host(vpm, "www.foo.com", 0);
RETURN VALUES¶
SSL_CTX_get0_param() and
SSL_get0_param() return a pointer to an
X509_VERIFY_PARAM structure.
SSL_CTX_set1_param() and
SSL_set1_param() return 1 for success and
0 for failure.
