SSL_CTX_get0_param(3) OpenSSL SSL_CTX_get0_param(3)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)
DESCRIPTIONSSL_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 VALUESSSL_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.
