NAME

6       SSL_CTX_get0_param, SSL_get0_param, SSL_CTX_set1_param, SSL_set1_param
7       - get and set verification parameters
8

SYNOPSIS

10        #include <openssl/ssl.h>
11
12        X509_VERIFY_PARAM *SSL_CTX_get0_param(SSL_CTX *ctx)
13        X509_VERIFY_PARAM *SSL_get0_param(SSL *ssl)
14        int SSL_CTX_set1_param(SSL_CTX *ctx, X509_VERIFY_PARAM *vpm)
15        int SSL_set1_param(SSL *ssl, X509_VERIFY_PARAM *vpm)
16

DESCRIPTION

18       SSL_CTX_get0_param() and SSL_get0_param() retrieve an internal pointer
19       to the verification parameters for ctx or ssl respectively. The
20       returned pointer must not be freed by the calling application.
21
22       SSL_CTX_set1_param() and SSL_set1_param() set the verification
23       parameters to vpm for ctx or ssl.
24

NOTES

26       Typically parameters are retrieved from an SSL_CTX or SSL structure
27       using SSL_CTX_get0_param() or SSL_get0_param() and an application
28       modifies them to suit its needs: for example to add a hostname check.
29

EXAMPLE

31       Check hostname matches "www.foo.com" in peer certificate:
32
33        X509_VERIFY_PARAM *vpm = SSL_get0_param(ssl);
34        X509_VERIFY_PARAM_set1_host(vpm, "www.foo.com", 0);
35

RETURN VALUES

37       SSL_CTX_get0_param() and SSL_get0_param() return a pointer to an
38       X509_VERIFY_PARAM structure.
39
40       SSL_CTX_set1_param() and SSL_set1_param() return 1 for success and 0
41       for failure.
