13 X509_VERIFY_PARAM *SSL_get0_param(SSL *ssl)

15 int SSL_set1_param(SSL *ssl, X509_VERIFY_PARAM *vpm)
16
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
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
31 SSL_CTX_get0_param() and SSL_get0_param() return a pointer to an
32 X509_VERIFY_PARAM structure.
33
34 SSL_CTX_set1_param() and SSL_set1_param() return 1 for success and 0
35 for failure.
36
38 Check hostname matches "www.foo.com" in peer certificate:
39
40 X509_VERIFY_PARAM *vpm = SSL_get0_param(ssl);
41 X509_VERIFY_PARAM_set1_host(vpm, "www.foo.com", 0);
