X509_STORE_set_verify_cb_func, X509_STORE_set_verify_cb — set verification callback


 #include <openssl/x509_vfy.h>

 void X509_STORE_set_verify_cb(X509_STORE *st,
                                int (*verify_cb)(int ok, X509_STORE_CTX *ctx));

 void X509_STORE_set_verify_cb_func(X509_STORE *st,
                                int (*verify_cb)(int ok, X509_STORE_CTX *ctx));


X509_STORE_set_verify_cb() sets the verification callback of ctx to verify_cb overwriting any existing callback.

X509_STORE_set_verify_cb_func() also sets the verification callback but it is implemented as a macro.


The verification callback from an X509_STORE is inherited by  the corresponding X509_STORE_CTX structure when it is initialized. This can be used to set the verification callback when the X509_STORE_CTX is  otherwise inaccessible (for example during S/MIME verification).


The macro version of this function was the only one available before  OpenSSL 1.0.0.

Return Values

X509_STORE_set_verify_cb() and X509_STORE_set_verify_cb_func() do not return a value.
