For nroff, turn off justification. Always turn off hyphenation; it makesway too many mistakes in technical documents.
"NAME"
SSL_get_verify_result - get result of peer certificate verification
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1
#include <openssl/ssl.h>
\&
long SSL_get_verify_result(const SSL *ssl);
.Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBSSL_get_verify_result() returns the result of the verification of the
X509 certificate presented by the peer, if any.
"NOTES"
Header "NOTES" \fBSSL_get_verify_result() can only return one error code while the verification
of a certificate can fail because of many reasons at the same time. Only
the last verification error that occurred during the processing is available
from SSL_get_verify_result().
Sometimes there can be a sequence of errors leading to the verification failure as reported by SSL_get_verify_result(). To get the errors, it is necessary to setup a verify callback via \fBSSL_CTX_set_verify\|(3) or SSL_set_verify\|(3) and retrieve the errors from the error stack there, because once SSL_connect\|(3) returns, these errors may no longer be available.
The verification result is part of the established session and is restored when a session is reused.
"BUGS"
Header "BUGS" If no peer certificate was presented, the returned result code is
X509_V_OK. This is because no verification error occurred, it does however
not indicate success. SSL_get_verify_result() is only useful in connection
with SSL_get_peer_certificate\|(3).
"RETURN VALUES"
Header "RETURN VALUES" The following return values can currently occur:
"X509_V_OK" 4
Item "X509_V_OK" The verification succeeded or no peer certificate was presented.
"Any other value" 4
Item "Any other value" Documented in openssl-verify\|(1).
