The certificate which is returned by \&\fBSSL_get_certificate()\fR is determined as follows: .IP "\(bu" 4 If it is called before certificate selection has occurred, it returns the most recently added certificate, or \s-1NULL\s0 if no certificate has been added. .IP "\(bu" 4 After certificate selection has occurred, it returns the certificate which was selected during the handshake, or \s-1NULL\s0 if no certificate was selected (for example, on a client where no client certificate is in use). .PP Certificate selection occurs during the handshake; therefore, the value returned by \fBSSL_get_certificate()\fR during any callback made during the handshake process will depend on whether that callback is made before or after certificate selection occurs. .PP A specific use for \fBSSL_get_certificate()\fR is inside a callback set via a call to \&\fBSSL_CTX_set_tlsext_status_cb\fR\|(3). This callback occurs after certificate selection, where it can be used to examine a server's chosen certificate, for example for the purpose of identifying a certificate's \s-1OCSP\s0 responder \s-1URL\s0 so that an \s-1OCSP\s0 response can be obtained. .PP \&\fBSSL_get_privatekey()\fR returns a pointer to the \fB\s-1EVP_PKEY\s0\fR object corresponding to the certificate returned by \fBSSL_get_certificate()\fR, if any. .SH "RETURN VALUES" .IX Header "RETURN VALUES" These functions return pointers to their respective objects, or \s-1NULL\s0 if no such object is available. Returned objects are owned by the \s-1SSL\s0 object and should not be freed by users of these functions. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_CTX_set_tlsext_status_cb\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2022 The OpenSSL Project Authors.
