To do so the client should call the \&\fBSSL_set_tlsext_status_type()\fR function prior to the start of the handshake. Currently the only supported type is \fBTLSEXT_STATUSTYPE_ocsp\fR. This value should be passed in the \fBtype\fR argument. The client should additionally provide a callback function to decide what to do with the returned \s-1OCSP\s0 response by calling \fBSSL_CTX_set_tlsext_status_cb()\fR. The callback function should determine whether the returned \s-1OCSP\s0 response is acceptable or not. The callback will be passed as an argument the value previously set via a call to \&\fBSSL_CTX_set_tlsext_status_arg()\fR. Note that the callback will not be called in the event of a handshake where session resumption occurs (because there are no Certificates exchanged in such a handshake). .PP The response returned by the server can be obtained via a call to \&\fBSSL_get_tlsext_status_ocsp_resp()\fR. The value \fB*resp\fR will be updated to point to the \s-1OCSP\s0 response data and the return value will be the length of that data. Typically a callback would obtain an \s-1OCSP_RESPONSE\s0 object from this data via a call to the \fBd2i_OCSP_RESPONSE()\fR function. If the server has not provided any response data then \fB*resp\fR will be \s-1NULL\s0 and the return value from \&\fBSSL_get_tlsext_status_ocsp_resp()\fR will be \-1. .PP A server application must also call the \fBSSL_CTX_set_tlsext_status_cb()\fR function if it wants to be able to provide clients with \s-1OCSP\s0 Certificate Status responses. Typically the server callback would obtain the server certificate that is being sent back to the client via a call to \fBSSL_get_certificate()\fR; obtain the \s-1OCSP\s0 response to be sent back; and then set that response data by calling \fBSSL_set_tlsext_status_ocsp_resp()\fR. A pointer to the response data should be provided in the \fBresp\fR argument, and the length of that data should be in the \fBlen\fR argument. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The callback when used on the client side should return a negative value on error; 0 if the response is not acceptable (in which case the handshake will fail) or a positive value if it is acceptable. .PP The callback when used on the server side should return with either \&\s-1SSL_TLSEXT_ERR_OK\s0 (meaning that the \s-1OCSP\s0 response that has been set should be returned), \s-1SSL_TLSEXT_ERR_NOACK\s0 (meaning that an \s-1OCSP\s0 response should not be returned) or \s-1SSL_TLSEXT_ERR_ALERT_FATAL\s0 (meaning that a fatal error has occurred). .PP \&\fBSSL_CTX_set_tlsext_status_cb()\fR, \fBSSL_CTX_set_tlsext_status_arg()\fR, \&\fBSSL_set_tlsext_status_type()\fR and \fBSSL_set_tlsext_status_ocsp_resp()\fR return 0 on error or 1 on success. .PP \&\fBSSL_get_tlsext_status_ocsp_resp()\fR returns the length of the \s-1OCSP\s0 response data or \-1 if there is no \s-1OCSP\s0 response data.
