API function

## NAME

gnutls\_ocsp\_req\_add\_cert - API function

## SYNOPSIS

**#include \<gnutls/ocsp.h\>**

**int gnutls\_ocsp\_req\_add\_cert(gnutls\_ocsp\_req\_t** *req***, gnutls\_digest\_algorithm\_t** *digest***, gnutls\_x509\_crt\_t** *issuer***, gnutls\_x509\_crt\_t** *cert***);**

## ARGUMENTS

- gnutls\_ocsp\_req\_t req

  should contain a **gnutls\_ocsp\_req\_t** type

- gnutls\_digest\_algorithm\_t digest

  hash algorithm, a **gnutls\_digest\_algorithm\_t** value

- gnutls\_x509\_crt\_t issuer

  issuer of  *subject* certificate

- gnutls\_x509\_crt\_t cert

  certificate to request status for

## DESCRIPTION

This function will add another request to the OCSP request for a particular certificate.  The issuer name hash, issuer key hash, and serial number fields is populated as follows.  The issuer name and the serial number is taken from  *cert* .  The issuer key is taken from  *issuer* .  The hashed values will be hashed using the  *digest* algorithm, normally **GNUTLS\_DIG\_SHA1**.

## RETURNS

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error code is returned.
