# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

**#include &lt;gnutls/ocsp.h&gt;**

**int gnutls\_ocsp\_req\_add\_cert\_id(gnutls\_ocsp\_req\_t req, gnutls\_digest\_algorithm\_t digest, const gnutls\_datum\_t * issuer\_name\_hash, const gnutls\_datum\_t * issuer\_key\_hash, const gnutls\_datum\_t * serial\_number);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_ocsp\_req\_t req](#gnutls_ocsp_req_t)

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

[gnutls\_digest\_algorithm\_t digest](#gnutls_digest_algorithm_t)

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

[const gnutls\_datum\_t * issuer\_name\_hash](#const)

hash of issuer's DN

[const gnutls\_datum\_t * issuer\_key\_hash](#const~2)

hash of issuer's public key

[const gnutls\_datum\_t * serial\_number](#const~3)

serial number of certificate to check

# [DESCRIPTION](#DESCRIPTION)

This function will add another request to the OCSP request for a particular certificate having the issuer name hash of  
*issuer\_name\_hash* and issuer key hash of *issuer\_key\_hash* (both hashed using *digest* ) and serial number *serial\_number* .

The information needed corresponds to the CertID structure:

&lt;informalexample&gt;&lt;programlisting&gt; CertID ::= SEQUENCE { hashAlgorithm AlgorithmIdentifier, issuerNameHash OCTET STRING, -- Hash of Issuer's DN issuerKeyHash OCTET STRING, -- Hash of Issuers public key serialNumber CertificateSerialNumber } &lt;/programlisting&gt;&lt;/informalexample&gt;

# [RETURNS](#RETURNS)

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