# gnutls\_x509\_ct\_sct\_get(3)

API function

## NAME

gnutls\_x509\_ct\_sct\_get - API function

## SYNOPSIS

**#include \<gnutls/x509-ext.h\>**

**int gnutls\_x509\_ct\_sct\_get(const gnutls\_x509\_ct\_scts\_t** *scts***, unsigned** *idx***, time\_t \*** *timestamp***, gnutls\_datum\_t \*** *logid***, gnutls\_sign\_algorithm\_t \*** *sigalg***, gnutls\_datum\_t \*** *signature***);**

## ARGUMENTS

- const gnutls\_x509\_ct\_scts\_t scts

  A list of SCTs

- unsigned idx

  The index of the target SCT in the list

- time\_t \* timestamp

  The timestamp of the SCT

- gnutls\_datum\_t \* logid

  The LogID field of the SCT; must be freed with **gnutls\_free()**

- gnutls\_sign\_algorithm\_t \* sigalg

  The signature algorithm

- gnutls\_datum\_t \* signature

  The signature of the SCT; must be freed with **gnutls\_free()**

## DESCRIPTION

This function will return a specific SCT (Signed Certificate Timestamp) stored in the SCT list  *scts* .

The datums holding the SCT's LogId and signature will be allocated using **gnutls\_malloc()**.

## RETURNS

**GNUTLS\_E\_SUCCESS** (0) will be returned on success, **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** if  *idx* exceeds the number of SCTs in the list or a negative error value.
