# [NAME](#NAME)

gnutls\_pem\_base64\_decode - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_pem\_base64\_decode(const char * header, const gnutls\_datum\_t * b64\_data, unsigned char * result, size\_t * result\_size);**

# [ARGUMENTS](#ARGUMENTS)

[const char * header](#const)

A null terminated string with the PEM header (eg. CERTIFICATE)

[const gnutls\_datum\_t * b64\_data](#const~2)

contain the encoded data

[unsigned char * result](#unsigned)

the place where decoded data will be copied

[size\_t * result\_size](#size_t)

holds the size of the result

# [DESCRIPTION](#DESCRIPTION)

This function will decode the given encoded data. If the header given is non **NULL** this function will search for "-----BEGIN header" and decode only this part. Otherwise it will decode the first PEM packet found.
