gnutls_fingerprint(3)						      gnutls						     gnutls_fingerprint(3)

NAME

       gnutls_fingerprint - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_fingerprint(gnutls_digest_algorithm_t algo, const gnutls_datum_t * data, void * result, size_t * result_size);

ARGUMENTS

       gnutls_digest_algorithm_t algo
		   is a digest algorithm

       const gnutls_datum_t * data
		   is the data

       void * result
		   is the place where the result will be copied (may be null).

       size_t * result_size
		   should hold the size of the result. The actual size of the returned result will also be copied there.

DESCRIPTION

       This  function will calculate a fingerprint (actually a hash), of the given data.  The result is not printable data.  You should convert it
       to hex, or to something else printable.

       This is the usual way to calculate a fingerprint of an X.509 DER encoded certificate.  Note however that the fingerprint of an OpenPGP cer-
       tificate is not just a hash and cannot be calculated with this function.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.

NAME

       gnutls_pem_base64_encode - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       int gnutls_pem_base64_encode(const char * msg, const gnutls_datum_t * data, char * result, size_t * result_size);

ARGUMENTS

       const char * msg
		   is a message to be put in the header

       const gnutls_datum_t * data
		   contain the raw data

       char * result
		   the place where base64 data will be copied

       size_t * result_size
		   holds the size of the result

DESCRIPTION

       This function will convert the given data to printable data, using the base64 encoding. This is the encoding used in PEM messages.

       The output string will be null terminated, although the size will not include the terminating null.

RETURNS

       On  success GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_SHORT_MEMORY_BUFFER is returned if the buffer given is not long enough, or 0 on suc-
       cess.
