NAME gnutls_x509_crt_get_fingerprint - API function

SYNOPSIS #include <gnutls/x509.h>

int gnutls_x509_crt_get_fingerprint(gnutls_x509_crt_t cert, gnutls_digest_algorithm_t algo, void * buf, size_t * sizeof_buf);

ARGUMENTS gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t structure

gnutls_digest_algorithm_t algo is a digest algorithm

void * buf a pointer to a structure to hold the fingerprint (may be null)

size_t * sizeof_buf initially holds the size of buf

DESCRIPTION This function will calculate and copy the certificates fingerprint in the provided buffer.

If the buffer is null then only the size will be filled.

RETURNS GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the *sizeof_buf will be updated with the required size. On success 0 is returned.
