gnutls_x509_crt_get_fingerprint - API function
#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);
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
This function will calculate and copy the certificate's fingerprint in the provided buffer. If the buffer is null then only the size will be filled.
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.
