int gnutls_x509_crt_get_pk_oid(gnutls_x509_crt_t cert, char * oid, size_t * oid_size);
- gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
- char * oid
a pointer to a buffer to hold the OID (may be null)
- size_t * oid_size
initially holds the size of oid
This function will return the OID of the public key algorithm on that certificate. This is function is useful in the case gnutls_x509_crt_get_pk_algorithm() returned GNUTLS_PK_UNKNOWN.
zero or a negative error code on error.
