@deftypefun {int} {gnutls_pubkey_get_pk_algorithm} (gnutls_pubkey_t @var{key}, unsigned int * @var{bits})

@var{key}: should contain a @code{gnutls_pubkey_t}  type

@var{bits}: If set will return the number of bits of the parameters (may be NULL)

This function will return the public key algorithm of a public

key and if possible will return a number of bits that indicates

the security parameter of the key.

@strong{Returns:} a member of the @code{gnutls_pk_algorithm_t}  enumeration on

success, or a negative error code on error.

@strong{Since:} 2.12.0
