Creates a new
GHmac, using the digest algorithm
digest_type is not known,
NULL is returned.
GHmac can be used to compute the HMAC of a key and an
arbitrary binary blob, using different hashing algorithms.
GHmac works by feeding a binary blob through
until the data is complete; the digest can then be extracted
using g_hmac_get_string(), which will return the checksum as a
hexadecimal string; or g_hmac_get_digest(), which will return a
array of raw bytes. Once either
g_hmac_get_digest() have been called on a
GHmac, the HMAC
will be closed and it won’t be possible to call
on it anymore.
Support for digests of type
G_CHECKSUM_SHA512 has been added in GLib 2.42.
G_CHECKSUM_SHA384 was added in GLib 2.52.
Available since: 2.30
