Hmac.this

Creates a new #GHmac, using the digest algorithm @digest_type. If the @digest_type is not known, %NULL is returned. A #GHmac can be used to compute the HMAC of a key and an arbitrary binary blob, using different hashing algorithms.

A #GHmac works by feeding a binary blob through g_hmac_update() 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_string() or g_hmac_get_digest() have been called on a #GHmac, the HMAC will be closed and it won't be possible to call g_hmac_update() on it anymore.

Support for digests of type %G_CHECKSUM_SHA512 has been added in GLib 2.42.
