Description
struct GHmac {
/* No available fields */
}
HMACs should be used when producing a cookie or hash based on data and a key. Simple mechanisms for using SHA1 and other algorithms to digest a key and data together are vulnerable to various security issues. HMAC uses algorithms like SHA1 in a secure way to produce a digest of a key and data.
Both the key and data are arbitrary byte arrays of bytes or characters.
Support for HMAC Digests has been added in GLib 2.30, and support for SHA-512 in GLib 2.42. Support for SHA-384 was added in GLib 2.52.
To create a new GHmac, use g_hmac_new(). To free a GHmac, use
g_hmac_unref().
Available since: 2.30
Constructors
g_hmac_new
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.

Instance methods
g_hmac_copy
Copies a GHmac. If hmac has been closed, by calling
g_hmac_get_string() or g_hmac_get_digest(), the copied
HMAC will be closed as well.
since: 2.30
g_hmac_get_digest
Gets the digest from checksum as a raw binary array and places it
into buffer. The size of the digest depends on the type of checksum.
