Struct
GLibHmac
since: 2.30
Description [src]
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.
