Hmac

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 glib.hmac.Hmac, use glib.hmac.Hmac.new_. To free a glib.hmac.Hmac, use glib.hmac.Hmac.unref.

class Hmac : Boxed {

this(glib.types.ChecksumType digestType, ubyte[] key);

glib.hmac.Hmac copy();

void getDigest(ubyte[] buffer);

string getString();

void update(ubyte[] data);

}

Constructors

this this(glib.types.ChecksumType digestType, ubyte[] key): 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.

Functions

copy glib.hmac.Hmac copy(): Copies a #GHmac. If hmac has been closed, by calling glib.hmac.Hmac.getString or glib.hmac.Hmac.getDigest, the copied HMAC will be closed as well.
getDigest void getDigest(ubyte[] buffer): 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.
getString string getString(): Gets the HMAC as a hexadecimal string.
update void update(ubyte[] data): Feeds data into an existing #GHmac.
