Data Checksums
<!-- ##### SECTION Short_Description ##### -->
Computes the checksum for data
<!-- ##### SECTION Long_Description ##### -->
<para>
GLib provides a generic API for computing checksums (or "digests") for a
sequence of arbitrary bytes, using various hashing algorithms like MD5,
SHA-1 and SHA-256. Checksums are commonly used in various environments and
specifications.
</para>
<para>
GLib supports incremental checksums using the GChecksum data structure, by
calling g_checksum_update() as long as there's data available and then using
g_checksum_get_string() or g_checksum_get_digest() to compute the checksum
and return it either as a string in hexadecimal form, or as a raw sequence
of bytes. To compute the checksum for binary blobs and NUL-terminated strings
in one go, use the convenience functions g_compute_checksum_for_data() and
g_compute_checksum_for_string(), respectively.
</para>
<para>
Support for checksums has been added in GLib 2.16
