<!-- ##### SECTION Title ##### -->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 asequence of arbitrary bytes, using various hashing algorithms like MD5,SHA-1 and SHA-256. Checksums are commonly used in various environments andspecifications.</para><para>GLib supports incremental checksums using the GChecksum data structure, bycalling g_checksum_update() as long as there's data available and then usingg_checksum_get_string() or g_checksum_get_digest() to compute the checksumand return it either as a string in hexadecimal form, or as a raw sequenceof bytes. To compute the checksum for binary blobs and NUL-terminated stringsin one go, use the convenience functions g_compute_checksum_for_data() andg_compute_checksum_for_string(), respectively.</para><para>Support for checksums has been added in GLib 2.16</para><!-- ##### SECTION See_Also ##### --><para></para><!-- ##### SECTION Stability_Level ##### --><!-- ##### ENUM GChecksumType ##### --><para></para>@G_CHECKSUM_MD5: @G_CHECKSUM_SHA1: @G_CHECKSUM_SHA256: <!-- ##### FUNCTION g_checksum_type_get_length ##### --><para></para>@checksum_type: @Returns: <!-- ##### STRUCT GChecksum ##### --><para></para><!-- ##### FUNCTION g_checksum_new ##### --><para></para>@checksum_type: @Returns: <!-- ##### FUNCTION g_checksum_copy ##### --><para></para>@checksum: @Returns: <!-- ##### FUNCTION g_checksum_free ##### --><para></para>@checksum: <!-- ##### FUNCTION g_checksum_update ##### --><para></para>@checksum: @data: @length: <!-- ##### FUNCTION g_checksum_get_string ##### --><para></para>@checksum: @Returns: <!-- ##### FUNCTION g_checksum_get_digest ##### --><para></para>@checksum: @buffer: @digest_len: <!-- ##### FUNCTION g_compute_checksum_for_data ##### --><para></para>@checksum_type: @data: @length: @Returns: <!-- ##### FUNCTION g_compute_checksum_for_string ##### --><para></para>@checksum_type: @str: @length: @Returns:
