-- 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.
-- 
-- To create a new @GChecksum@, use 'GI.GLib.Structs.Checksum.checksumNew'. To free
-- a @GChecksum@, use 'GI.GLib.Structs.Checksum.checksumFree'.
-- 
-- GLib supports incremental checksums using the @GChecksum@ data
-- structure, by calling 'GI.GLib.Structs.Checksum.checksumUpdate' as long as there’s data
-- available and then using 'GI.GLib.Structs.Checksum.checksumGetString' or
-- t'GI.GLib.Structs.Checksum.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 'GI.GLib.Functions.computeChecksumForData'
-- and 'GI.GLib.Functions.computeChecksumForString', respectively.
