32 -- This package provides a generic hashing function over strings, suitable for
33 -- use with a string keyed hash table. In particular, it is the basis for the
34 -- string hash functions in Ada.Containers.
36 -- The algorithm used here is not appropriate for applications that require
37 -- cryptographically strong hashes, or for applications that wish to use very
38 -- wide hash values as pseudo unique identifiers. In such cases please refer
39 -- to GNAT.SHA1 and GNAT.MD5.
