    Summary: Crypt-RIPEMD160 - Perl extension for the RIPEMD-160 Hash function
    Description: 
    The Crypt::RIPEMD160 module allows you to use the RIPEMD160
    Message Digest algorithm from within Perl programs.
    
    The module is based on the implementation from Antoon Bosselaers from
    Katholieke Universiteit Leuven.
    
    A new RIPEMD160 context object is created with the new operation.
    Multiple simultaneous digest contexts can be maintained, if desired.
    The context is updated with the add operation which adds the
    strings contained in the *LIST* parameter. Note, however, that
    "add('foo', 'bar')", "add('foo')" followed by "add('bar')" and
    "add('foobar')" should all give the same result.
    
    The final message digest value is returned by the digest operation
    as a 20-byte binary string. This operation delivers the result of
    add operations since the last new or reset operation. Note
    that the digest operation is effectively a destructive, read-once
    operation. Once it has been performed, the context must be reset
    before being used to calculate another digest value.
    
    Several convenience functions are also provided. The addfile
    operation takes an open file-handle and reads it until end-of file in
    8192 byte blocks adding the contents to the context. The file-handle
    can either be specified by name or passed as a type-glob reference, as
    shown in the examples below. The hexdigest operation calls
    digest and returns the result as a printable string of hexdecimal
    digits. This is exactly the same operation as performed by the
    unpack operation in the examples below.
    
    The hash operation can act as either a static member function (ie
    you invoke it on the RIPEMD160 class as in the synopsis above) or as a
    normal virtual function. In both cases it performs the complete RIPEMD160
    cycle (reset, add, digest) on the supplied scalar value. This is
    convenient for handling small quantities of data. When invoked on the
    class a temporary context is created. When invoked through an already
    created context object, this context is used. The latter form is
    slightly more efficient. The hexhash operation is analogous to
    hexdigest.
