%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*.
