Digest::Whirlpool - A 512-bit, collision-resistant, one-way hash function
WHIRLPOOL is a 512-bit, collision-resistant, one-way hash function developed by Paulo S. L. M. Barreto and Vincent Rijmen. It has been recommended by the NESSIE project (along with SHA-256/384/512) and adopted as ISO/IEC 10118-3.
# Using L<Digest> (recommended) use Digest; my $whirlpool = Digest->new( 'Whirlpool' ); # Get a hash and reset the object $whirlpool->add( "hash this" ); my $hexdigest = $whirlpool->hexdigest; # Populate the object again, and clone it before getting the # digest to avoid resetting $whirlpool->add( "hash this" ); my $b64digest = $whirlpool->clone->b64digest; $whirlpool->add( "add this to the hash" ); # Using this module directly (same interface) use Digest::Whirlpool; my $whirlpool = Digest->new( 'Whirlpool' ); $whirlpool->add( ... ); ....
From the command line:
whirlpoolsum files whirlpoolsum --help
Since this module implements the standard Digest interface and should be used through the Digest module you should look at that documentation for the general interface, below is a description of methods that differ.
Copy the internal state of the current object into a new object and return it.
Resets the object to the same internal state it was in when it was constructed.
This works exactly like "new" except it doesn't allocate new memory for its internal state.
An legacy alias for the b64digest method which should be used instead.
Returns the size (in bits) of a WHIRLPOOL hash, i.e. 512.

The original version of this package was written by Julius C. Duque in 2003. It was rewritten by Ævar Arnfjörð Bjarmason <email@example.com> in January 2007 who added compatability with the Digest interface, improved documentation and a whirlpoolsum(1) command-line utility amongst other things.
