NAME

Digest::Skein - Perl interface to the Skein digest algorithm

SYNOPSIS

  use Digest::Skein qw/ skein_512 skein_512_hex /;
  my $digest    = skein_512('foo bar baz');
  my $hexdigest = skein_512_hex('foo bar baz');

OO interface:

  my $digest = Digest::Skein->new(512)->add('foo bar baz')->digest;
  my $base64 = Digest::Skein->new(512)->add('foo bar baz')->b64digest;

  # using the Digest API
  my $hex    = Digest->Skein(256)->add('foo bar baz')->hexdigest;
  my $base64 = Digest->new('Skein')->add('foo bar baz')->b64digest;   # default is 512
  my $digest = Digest->new('Skein', 512)->add('foo bar baz')->digest; # ...just like here
