=head1 NAME

IDEA - Perl interface to IDEA block cipher

=head1 SYNOPSIS

use Crypt::IDEA;

=head1 DESCRIPTION

This perl extension is an implementation of the IDEA block cipher algorithm.
The module implements the Crypt::BlockCipher interface,
which has the following methods

=over 4

=item blocksize
=item keysize
=item encrypt
=item decrypt

=back

=head1 FUNCTIONS

=over 4

=item blocksize

Returns the size (in bytes) of the block cipher.

=item keysize

Returns the size (in bytes) of the key.

=item new

my $cipher = new IDEA $key;

This creates a new IDEA BlockCipher object, using $key,
where $key is a key of C<keysize()> bytes.

=item encrypt

my $cipher = new IDEA $key;
	my $ciphertext = $cipher->encrypt($plaintext);

This function encrypts $plaintext and returns the $ciphertext
where $plaintext and $ciphertext should be of C<blocksize()> bytes.

=item decrypt

my $cipher = new IDEA $key;
	my $plaintext = $cipher->decrypt($ciphertext);

This function decrypts $ciphertext and returns the $plaintext
where $plaintext and $ciphertext should be of C<blocksize()> bytes.

=back

=head1 EXAMPLE

my $key = pack("H32", "0123456789ABCDEF0123456789ABCDEF");
	my $cipher = new IDEA $key;
	my $ciphertext = $cipher->encrypt("plaintex");	# NB - 8 bytes
	print unpack("H16", $ciphertext), "\n";

Module altered between 1999 and 2005  to allow added functionality with perl -MCPAN,
Changes by Dave Paris  (edited lib paths, endian issues, new tests).

Thank you to contributors for endian patches and new test suite!
