=head1 NAME
Crypt::Digest::CHAES - Hash function - CipherHash based on AES [size: 128 bits]
=head1 SYNOPSIS
### Functional interface:
use Crypt::Digest::CHAES qw( chaes chaes_hex chaes_base64 chaes_file chaes_file_hex chaes_file_base64 );
# calculate digest from string/buffer
$chaes_raw = chaes('data string');
$chaes_hex = chaes_hex('data string');
$chaes_b64 = chaes_base64('data string');
# calculate digest from file
$chaes_raw = chaes_file('filename.dat');
$chaes_hex = chaes_file_hex('filename.dat');
$chaes_b64 = chaes_file_base64('filename.dat');
# calculate digest from filehandle
$chaes_raw = chaes_file(*FILEHANDLE);
$chaes_hex = chaes_file_hex(*FILEHANDLE);
$chaes_b64 = chaes_file_base64(*FILEHANDLE);
### OO interface:
use Crypt::Digest::CHAES;
$d = Crypt::Digest::CHAES->new;
$d->add('any data');
$d->addfile('filename.dat');
$d->addfile(*FILEHANDLE);
$result_raw = $d->digest; # raw bytes
$result_hex = $d->hexdigest; # hexadecimal form
$result_b64 = $d->b64digest; # Base64 form
=head1 DESCRIPTION
Provides an interface to the CHAES digest algorithm.
=head1 EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::CHAES qw(chaes chaes_hex chaes_base64 chaes_file chaes_file_hex chaes_file_base64);
Or all of them at once:
use Crypt::Digest::CHAES ':all';
=head1 FUNCTIONS
=head2 chaes
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a binary string.
$chaes_raw = chaes('data string');
#or
$chaes_raw = chaes('any data', 'more data', 'even more data');
=head2 chaes_hex
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a hexadecimal string.
$chaes_hex = chaes_hex('data string');
#or
$chaes_hex = chaes('any data', 'more data', 'even more data');
=head2 chaes_base64
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a Base64 string, B<with> trailing '=' padding.
$chaes_base64 = chaes_base64('data string');
#or
$chaes_base64 = chaes('any data', 'more data', 'even more data');
=head2 chaes_file
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a binary string.
$chaes_raw = chaes_file('filename.dat');
#or
$chaes_raw = chaes_file(*FILEHANDLE);
=head2 chaes_file_hex
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a hexadecimal string.
$chaes_hex = chaes_file_hex('filename.dat');
#or
$chaes_hex = chaes_file_hex(*FILEHANDLE);
B<BEWARE:> You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
=head2 chaes_file_base64
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a Base64 string, B<with> trailing '=' padding.
$chaes_base64 = chaes_file_base64('filename.dat');
#or
$chaes_base64 = chaes_file_base64(*FILEHANDLE);
=head1 METHODS
The OO interface provides the same set of functions as L<Crypt::Digest>.
=head2 new
$d = Crypt::Digest::CHAES->new();
=head2 clone
$d->clone();
=head2 reset
$d->reset();
=head2 add
$d->add('any data');
#or
$d->add('any data', 'more data', 'even more data');
=head2 addfile
$d->addfile('filename.dat');
#or
$d->addfile(*FILEHANDLE);
=head2 add_bits
$d->addfile('filename.dat');
#or
$d->addfile(*FILEHANDLE);
=head2 hashsize
$d->hashsize;
#or
Crypt::Digest::CHAES->hashsize();
#or
Crypt::Digest::CHAES::hashsize();
=head2 digest
$result_raw = $d->digest();
=head2 hexdigest
$result_hex = $d->hexdigest();
=head2 b64digest
$result_base64 = $d->b64digest();
