NAME¶
Crypt::Stream::Sober128 - Stream cipher Sober128
SYNOPSIS¶
use Crypt::Stream::Sober128;
# encrypt
$key = "1234567890123456";
$iv = "123456789012";
$stream = Crypt::Stream::Sober128->new($key, $iv);
$ct = $stream->crypt("plain message");
# decrypt
$key = "1234567890123456";
$iv = "123456789012";
$stream = Crypt::Stream::Sober128->new($key, $iv);
$pt = $stream->crypt($ct);
DESCRIPTION¶
Provides an interface to the Sober128 stream cipher.
METHODS¶
new¶
$stream = Crypt::Stream::Sober128->new($key, $iv);
# $key .. keylen must be multiple of 4 bytes
# $iv .. ivlen must be multiple of 4 bytes
crypt¶
$ciphertext = $stream->crypt($plaintext);
#or
$plaintext = $stream->crypt($ciphertext);
keystream¶
$random_key = $stream->keystream($length);
