Crypt::Stream::ChaCha - Stream cipher ChaCha
use Crypt::Stream::ChaCha; # encrypt $key = "1234567890123456"; $iv = "123456789012"; $stream = Crypt::Stream::ChaCha->new($key, $iv); $ct = $stream->crypt("plain message"); # decrypt $key = "1234567890123456"; $iv = "123456789012"; $stream = Crypt::Stream::ChaCha->new($key, $iv); $pt = $stream->crypt($ct);
Provides an interface to the ChaCha stream cipher.

$ciphertext = $stream->crypt($plaintext); #or $plaintext = $stream->crypt($ciphertext);
$random_key = $stream->keystream($length);
$stream->clone();
