Crypt::AllOrNothing
All-Or-Nothing Encryption

Crypt::AllOrNothing - All-Or-Nothing Encryption


NAME

Crypt::AllOrNothing - All-Or-Nothing Encryption


VERSION

Version 0.10


SYNOPSIS


  use Crypt::AllOrNothing;

  my $AllOrNothing = Crypt::AllOrNothing->new(K_0=>$K_0);

  my $K_0 = $AllOrNothing->get_K_0();

  my $K_0 = $AllOrNothing->set_K_0($K_0);

  my $size = $AllOrNothing->get_size();

  my @AllOrNothing_text = $AllOrNothing->encrypt(text=>$plaintext);

  my $plaintext = $AllOrNothing->decrypt(text=>@AllOrNothing_text);


CONSTANTS


  $SIZE = 128 bits;


FUNCTIONS

new(K_0=>$K_0)

Create AllOrNothing object. Good idea to provide K_0, which must be ascii encoded(characters) and of length given in size. If K_0 is not given, you must retrieve it later with $AllOrNothing->K_0() else you will not be able to decrypt the message.

K_0(K_0=>$K_0)

get/set K_0. K_0 must be ascii encoded(characters) and length given in size.

size()

get size.

@ciphertext = encrypt(plaintext=>$plaintext, padding=>$padding)

encrypt plaintext with All Or Nothing transform to array of messages. Optionally pass padding which will be used internally

$plaintext = decrypt(cryptotext=>\@cryptotext)

decrypt cryptotext array with All Or Nothing transform to plaintext
