File::KDBX::Cipher::Stream(3p)

NAME
File::KDBX::Cipher::Stream - A cipher stream encrypter/decrypter

VERSION
version 0.906

SYNOPSIS
    use File::KDBX::Cipher::Stream;

    my $cipher = File::KDBX::Cipher::Stream->new(algorithm => $algorithm, key => $key, iv => $iv);

DESCRIPTION
A subclass of File::KDBX::Cipher for encrypting and decrypting data using a stream cipher.

ATTRIBUTES

  counter
    $counter = $cipher->counter;

Get the initial counter / block count into the keystream.

  offset
    $offset = $cipher->offset;

Get the initial byte offset into the keystream. This has precedence over "counter" if both are set.

METHODS

  crypt
    $ciphertext = $cipher->crypt($plaintext);
    $plaintext = $cipher->crypt($ciphertext);

Encrypt or decrypt some data. These ciphers are symmetric, so encryption and decryption are the same operation. This method is an alias for both "encrypt" in File::KDBX::Cipher and "decrypt" in File::KDBX::Cipher.

  keystream
    $stream = $cipher->keystream;

Access the keystream.

  dup
    $cipher_copy = $cipher->dup(%attributes);

Get a copy of an existing cipher with the counter reset, optionally applying new attributes.
