3. Information about the perl-Crypt-Rijndael package on openSUSE Leap

Information for package perl-Crypt-Rijndael:
--------------------------------------------
Repository : Main Repository
Name : perl-Crypt-Rijndael
Version : 1.13-150000.3.4.1
Arch : x86_64
Vendor : SUSE LLC
Installed Size : 42.4 KiB
Installed : No
Status : not installed
Source package : perl-Crypt-Rijndael-1.13-150000.3.4.1.src
Upstream URL : http://search.cpan.org/dist/Crypt-Rijndael/
Summary : Crypt::CBC compliant Rijndael encryption module
Description :
This module implements the Rijndael cipher, which has just been selected as
the Advanced Encryption Standard.
* keysize
Returns the keysize, which is 32 (bytes). The Rijndael cipher actually
supports keylengths of 16, 24 or 32 bytes, but there is no way to
communicate this to 'Crypt::CBC'.
* blocksize
The blocksize for Rijndael is 16 bytes (128 bits), although the algorithm
actually supports any blocksize that is any multiple of our bytes. 128
bits, is however, the AES-specified block size, so this is all we
support.
* $cipher = Crypt::Rijndael->new( $key [, $mode] )
Create a new 'Crypt::Rijndael' cipher object with the given key (which
must be 128, 192 or 256 bits long). The additional '$mode' argument is
the encryption mode, either 'MODE_ECB' (electronic codebook mode, the
default), 'MODE_CBC' (cipher block chaining, the same that 'Crypt::CBC'
does), 'MODE_CFB' (128-bit cipher feedback), 'MODE_OFB' (128-bit output
feedback), or 'MODE_CTR' (counter mode).
ECB mode is very insecure (read a book on cryptography if you don't know
why!), so you should probably use CBC mode.
* $cipher->set_iv($iv)
This allows you to change the initial value vector used by the chaining
modes. It is not relevant for ECB mode.
* $cipher->encrypt($data)
Encrypt data. The size of '$data' must be a multiple of 'blocksize' (16
bytes), otherwise this function will croak. Apart from that, it can be of
(almost) any length.
* $cipher->decrypt($data)
Decrypts '$data'.
