crypt::des

DES(3)							User Contributed Perl Documentation						    DES(3)

NAME

       Crypt::DES - Perl DES encryption module

SYNOPSIS

	   use Crypt::DES;

DESCRIPTION

       The module implements the Crypt::CBC interface, which has the following methods

       blocksize =item keysize =item encrypt =item decrypt

FUNCTIONS

       blocksize
	   Returns the size (in bytes) of the block cipher.

       keysize
	   Returns the size (in bytes) of the key. Optimal size is 8 bytes.

       new
		   my $cipher = new Crypt::DES $key;

	   This creates a new Crypt::DES BlockCipher object, using $key, where $key is a key of "keysize()" bytes.

       encrypt
		   my $cipher = new Crypt::DES $key;
		   my $ciphertext = $cipher->encrypt($plaintext);

	   This function encrypts $plaintext and returns the $ciphertext where $plaintext and $ciphertext should be of "blocksize()" bytes.

       decrypt
		   my $cipher = new Crypt::DES $key;
		   my $plaintext = $cipher->decrypt($ciphertext);

	   This function decrypts $ciphertext and returns the $plaintext where $plaintext and $ciphertext should be of "blocksize()" bytes.

EXAMPLE

	       my $key = pack("H16", "0123456789ABCDEF");
	       my $cipher = new Crypt::DES $key;
	       my $ciphertext = $cipher->encrypt("plaintex");  # NB - 8 bytes
	       print unpack("H16", $ciphertext), "
";

NOTES

       Do note that DES only uses 8 byte keys and only works on 8 byte data blocks.  If you're intending to encrypt larger blocks or entire files,
       please use Crypt::CBC in conjunction with this module.  See the Crypt::CBC documentation for proper syntax and use.

       Also note that the DES algorithm is, by today's standard, weak encryption.  Crypt::Blowfish is highly recommended if you're interested in
       using strong encryption and a faster algorithm.
