Crypt::Cipher::SAFER_K64(3)
NAME
Crypt::Cipher::SAFER_K64 - Symmetric cipher SAFER_K64, key size: 64 bits
SYNOPSIS
### example 1 use Crypt::Mode::CBC; my $key = '...'; # length has to be valid key size for this cipher my $iv = '...'; # 16 bytes my $cbc = Crypt::Mode::CBC->new('SAFER_K64'); my $ciphertext = $cbc->encrypt("secret data", $key, $iv); ### example 2 (slower) use Crypt::CBC; use Crypt::Cipher::SAFER_K64; my $key = '...'; # length has to be valid key size for this cipher my $iv = '...'; # 16 bytes my $cbc = Crypt::CBC->new( -cipher=>'Cipher::SAFER_K64', -key=>$key, -iv=>$iv ); my $ciphertext = $cbc->encrypt("secret data");
DESCRIPTION
This module implements the SAFER_K64 cipher. Provided interface is compliant with Crypt::CBC module. BEWARE: This module implements just elementary "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt generic data you have to use some of the cipher block modes - check for example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be slower).
METHODS
new $c = Crypt::Cipher::SAFER_K64->new($key); #or $c = Crypt::Cipher::SAFER_K64->new($key, $rounds); encrypt $ciphertext = $c->encrypt($plaintext); decrypt $plaintext = $c->decrypt($ciphertext); keysize $c->keysize; #or Crypt::Cipher::SAFER_K64->keysize; #or Crypt::Cipher::SAFER_K64::keysize; blocksize $c->blocksize; #or Crypt::Cipher::SAFER_K64->blocksize; #or Crypt::Cipher::SAFER_K64::blocksize; max_keysize $c->max_keysize; #or Crypt::Cipher::SAFER_K64->max_keysize; #or Crypt::Cipher::SAFER_K64::max_keysize; min_keysize $c->min_keysize; #or Crypt::Cipher::SAFER_K64->min_keysize; #or Crypt::Cipher::SAFER_K64::min_keysize; default_rounds $c->default_rounds; #or Crypt::Cipher::SAFER_K64->default_rounds; #or Crypt::Cipher::SAFER_K64::default_rounds;
