| libcrypt-des-ede3-perl | Triple-DES EDE encryption/decryption for perl | Mehr ... |
Crypt::DES_EDE3 implements DES-EDE3 encryption. This is triple-DES
encryption where an encrypt operation is encrypt-decrypt-encrypt, and
decrypt is decrypt-encrypt-decrypt. This implementation uses Crypt::DES
to do its dirty DES work, and simply provides a wrapper around that
module: setting up the individual DES ciphers, initializing the keys,
and performing the encryption/decryption steps.
.
You're probably best off not using this module directly, as the encrypt
and decrypt methods expect 8-octet blocks. You might want to use the
module in conjunction with Crypt::CBC, for example. This would be
DES-EDE3-CBC, or triple-DES in outer CBC mode. |
