mcrypt has (old) crypt compatibility but if that isn't a requirement then the openssl package can be made to do much the same thing very easily.

    openssl des3 -salt -pass pass:X  <plaintext  >ciphertext
    openssl des3 -d -pass pass:X  <ciphertext  >plaintext

You can choose a different cipher if you like - they're all better than the crippled Enigma one that crypt used to use - although a passphrase better than a single "X" character is probably a good idea.
