To encrypt, something like: openssl enc -e -des -in plaintext.txt -a -out encrypted.asc Decrypt like so: openssl enc -d -dex -in encrypted.asc -a -out plaintext.txt Note: completely untested. You may well need to supply various extra arguments to make it all work. See 'openssl enc help' for hints. Note 2: DES is pretty trivial to crack nowadays. Don't use this for anything serious. You can encrypt using AES or any of a host of other ciphers by using a very similar openssl command line. Note 3: If you're actually after DES "encrypted" passwords, then see crypt(3). From the commandline you can use the Perl crypt function: 'perldoc -f crypt' for details.
