WebSimple Encryption/Decryption using AES. To encrypt a file called myfile.txt using AES in CBC mode, run: openssl enc -aes-256-cbc -salt -in myfile.txt -out myfile.enc. This will prompt you for a password, then create the encrypted file myfile.enc (NB: use a strong password and don't forget it, as you'll need it for the decryption stage!).
