WebEncrypt a file using triple DES in CBC mode using a prompted password: openssl des3 -salt -in file.txt -out file.des3 Decrypt a file using a supplied password: openssl des3 -d -salt -in file.des3 -out file.txt -k mypassword Encrypt a file then base64 encode it (so it can be sent via mail for example) using Blowfish in CBC mode: WebCipher Block Chaining (CBC) For CBC mode, the first step is to generate a random initialization vector (IV) of 16 bytes. Next, XOR the IV and the first 16 bytes of your plaintext to get input for AES. That creates the first 16 bytes of the ciphertext (often the IV is sent as the actual first 16 bytes). download music sjava umcebo
