The encryption is EDE with Blowfish CBC. To decode the cryptotext ct reverse the encrytion, ie do CBC_Decrypt(key3, iv3, ct, t3) CBC_Encrypt(key2, iv2, t3, t2) CBC_Decrypt(key1, iv1, t2, pt) After this the plaintext pt will start with: El truco estaba en desencriptar utilizando el metodo 3DES pero con distintos algoritmos de encripcion. Aunque usualmente ...
