The program prompts for a password or passphrase and a message to encrypt/ decrypt. The block length for Blowfish is 64 bits; messages that aren't a multiple of eight bytes in size must be padded. Your "Test" example also illustrates this. How does Secure Shell work? Without the private RSA keys, which never go over the airwaves, the eavesdropper can't obtain the Blowfish keys and, therefore, can't decrypt the messages passed between the two machines. And of course, most encryption algorithms can also assure data privacy, a way to prevent someone other than the intended recipient from reading the message. Finally, we don't know if the secret is being concatenated with a salt before being hashed. Since the strength of encryption depends on the length of the password, apparently it does not apply to blowfish. Asking for help, clarification, or responding to other answers. Can I ask for a refund or credit next year? initialization vector. The process of encryption converts that plaintext message into ciphertext, and decryption converts the ciphertext back into plaintext. On the Disadvantage side, it takes a very long time to do, The small block size of Blowfish means that Birthday Attacks can occur and compromise the encryption algorithm, It is followed by Twofish, which was created to replace Blowfish, as it is better in most ways. The test vectors for verifying third-party implementations were also produced with 576-bit keys. The downside to this approach is that the Blowfish key in the embedded system has to be kept secret, which can be difficult to achieve for a truly determined attacker with hardware skills.
