WebAug 9, 2010 · Depending on which cipher and mode you use, it will vary. CBC is the most popular mode, which requires the IV and requires plaintext be padded up to the block size. So, let's say you want to encrypt 4 bytes with AES CBC. You would need 16 bytes for the IV, and those 4 bytes need to be padded to 16 bytes, for a total of 32 bytes.

WebIn case you expect DES and you're ready to spend quite a while, it is doable. If it is a toy or exercise cipher, you should get lucky. In case you expect that the encryption key is actually based on a (possibly) weak password, then the most effective way to crack the encryption is likely to brute-force the password instead of the key. With the advent of computing, the term plaintext expanded beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without requiring a key or other decryption device. Information—a message, document, file, etc.—if to be communicated or stored in an unencrypted form is referred to as plaintext. Plaintext is used as input to an encryption algorithm; the output is usually termed ciphertext, parti…
