I want to combine hashing and encryption for better security. So can I use a hash key generated from SHA-512 as a key in AES. For example, I have a password 'secret', I calculate SHA-512 hash for it and I want to feed those bytes as key for AES. What things I need to care while implementing this? And that is all there is to encrypting and decrypting a file using AES in python. We need to generate or obtain a key, create the initialization vector and write the original file size followed by the IV into the output file. This is followed by the encrypted data. Finally decryption does the same process in reverse.

Monster hunter generations ultimate key quest not showing up. This only works because the 'mysecretpassword' is 16 bytes. If it were a different (not dividable by 16) amount of bytes you'd get 'ValueError: AES key must be either 16, 24, or 32 bytes long' To avoid this the key may be hashed: self.key = hashlib.sha256(key.encode('utf-8')).digest() |

In Python 3 using the modifications of Craz1k0ek it still doesn't work with Unicode. https://poweruppolar934.weebly.com/titan-quest-serial-key-generator.html. For example the input Hello, 你好 raises ValueError: Input strings must be a multiple of 16 in length Edit: found a working version: https://stackoverflow.com/a/44212550 |

i think this is aes 128, we have a standard blocksize of 16 bytes (128bit) |
