Password-based Encryption

Fernet encrypt strings using a key generated based on a string password.

Fernet (AES CBC with random IV + HMAC SHA256 and PKCS7 padding) with password.

Key derived with PBKDF2HMAC: salted 100k times hashed (SHA3_256) password.

Installing

Using

message = "The fox jumps over the lazy dog."
password = "2 strong & SECURE pa$$word"
cipher_text = PWordFernet(password).encrypt(message)
