After losing ...Do not encrypt/decrypt passwords, that is a significant security vulnerability. HASH passwords, using a strong hash algorithm such as PBKDF2, bcrypt, scrypts, or Argon. When the user sets their password, hash it, and store the hash (and salt). In this simple encryption method, only one secret key is used to both cipher and decipher information. While the oldest and best-known encryption technique, the main drawback is that both parties need to have the key used to encrypt the data before they can decrypt it. Symmetric encryption algorithms include AES-128, AES-192, and AES-256. AES is a symmetric encryption, meaning the same key (password or passphrase) is used for encrypting and decrypting data. Step 1: Generate the key – a secret passphrase to encrypt or decrypt data. This should be kept safe because anyone with this key can decrypt your data. Step 2: Generate a cipher – an algorithm is used to perform ...
