WebThe first example below will illustrate a simple password-based AES encryption (PBKDF2 + AES-CTR) without message authentication (unauthenticated encryption).The next example will add message authentication (using the AES-GCM mode), then will add password to key derivation (AES-256-GCM + Scrypt). WebFeb 24, 2024 · Now CTR or counter mode is a way to chain together blocks encrypted with a so-called block cipher. Block ciphers (like AES or Serpent, for example) only produce a good encryption for a very small size of data, a block. They are usually heavily optimized for working with today's computers and are perfect to use with large amounts of data, though.
