AES-TS

a modern port of AES-JS:

A pure JavaScript implementation of the AES block cipher algorithm and all common modes of operation (CBC, CFB, CTR, ECB and OFB).

for proper documentation please check their README.md.

motivation

• enable three shaking
  • it's rare that an app will use all this modes
  • not every app needs encryption + decryption
  • only half of the constants are needed on each direction
• a good replacement for libraries that import crypto-browserify on the browser.
• built-in typescript types

best practices

• don't roll your own crypto, especially don't touch Block directly.
• don't use ECB. don't reuse IVs.
• don't use this library, use SubtleCrypto, whenever possible.

exports

ESM exports, listed by Common Mode Of Operation.

*	Encryptor	Decryptor
Block	Encryptor	Decryptor
CBC	CBCEncryptor	CBCDecryptor
CFB	CFBEncryptor	CFBDecryptor
CTR	CTREncryptor	CTRDecryptor
ECB	ECBEncryptor	ECBDecryptor
OFB	OFBEncryptor	OFBDecryptor

interfaces

replace ___ for the mode of operation.

each mode has unique parameters, described by their types.

Encryptor

const encryptor = new ___Encryptor(key)
const ciphertext = encryptor.encrypt(plaintext)

Decryptor

const decryptor = new ___Decryptor(key)
const plaintext = decryptor.decrypt(ciphertext)

Encryptor + Decryptor

const mode = new ___(key)
const sametext = mode.decrypt(mode.encrypt(plaintext))
