 1 | # aes-wasm
 2 | 
 3 | This library is a WASM port of the [ghostscript AES implementation](https://www.ghostscript.com/doc/base/aes.c).
 4 | Currently CBC and CTR mode are supported.
 5 | 
 6 | An [explanatory blog article](https://www.inovex.de/blog/webassembly-production/) is published on the inovex blog.
 7 | 
 8 | You can use this library like any other JS dependency in your project by running
 9 | ```sh
10 | npm i aes-wasm
11 | ```
12 | or
13 | ```sh
14 | yarn add aes-wasm
15 | ```
16 | 
17 | and importing it in the appropriate place in your project:
18 | ```
19 | import { aes256 } from 'aes-wasm';
20 | ```
21 | 
22 | The WebAssembly code is inlined into a common JS bundle and compiled and executed on the fly.
23 | A webpack build can handle this just fine, but the browser running your application has to [support](https://caniuse.com/#feat=wasm)
24 | WebAssembly.
25 | 
26 | ## Usage
27 | 
28 | This library has three exports - `aes128`, `aes192` and `aes256`.
29 | All function exactly the same but use the three variants of AES with different key sizes under the hood which means
30 | they have to be initialized with appropriate keys.
31 | 
32 | Each export of the module is a nullary function which returns a promise that resolves with an API object.
33 | Calling this function initializes a new WebAssembly context.
34 | 
35 | ```js
36 | import { aes256 } from 'aes-wasm';
37 | 
38 | aes256().then(aesApi => {
39 |     // encrypt and decrypt here
40 | });
41 | ```
42 | 
43 | The API object has three functions for initialization, encryption and decryption:
44 | 
45 | ### init(key, iv, mode = 'CBC')
46 | 
47 | Initializes the instance with a key and an IV. The `key` has to be a `TypedArray`, an `Array` or an array-like object
48 | containing the byte values of the AES key (16 items for aes128, 24 items for aes192 and 32 items for aes256).
49 | 
50 | The `iv` has to be a `TypedArray`, an `Array` or an array-like object containing the byte values of the AES IV (16 items).
51 | 
52 | `mode` defines the encryption/decryption mode as `string` - supported values are `CBC` and `CTR`.
53 | 
54 | ### encrypt(plainData): encryptedData
55 | 
56 | Encrypts a given set of data which has to be a `TypedArray`, an `Array` or an array-like object containing the byte values
57 | of the data block. The size of the data block has to be divisble by 16 if the `CBC` mode is used (padding is not included yet).
58 | A `TypedArray` will yield the best performance as it doesn't have to be converted prior to use.
59 | Returns a `TypedArray` containing the encrypted data.
60 | 
61 | ### decrypt(encryptedData): plainData
62 | 
63 | Decrypts a given set of encrypted data which has to be a `TypedArray`, an `Array` or an array-like object containing the byte values
64 | of the data block. The size of the data block has to be divisble by 16 if the `CBC` mode is used (padding is not included yet).
65 | A `TypedArray` will yield the best performance as it doesn't have to be converted prior to use.
66 | Returns a `TypedArray` containing the decrypted data.
