```
It can also be used directly from HTML (via [jsDelivr](https://www.jsdelivr.com/package/npm/hash-wasm)):
```html
<!-- load all algortihms into the global `hashwasm` variable -->
<script src="https://cdn.jsdelivr.net/npm/hash-wasm@4"></script>
<!-- load individual algortihms into the global `hashwasm` variable -->
<script src="https://cdn.jsdelivr.net/npm/hash-wasm@4/dist/md5.umd.min.js"></script>

### Usage with the shorthand form
It is the easiest and the fastest way to calculate hashes. Use it when the input buffer is already in the memory.
```javascript
import { md5, sha1, sha512, sha3 } from 'hash-wasm';
async function run() {
console.log('MD5:', await md5('demo'));
const int8Buffer = new Uint8Array([0, 1, 2, 3]);
console.log('SHA1:', await sha1(int8Buffer));
console.log('SHA512:', await sha512(int8Buffer));
const int32Buffer = new Uint32Array([1056, 641]);
console.log('SHA3-256:', await sha3(int32Buffer, 256));
}
run();
```

*\*\* See [API reference](#api)*
### Advanced usage with streaming input
createXXXX() functions create new WASM instances with separate states, which can be used to calculate multiple hashes paralelly. They are slower compared to shorthand functions like md5(), which reuse the same WASM instance and state to do multiple calculations. For this reason, the shorthand form is always preferred when the data is already in the memory.
For the best performance, avoid calling createXXXX() functions in loops. When calculating multiple hashes sequentially, the init() function can be used to reset the internal state between runs. It is faster than creating new instances with createXXXX().
```javascript
import { createSHA1 } from 'hash-wasm';
async function run() {
const sha1 = await createSHA1();
sha1.init();
while (hasMoreData()) {
const chunk = readChunk();
sha1.update(chunk);
}
const hash = sha1.digest('binary'); // returns Uint8Array
console.log('SHA1:', hash);
}
run();
```

### Hashing passwords with Argon2
The recommended process for choosing the parameters can be found here: https://tools.ietf.org/html/draft-irtf-cfrg-argon2-04#section-4
```javascript
import { argon2id, argon2Verify } from 'hash-wasm';
async function run() {
const salt = new Uint8Array(16);
window.crypto.getRandomValues(salt);
const key = await argon2id({
password: 'pass',
salt, // salt is a buffer containing random bytes
parallelism: 1,
iterations: 256,
memorySize: 512, // use 512KB memory
hashLength: 32, // output size = 32 bytes
outputType: 'encoded', // return standard encoded string containing parameters needed to verify the key
});
console.log('Derived key:', key);
const isValid = await argon2Verify({
password: 'pass',
hash: key,
});
console.log(isValid ? 'Valid password' : 'Invalid password');
}
run();
```
*\* See [String encoding pitfalls](#string-encoding-pitfalls)*
*\*\* See [API reference](#api)*
### Hashing passwords with bcrypt
```javascript
import { bcrypt, bcryptVerify } from 'hash-wasm';
async function run() {
const salt = new Uint8Array(16);
window.crypto.getRandomValues(salt);
const key = await bcrypt({
password: 'pass',
salt, // salt is a buffer containing 16 random bytes
costFactor: 11,
outputType: 'encoded', // return standard encoded string containing parameters needed to verify the key
});
console.log('Derived key:', key);
const isValid = await bcryptVerify({
password: 'pass',
hash: key,
});
console.log(isValid ? 'Valid password' : 'Invalid password');
}
run();
```
*\* See [String encoding pitfalls](#string-encoding-pitfalls)*
*\*\* See [API reference](#api)*
### Calculating HMAC
All supported hash functions can be used to calculate HMAC. For the best performance, avoid calling createXXXX() in loops (see `Advanced usage with streaming input` section above)
```javascript
import { createHMAC, createSHA3 } from 'hash-wasm';
async function run() {
const hashFunc = createSHA3(224); // SHA3-224
const hmac = await createHMAC(hashFunc, 'key');
const fruits = ['apple', 'raspberry', 'watermelon'];
console.log('Input:', fruits);
const codes = fruits.map(data => {
hmac.init();
hmac.update(data);
return hmac.digest();
});
console.log('HMAC:', codes);
}
run();
```
*\* See [String encoding pitfalls](#string-encoding-pitfalls)*
*\*\* See [API reference](#api)*
### Calculating PBKDF2
All supported hash functions can be used to calculate PBKDF2. For the best performance, avoid calling createXXXX() in loops (see `Advanced usage with streaming input` section above)
```javascript
import { pbkdf2, createSHA1 } from 'hash-wasm';
async function run() {
const salt = new Uint8Array(16);
window.crypto.getRandomValues(salt);
const key = await pbkdf2({
password: 'password',
salt,
iterations: 1000,
hashLength: 32,
hashFunction: createSHA1(),
outputType: 'hex',
});
console.log('Derived key:', key);
}
run();
```
*\* See [String encoding pitfalls](#string-encoding-pitfalls)*
*\*\* See [API reference](#api)*
### String encoding pitfalls
You should be aware that there may be multiple UTF-8 representations of a given string:
```js
'\u00fc' // encodes the ü character
'u\u0308' // also encodes the ü character
'\u00fc' === 'u\u0308' // false
'ü' === 'ü' // false
```
All algorithms defined in this library depend on the binary representation of the input string. Thus, it's highly recommended to normalize your strings before passing it to hash-wasm. You can use the `normalize()` built-in String function to archive this:
```js
'\u00fc'.normalize() === 'u\u0308'.normalize() // true
const te = new TextEncoder();
te.encode('u\u0308'); // Uint8Array(3) [117, 204, 136]
te.encode('\u00fc'); // Uint8Array(2) [195, 188]
te.encode('u\u0308'.normalize('NFKC')); // Uint8Array(2) [195, 188]
te.encode('\u00fc'.normalize('NFKC')); // Uint8Array(2) [195, 188]
```
You can read more about this issue here: https://en.wikipedia.org/wiki/Unicode_equivalence
### Resumable hashing
You can save the current internal state of the hash using the `.save()` function. This state may be written to disk or stored elsewhere in memory.
You can then use the `.load(state)` function to reload that state into a new instance of the hash, or back into the same instance.
This allows you to span the work of hashing a file across multiple processes (e.g. in environments with limited execution times like AWS Lambda, where large jobs need to be split across multiple invocations), or rewind the hash to an earlier point in the stream. For example, the first process could:
```js
// first process starts hashing
const md5 = await createMD5();
md5.init();
md5.update("Hello, ");
const state = md5.save(); // save this state
// second process resumes hashing from the stored state
const md5 = await createMD5();
md5.load(state);
md5.update("world!");
console.log(md5.digest()); // Prints 6cd3556deb0da54bca060b4c39479839 = md5("Hello, world!")
```
*Note that both the saving and loading processes must be running compatible versions of the hash function (i.e. the hash function hasn't changed between the versions of hash-wasm used in the saving and loading processes). If the saved state is incompatible, `load()` will throw an exception.*
*The saved state can contain information about the input, including plaintext input bytes, so from a security perspective it must be treated with the same care as the input data itself.*

Future plans
=====
- Add more well-known algorithms
- Write a polyfill which keeps bundle sizes low and enables running binaries containing newer WASM instructions
- Use WebAssembly Bulk Memory Operations
- Use WebAssembly SIMD instructions (expecting a 10-20% performance increase)
- Enable multithreading where it's possible (like at Argon2)
