# sha.js
Streamable SHA hashes in pure javascript.
[](http://travis-ci.org/crypto-browserify/sha.js)
[](https://www.npmjs.org/package/sha.js)
## Example
``` js
var createHash = require('sha.js')
var sha256 = createHash('sha256')
var sha512 = createHash('sha512')
var h = sha256.update('abc', 'utf8').digest('hex')
console.log(h) //ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
//LEGACY, do not use in new systems:
var sha0 = createHash('sha')
var sha1 = createHash('sha1')
```
## supported hashes
sha.js currently implements:
* sha256
* sha512
* sha1 (legacy, no not use in new systems)
* sha (legacy, no not use in new systems)
## Note
Note, this doesn't actually implement a stream, but wrapping this in a stream is trivial.
but is does update incrementally, so you can hash things larger than ram, and also, since it reuses
the typedarrays, it uses a constant amount of memory (except when using base64 or utf8 encoding,
see code comments)
