# sha.js
Streamable SHA1 hash in pure javascript.
[](http://travis-ci.org/dominictarr/sha.js)
[](https://ci.testling.com/dominictarr/sha.js)
## Example
``` js
var createHash = require('sha.js')
var sha1 = createHash('sha1')
var sha256 = createHash('sha256')
var sha512 = createHash'sha512')
var h = sha1.update('abc', 'utf8').digest('hex')
console.log(h) //a9993e364706816aba3e25717850c26c9cd0d89d
```
## supported hashes
sha.js currently implements:
* sha1
* sha256
* sha512
## 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)
