Streamable SHA hashes in pure javascript.
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')
sha.js currently implements:
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)

First-pass at JavaScript client SDK. JavaScript requires Node with Gulp to "browserfy" the library. It's the easiest way I found to use the swagger-js project; bundle up a wrapping method. There is no JavaScript reference guide. The swagger-js doesn't really document what they do very well, actually. Overall I'm not particularly impressed by swagger-js, it was hard to even figure out what the right method syntax was. We may want to invest time in doing it better. This required setting CORS response headers, which are currently defaulted to a fairly insecure setting. |
