DISABLE_THIRD_PARTY_CHECK=Package needs updating with node_modules Change-Id: I889f1b86c586e37307a3e13ad762aa56d1ece150 Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/1946468 Commit-Queue: Paul Lewis <aerotwist@chromium.org> Reviewed-by: Tim van der Lippe <tvanderlippe@chromium.org>
sha.js
Node style SHA on pure JavaScript.
var shajs = require('sha.js')
console.log(shajs('sha256').update('42').digest('hex'))
// => 73475cb40a568e8da8a045ced110137e159f890ac4da883b6b17dc651b3a8049
console.log(new shajs.sha256().update('42').digest('hex'))
// => 73475cb40a568e8da8a045ced110137e159f890ac4da883b6b17dc651b3a8049
var sha256stream = shajs('sha256')
sha256stream.end('42')
console.log(sha256stream.read().toString('hex'))
// => 73475cb40a568e8da8a045ced110137e159f890ac4da883b6b17dc651b3a8049
supported hashes
sha.js currently implements:
- SHA (SHA-0) -- legacy, do not use in new systems
- SHA-1 -- legacy, do not use in new systems
- SHA-224
- SHA-256
- SHA-384
- SHA-512
Not an actual stream
Note, this doesn't actually implement a stream, but wrapping this in a stream is trivial. It does update incrementally, so you can hash things larger than RAM, as it uses a constant amount of memory (except when using base64 or utf8 encoding, see code comments).
