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).
