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).
