Pure javascript implementation of BLAKE3

Usage

const blake = require("blake3-js");

blake
  .newRegular()
  .update([0,1,2,3,4,5,6])
  .finalize();

blake
  .newKeyed("whats the Elvish word for friend")
  .update("input can be in be in text form as well")
  .finalize();

blake
  .newDeriveKey("BLAKE3 2019-12-27 16:29:52 test vectors context")
  .update([0])
  .finalize();

Note: In keyed mode the key has to be exactly 32 bytes. Accepts both an ASCII string of 32 bytes or a byte array of length 32.

Tests

Test vectors from the reference implementation have been used. Run yarn test to run the test suite.

Limitations

• Performance is bad, many opportunities to improve this. (Will switch to typed arrays for the u32 data type which should improve this a bit)
• UTF-8 support is WIP
