BLAKE2 is a fast and secure cryptographic hash function.
This is a pure JavaScript implementation of its BLAKE2s flavor (currently without tree mode support).
Via NPM:
$ npm install blake2s-js
Via Bower:
$ bower install blake2s-js
or just download blake2s.min.js
.
Creates a new instance of BLAKE2s hash with the given length of digest (default
and maximum 32) and an optional secret key (a Uint8Array
or Array
of
bytes).
Updates the hash with data (a Uint8Array
or Array
of bytes). starting at
the given offset
(optional, defaults to 0) and consuming the given length
(optional, defaults to the length of data
minus offset
).
Returns a Uint8Array
with the digest of consumed data. Further updates will
throw error. Repeat calls of digest()
will return the same digest.
Like digest()
, but returns a hex-encoded string.
Maximum digest length.
Block size of the hash function.
Maximum key length.
var h = new BLAKE2s(32);
h.update(new Uint8Array([1,2,3]));
h.hexDigest(); // returns string with hex digest
h.digest(); // returns Uint8Array
// Keyed:
var key = new Uint8Array(32);
window.crypto.getRandomValues(key);
var h = new BLAKE2s(32, key);
