Node Stream wrapper for Blake2b
Usage
var blakeb2Stream = processstdin
API
var stream = blakeb2Stream([opts], cb(err, hash))
Create a stream that calculates the Blake2b hash when .end()
ed. opts
include
opts.outputLength
for the byte length of the hash and opts.key
if you want
to partition your hash space with a custom key. opts.key
must be buffer. The
allowed ranges for either argument can be referenced by the constants below.
When the source stream ends cb
will be called with a Buffer
of length
opts.outputLenght
(which defaults to blake2bStream.BYTES
/ 32 bytes)
