const hash = sha512()
Create a new hash instance.
Update the hash with a new piece of data.
data may be passed as a buffer, uint8array or a string. If
data is passed as a string, then it will be interpreted as a
utf8 string unless
enc specifies an encoding.
Digest the hash. If
enc is specified, then the digest shall be returned as an
enc encoded string. Otherwise a buffer is returned.
var promise = sha512.ready([cb])
Wait for the WASM code to load. Returns the WebAssembly instance promise as well for convenience. You have to call this at least once before instantiating the hash.
The bulk of this module is implemented in WebAssembly in the sha512.wat file. The format of this file is S-Expressions that can be compiled to their binary WASM representation by doing
wat2wasm sha512.wat -o sha512.wasm
# also available as `npm run compile` wat2js sha512.wat -o sha512.js
If you do not have
wat2wasm installed follow the instructions here, https://github.com/WebAssembly/wabt
