@omegajs/crypto v1.0.0

@omegajs/crypto

The basic cryptographic elements utilized in oScrolls have been isolated into a distinct module.

Install Via L1FE's NPM

npm config set registry https://npm.l1fe.tech
npm install @omegajs/crypto

Install Via L1FE's Git Repository

git clone https://lab.l1fe.tech/omega/crypto.git
cd crypto
npm install

Usage

const crypto = require('@omegajs/crypto')

const keyPair = crypto.keyPair()
console.log(keyPair) // prints a ed25519 keypair

API

keyPair = crypto.keyPair()

Returns an ED25519 keypair that can used for tree signing.

signature = crypto.sign(message, secretKey)

Signs a message (buffer).

verified = crypto.verify(message, signature, publicKey)

Verifies a signature for a message.

hash = crypto.data(data)

Hashes a leaf node in a merkle tree.

hash = crypto.parent(left, right)

Hash a parent node in a merkle tree. left and right should look like this:

{
  index: treeIndex,
  hash: hashOfThisNode,
  size: byteSizeOfThisTree
}

hash = crypto.tree(peaks)

Hashes the merkle root of the tree. peaks should be an array of the peaks of the tree and should look like above.

buffer = crypto.randomBytes(size)

Returns a buffer containing random bytes of size size.

hash = crypto.discoveryKey(publicKey)

Return a hash derived from a publicKey that can used for discovery without disclosing the public key.

list = crypto.namespace(name, count)

Make a list of namespaces from a specific publicly known name. Use this to namespace capabilities or hashes / signatures across algorithms.
