The crypto primitives used in hypercore, extracted into a separate module

npm install hypercore-crypto

const crypto = require('hypercore-crypto')

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

Returns an ED25519 keypair that can used for tree signing.

Signs a message (buffer).

Verifies a signature for a message.

Hashes a leaf node in a merkle tree.

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

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

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

Returns a buffer containing random bytes of size size.

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