// => keyPair.secretKey // Uint8Array

API

keyPair = new crypto.Keypair([seed])

Generates or re-create a key pair from a seed.

Seed can be a String (base58), Buffer, or Uint8Array.

Seed can have both secret and public key or just the secret key.

Returns:

{
  publicKey, // PublicKey instance
  secretKey // Uint8Array
}

validated = crypto.validateKeyPair(keyPair)

Checks if the secret key aligns with the provided public key.

isOnCurve = crypto.isOnCurve(publicKey)

Check if the address can have or not a secret key.

hash = crypto.hash(buffer)

Returns a Buffer with a SHA-256 hash.

signature = crypto.sign(message, secretKey)

Sign a message with a secret key.

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

Check if the signature was signed by the public key.
