generateKeys(seed: Uint8Array): null | { secretKey: Uint8Array; publicKey: Uint8Array; }

Generates a curve 25519 keypair.

seed is a 32 byte cryptographic secure random array. This is basically the secret key Returns an object containing a secret and public key as 32 byte typed arrays

scalarMult(secretKey: Uint8Array, publicKey: Uint8Array): Uint8Array

Generates the common key as the produkt of secretKey1 * publicKey2.

secretKey must be a 32 byte secret key of pair 1 publicKey must be a 32 byte public key of pair 2 Returns secretKey * publicKey

selftest(): boolean
