Cryptographic signatures made easy, with some polymorphism. More coming soon.
npm install --save kelso
const { EthereumEntity } = require('kelso')
// Alice can sign *and* verify
const alice = new EthereumEntity('<some-mnemonic-string>', 'mnemonic')
// Bob can only verify (unless he loads a private key later)
const bob = new EthereumEntity()
// Have Alice sign a message
const signatureString = await alice.signMessageString('hi')
// Have Bob verify it
const [isValidSignature, recoveredAddress] = await bob.verifySignatureString(
'hi',
signatureString
)
// Bob makes sure that alice actually signed it
if (isValidSignature && recoveredAddress === alice.getAddress()) {
console.log('Alice signed a message for Bob!')
