Sign arbitrary messages for authentication:

const result = await provider.signPersonalMessage({
  message,
})

console.log({
  signature: result.signature,   // Base64 encoded signature
  bytes: result.bytes,           // Signed message bytes
})

const message = new TextEncoder().encode('Hello, Sui!')

const result = await provider.signMessage({
  message,
})

console.log({
  signature: result.signature,
  messageBytes: result.messageBytes,
})

Verify Signature

const message = new TextEncoder().encode('Hello, Sui!')
const { signature } = await provider.signPersonalMessage({ message })

const accounts = await provider.getAccounts()
const publicKey = accounts[0].publicKey

const isValid = await verifyPersonalMessage(message, signature)
console.log('Signature valid:', isValid)
