Digital Signature

To create a digital signature scheme, you essentially need three functions:

Generate Keys publicKey, privateKey = GenerateKeys()

• It returns a pair of keys - public key: your identity
  • secret key (sometimes called private key): your secret
    It doesn’t take any arguments but just randomness (It has to be long enough)

Sign signature = Sign(privateKey, message)

• It takes your secret key and your message
• It returns a signature

Verify isValid = Verify(publicKey, message, signature)

• It takes a public key, a message and a signature
• It returns a boolean
