GenerateKey generates a public/private key pair using entropy from rand.

NewDerivedKeyFromSeed calculates a private key from a 32 bytes random seed, an integer index and salt.

Sign signs the message with privateKey and returns a signature.

Sign2 signs the message with privateKey and returns a signature.

Verify reports whether sig is a valid signature of message by publicKey.

Verify2 verifies a signature created with Sign2(), assuming the verifier possesses the public key.
