# Functions
GenerateKey generates a public/private key pair using entropy from rand.
NewKeyFromSeed calculates a private key from a seed.
Scheme returns a signature interface.
Sign signs the message with privateKey and returns a signature.
SignPh creates a signature of a message given a keypair.
Verify returns true if the signature is valid.
VerifyAny returns true if the signature is valid.
VerifyPh returns true if the signature is valid.
