Module message 

Signing and verification of arbitrary messages.

Messages are signed with a BIP-340 Schnorr signature over a SHA256 hash of the message bytes:

digest = SHA256( "bark/message" || message )

The hash is prefixed with a constant string to prevent collisions with other signatures.

A message can be verified either against a public key directly, or against an Ark Address.
