Description

The documentation should state if nacl.signing.SigningKey and VerifyKey objects can be used to sign/verify several messages with a keypair. Or does one need to create a new object for every message (like hmac and hashlib of the python standard library)?

From my testing it looks like one can reuse these object. Is this guaranteed in the future or just an deail of the current implementation?
