Functions
std::vector< uint8_t >	sign (std::vector< uint8_t > const &message, private_signing_key const &priv, bool include_message=true)
	Returns the message with the signature appended, created using the passed private key.
std::vector< uint8_t >	sign (std::string_view const &message, private_signing_key const &priv, bool include_message=true)
std::vector< uint8_t >	sign (uint8_t const *message, size_t const size, private_signing_key const &priv, bool include_message=true)
bool	verify (std::vector< uint8_t > const &message, public_verification_key const &pub)
	Verify a message with attached signature. Returns true iff it has been signed by the private key corresponding to the passed public key.
bool	verify (std::string_view const &message, public_verification_key const &pub)
bool	verify (uint8_t const *message, size_t const size, public_verification_key const &pub)
bool	verify (std::vector< uint8_t > const &message, std::vector< uint8_t > const &signature, public_verification_key const &pub)
	Verify a message with detached signature. Returns true iff it has been signed by the private key corresponding to the passed public key.
bool	verify (std::string_view const &message, std::string_view const &signature, public_verification_key const &pub)
bool	verify (uint8_t const *message, size_t const message_size, uint8_t const *signature, size_t const sig_size, public_verification_key const &pub)
