Is your feature request related to a problem? Please describe.
Substrate uses SR25519

Describe the solution you'd like
Implement sr25519 algorithm against the the PublicKey and PrivateKey interfaces

// PrivateKey definition usable in all mailchain crypto operations
type PrivateKey interface {
	// Bytes returns the byte representation of the private key
	Bytes() []byte
	// PublicKey from the PrivateKey
	PublicKey() PublicKey
        Sign(message []byte) (signature []byte, err error)
}

// PublicKey definition usable in all mailchain crypto operations
type PublicKey interface {
	// Bytes returns the byte representation of the public key
	Bytes() []byte
        Verify(data []byte) error
}
