Classes
struct	dev::SignatureStruct
struct	dev::CompactSignatureStruct
class	dev::KeyPair
class	dev::crypto::Nonce
	Generator for non-repeating nonce material. The Nonce class should only be used when a non-repeating nonce is required and, in its current form, not recommended for signatures. This is primarily because the key-material for signatures is encrypted on disk whereas the seed for Nonce is not. Thus, Nonce's primary intended use at this time is for networking where the key is also stored in plaintext. More...
