This class represents abstract ECC public keys. When encoding a key via an encoder that can be accessed via the corresponding member functions, the key will decide upon its internally stored encoding information whether to encode itself with or without domain parameters, or using the domain parameter oid. Furthermore, a public key without domain parameters can be decoded. In that case, it cannot be used for verification until its domain parameters are set by calling the corresponding member function.
