ECPublicKey

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.

algoName string algoName [@property getter]: Get the name of the underlying public key scheme.
estimatedStrength size_t estimatedStrength(): Return the estimated strength of the underlying key against the best currently known attack. Note that this ignores anything but pure attacks against the key itself and do not take into account padding schemes, usage mistakes, etc which might reduce the strength. However it does suffice to provide an upper bound.
getOid OID getOid(): Get the OID of the underlying public key scheme.
checkKey bool checkKey(RandomNumberGenerator rng, bool strong): Test the key values for consistency.
messageParts size_t messageParts(): Find out the number of message parts supported by this scheme.
messagePartSize size_t messagePartSize(): Find out the message part size supported by this scheme/key.
maxInputBits size_t maxInputBits(): Get the maximum message size in bits supported by this public key.
algorithmIdentifier AlgorithmIdentifier algorithmIdentifier()
x509SubjectPublicKey Vector!ubyte x509SubjectPublicKey()
loadCheck void loadCheck(RandomNumberGenerator rng): Self-test after loading a key
