Method Detail

checkPrivateKeyback to summary
public static ECPrivateKey checkPrivateKey(ECPrivateKey prv) throws InvalidKeyException

Check an ECPrivateKey to make sure the scalar value is within the range of the order [1, n-1].

Parameters
prv:ECPrivateKey

the private key to be checked.

Returns:ECPrivateKey

the private key that was evaluated.

Exceptions
InvalidKeyException:
if the key's scalar value is not within the range 1 <= x < n where n is the order of the generator.
