Method Detail

isSupported

boolean isSupported(CryptoSystem cryptoSystem,
                    int operation)

Indicates whether the chosen operation is supported by this CryptoToken using the provided CryptoSytem.

Parameters:

cryptoSystem - The CryptoSystem to check against.

operation - An integer, either KEY_GENERATION, PUBLIC_KEY_OPERATION, PRIVATE_KEY_OPERATION, or some other value specific to the cryptosystem that indicates the operation to be checked.
