| Method Detail |
public static byte[] generateSharedSecret(ECPrivateKey localPrivateKey, ECPublicKey remotePublicKey, boolean useCofactor) throws InvalidCryptoSystemException, CryptoTokenException, CryptoUnsupportedOperationException
localPrivateKey - The local private key to use.remotePublicKey - The remote public key to use.useCofactor - If true, the cofactor of the elliptic curve is used in the calculations.
If false, it is not used. Note, setting this value to TRUE is the most common usage.InvalidCryptoSystemException - Thrown if the local crypto system
is different than the remote crypto systemCryptoTokenException - Thrown if an error occurs with the crypto
token or the crypto token is invalid.CryptoUnsupportedOperationException - Thrown if a call is made to
an unsupported operation.Certicom Contact Information
