Generate a SecretKey from the underlying KeyAgreement, ensuring that the result key is no larger than the maximum key length, using the hashAlgorithm this object was created with if necessary.

Parameters:

maximumKeyLength - The largest possible acceptable key length this method should generate

pk - The local private key

remoteKey - The remote key to complete the agreement

Returns:

A SecretKey no longer than maximumKeyLength

Throws:

NoSuchAlgorithmException
