The javax.crypto.spec package contains classes that define transparent java.security.spec.KeySpec and java.security.spec.AlgorithmParameterSpec representations of secret keys, Diffie-Hellman public and private keys, and parameters used by various cryptographic algorithms. The classes in this package are used in conjunction with java.security.KeyFactory, javax.crypto.SecretKeyFactory and java.security.AlgorithmParameters for converting opaque Key, and AlgorithmParameters objects to and from transparent representations. In order to make good use of this package, you must be familiar with the specifications of the various cryptographic algorithms it supports and the basic mathematics that underlie those algorithms.
