Java in a Nutshell, 5th Edition [Electronic resources]

The java.security.spec package contains classes that define transparent representations for DSA, RSA, and EC public and private keys and for X.509 and PKCS#8 encodings of those keys. It also defines a transparent representation for DSA algorithm parameters. The classes in this package are used in conjunction with java.security.KeyFactory and java.security.AlgorithmParameters for converting opaque Key and AlgorithmParameters objects to and from transparent representations.

This package is not frequently used. To make use of it, you must be somewhat familiar with the mathematics that underlies DSA and RSA public-key encryption and the encoding standards that specify how keys are encoded as byte streams.
