As its name implies, the
java.security.interfaces package contains only
interfaces. These interfaces define methods that provide
algorithm-specific information (such as key values and initialization
parameter values) about DSA, RSA, and EC public and private keys. If
you are using the RSA algorithm, for example, and working with a
java.security.PublicKey object, you can cast that
PublicKey to an RSAPublicKey
object and use the RSA-specific methods defined by
RSAPublicKey to query the key value directly.The java.security.interfaces package was
introduced in Java 1.1. As of Java 1.2, the
java.security.spec package is the preferred way
for obtaining algorithm-specific information about keys and algorithm
parameters. This package remains useful in Java 1.2 and later,
however, for identifying the type of a given
PublicKey or PrivateKey object.The interfaces in this package are typically of interest only to
programmers who are implementing a security provider or who want to
implement cryptographic algorithms themselves. Use of this package
typically requires some familiarity with the mathematics underlying
DSA and RSA public-key cryptography.
