Chapter 17. javax.crypto and Subpackages
This
chapter documents the cryptographic features (including encryption
and decryption) of the javax.crypto package and
its subpackages. These packages were originally part of the Java
Cryptography Extension (JCE) before being integrated into Java 1.4,
which is why they have the "javax"
extension prefix. All of the commonly-used cryptography classes are
in the javax.crypto package itself. The
javax.crypto.interfaces subpackage defines
algorithm-specific interfaces for certain type of cryptographic keys.
The javax.crypto.spec subpackage defines classes
that provide a transparent, portable, and provider-independent
representation of cryptographic keys and related objects. |
