java.security package (and its subpackages).
The first release of Java Security in JDK 1.1 contains a subset
of cryptography functionality, including APIs for
digital signatures
and message digests.
In addition, there are abstract interfaces
for key
management and
certificate
management.The lessons in this trail describe and show you how to use the main aspects of the Java Security API.
You will learn the definitions of various cryptography terms, and see an overview of the Java Security API and its core classes. You will then learn how to produce "digital signatures" for data, and how to verify the authenticity of such signatures.
WARNING!: The Java Security API in JDK 1.1 is incomplete and will change in future releases. For example, it is not possible to import or export public or private keys used to generate and verify digital signatures. Support for specific certificate formats is also not available. Use the JDK 1.1 Java Security API interfaces and classes at your own risk and in full knowledge that some will be modified, expanded, replaced, or eliminated in future releases.For information about implementing your own security manager in JDK 1.1, refer to Providing Your Own Security Manager
.
For information about the security features available in JDK 1.2, see Security in Java 2 SDK 1.2
Java Security API Overview
provides an overview of the Java Security API. It also includes
definitions of important terms, such as "digital signature,"
"public key," and "private key," and an indication
of their use.
Using the Security API to Generate and Verify a Signature
walks you step by step through an example of writing a Java
program using the Security API to generate a digital signature
for data and to verify the authenticity of the signature.
