Java Cryptography Extension
Encyclopedia
The Java Cryptography Extension (JCE) is an officially released Standard Extension to the Java Platform. JCE provides a framework and implementation for encryption
, key generation
and key agreement, and Message Authentication Code
(MAC) algorithms. JCE supplements the Java platform, which already includes interfaces and implementations of message digests and digital signature

Encryption
In cryptography, encryption is the process of transforming information using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information...

Key generation
Key generation is the process of generating keys for cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted....
and key agreement, and Message Authentication Code
Message authentication code
In cryptography, a message authentication code is a short piece of information used to authenticate a message.A MAC algorithm, sometimes called a keyed hash function, accepts as input a secret key and an arbitrary-length message to be authenticated, and outputs a MAC...

Digital signature
A digital signature or digital signature scheme is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, and that it was not altered in transit...
