expansion that Java Cryptography Extension, referred to JCE. It is Sun's encryption software, including encryption and key generation functions. JCE is JCA (Java Cryptography Architecture), an extension. JCE no specific encryption algorithms, but provides a framework, the specific encryption algorithm can achieve as a service provider to join. Apart from the JCE framework, JCE package also includes SunJCE service providers, including many useful encryption algorithms such as DES (Data Encryption Standard) and the Blowfish. For simple terms, in this paper we will use DES encryption and decryption algorithms byte code. Below is JCE encryption and decryption of data must adhere to the basic steps : Step 1 : Generating a security keys. In any encryption or decryption of data is needed befo
