Dec 03, 2016 AES 256bit Encryption/Decryption and storing in the. And supports a block length of 128bits and key lengths of 128,192 and 256 bits. AES-256 encryption/decryption using Java. Java support many secure encryption algorithms but some of them are weak to be used in security-intensive applications. For example, the Data Encryption Standard (DES) encryption algorithm is considered highly insecure; messages encrypted using DES have been decrypted by brute force within a single day by machines such as the Electronic Frontier Foundation’s (EFF) Deep. Key generators are constructed using one of the getInstance class methods of this class. KeyGenerator objects are reusable, i.e., after a key has been generated, the same KeyGenerator object can be re-used to generate further keys. There are two ways to generate a key: in an algorithm-independent manner, and in an algorithm-specific manner.

KeyGenerator objects are reusable, i.e., after a key has been generated, the same KeyGenerator object can be re-used to generate further keys.
There are two ways to generate a key: in an algorithm-independent manner, and in an algorithm-specific manner. The only difference between the two is the initialization of the object:

In case the client does not explicitly initialize the KeyGenerator (via a call to an
init method), each provider must supply (and document) a default initialization.
Every implementation of the Java platform is required to support the following standard
KeyGenerator algorithms with the keysizes in parentheses:
