Encryption and decryption are fundamental requirements of every secure-aware application, therefore the Java platform provides strong support for encryption and decryption through its Java Cryptographic Extension (JCE) framework which implements the standard cryptographic algorithms such as AES, DES, DESede and RSA. This tutorial shows you how to basically encrypt and decrypt files using the Advanced Encryption Standard (AES) algorithm. AES is a symmetric-key algorithm that uses the same key for both encryption and decryption of data.

RSA

The RSA cryptosystem is a public-key cryptosystem that offers both encryption and digital signatures (authentication). Ronald Rivest, Adi Shamir, and Leonard Adleman developed the RSA system in 1977 .RSA stands for the first letter in each of its inventors' last names.

The RSA algorithm works as follows: take two large primes, p and q, and compute their product n = pq; n is called the modulus. Choose a number, e, less than n and relatively prime to (p-1)(q-1), which means e and (p-1)(q-1) have no common factors except 1. Find another numb ....etc
