All Implemented Interfaces:

Algorithm, EncryptionAlgorithm

public class RSA
extends AsymmetricAlgorithm

RSA contains functions for encrypting and decrypting using the RSA algorithm. The encryption mode is set to 'NONE'. The padding is set to 'OAEP'. This classes defaults to a key creation length of 2048 bits.
