Java Program on RSA Algorithm.RSA algorithm is an asymmetric cryptography algorithm. Asymmetric means that it works on two different keys.Algorithm & Output of the program is also given Basically you can generate a random (symmetric) encryption key and encrypt the key with RSA. Then the client could send the IV (salt, used with symmetric encryption), RSA encrypted symmetric key, encrypted data (with the symmetric encryption key) and MAC (message authentication code - hash and signature) to other side.

Is the following possible using RSA? Encrypt using PrivateKey and decrypt using PublicKey. Purpose: I need to make sure that the message came from the sender whose Public Key I have. Message content is not confidential. Is the above possible without using Message Digests? Thank you. Here's the source code which works. A Simple Blowfish Encryption / Decryption using Java.
