RSA (Rivest-Shamir-Adleman) is a public-key encryption algorithm with a typical key size of 1,024 to 4,096 bits. 2 large primes are required to generate the keys. AES (Advanced Encryption Standard) is based on Rijndael, secret-key encryption algorithm using a block cipher with key sizes of 128, 192, or 256 bits. Simple Encrypt will take a text file, generate keys and then encrypt it. The output is the ciphertext and keys. Note: Realistically, I will keep the algorithms simple(r) by having key sizes of 32 bits! Hopefully, I'll get round to developing a reasonably efficient class for larger numbers, but until then I am restricted.

In distributed cryptosystem a secret key is distributed among the participants of the system, in the way that only a group of some authorized users can perform any actions related to the secret key. A secret key is used to encrypt a session key, create a digital signature and to certify public keys. The system uses symetric encryption algorithm with a session key to encrypt messages. Shoup’s threshold signature scheme has been used for cooperative signing and also for cooperative decryption.
