RSA algorithm is the most famous public cryptosystem. Based on the difficulty of large integer. Its public key and private key is a function of large prime numbers, from a public key and the ciphertext to recover the plaintext of the difficulty is equivalent to decompose the product of two large prime numbers. Algorithm process: first is to design the key, then encrypt the message, and finally to decrypt the ciphertext.
