Rijndael algorithms are as new Advanced Encryption Standard (AES--Advanced Encryption Standard).
Asymmetric encryption provides a very safe method for the encryption of data with decryption, it has used a pair of close
Key, public key (public key) and private key (private key).Private key can only be by side's safekeeping, it is impossible to leaks, and public key
Any its people of request can then be issued.Asymmetric encryption is encrypted one in key using this, and decrypting then needs
Another key.For example you ask public key to bank, public key is issued you by bank, you are using public key to message encryption, then only
There is the holder of private key -- bank could decrypt your message.Unlike symmetric cryptography, private key need not be led in bank
Cross network to send, therefore security greatly improves.Current most common rivest, shamir, adelman is RSA Algorithm.
