Abstract. We previously mentioned a second type of encryption called asymmetric key (or public/private key) cryptography. This is much more recent than symmetric key, and involves some complex math. It is far slower than symmetric key, hence not suitable for encryption of large documents (normally it only encrypts 128 to 512 bits).In an asymmetric cryptographic process one key is used to encipher the data, and a different but corresponding key is used to decipher the data. A system that uses this type of process is known as a public key system. The key that is used to encipher the data is widely known, but the corresponding key for deciphering the data is a secret.Asymmetric encryption, or public key cryptography, uses a public key and a private key.
