Data encryption is currently divided into two types of Symmetric encryption with Asymmetric encryption, encryption, both types are suitable for different applications. Where before they show the difference of these two types of encryption. Users should be aware of the process of encryption, Symmetric encryption is both the first data encryption using the same Secret key to encrypt and decrypt data by sending the information to send the Secret key through a stable, secure information. If the Secret key is capturing between by people of ill will to be decrypted Symmetric encryption Algorithm that is immediate: DES, 3DES, AES, Blowfish, IDEA, RC, etc.
