浅谈数据加密技术

数据加密技术是最基本的网络安全技术。它通过诸如改造和更换各种手段将被保护信息换成密文的信息，然后存储或传输，以达到保护信息的目的。根据其类型的不同，密码技术可分为两类：对称加密算法（私钥加密）和非对称加密算法（公钥加密）。现在多采用两种算法的结合。

Of Data Encryption Technology

Data encryption is the most basic network security technology. It does this by various means, such as rehabilitation and replacement of the information will be protected information into ciphertext, and then stored or transmitted, in order to achieve the purpose of protecting information. According to their type, the encryption can be divided into two categories： symmetric encryption algorithm （private key） and asymmetric encryption algorithm （public key encryption）. Now the combination of the two algorithms to use more.
