Several technologies exist for encryption, such as symmetrickeycryptography and asymmetric key cryptography.
目前有几种加密技术如对称密钥密码系统和非对称密钥密码系统。

The public keycryptography can just solve these problems, but it is much slower than the symmetrickeycryptography.
而公钥密码算法正好可以解决这方面的问题,但在速度上远远不及对称密码算法。

A symmetric algorithm requires that both the sender and receiver of the message use the same secret key; this is often referred to as secret key cryptography.
