为了更多的利益，利用单向加密算法或散列，像MD 5 14或Blowfish, 15将使密码的解密成为不可能。

For added benefit, using a one-way encryption algorithm or hash, like MD5 14 or Blowfish, 15 will make decrypting the password impossible.

MD 5就是采用单向加密的加密算法，所谓单向加密就是只能对数据进行加密，也就是说，没有办法对加密以后的数据进行解密。

MD5 encryption is one-way encryption algorithm, the so-called one-way encryption is only for data encryption, In other words, there is no way to encrypt the data after decryption.

在简化pki系统的研究中，本文首先介绍基于身份的加密算法，然后结合单向哈希链，提出一种基于IBE的改进PKI系统。

In the research of simplifying PKI system, this paper proposes an improved PKI system based on the combine of the IBE and the one-way hash chain.
