为了更多的利益，利用单向加密算法或散列，像MD 514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.
该方案将对称加密算法、椭圆曲线公钥加密算法和单向函数有机结合，实现了用户使用权限和关键敏感字段的安全级别的关联。
Here we give a simpler implement, which encrypts the sensitive data at each level with a key unique to that level, whose security is based on elliptic curve discrete logarithm problem.
