The first chapter of this paper explains the development of cryptography, tradition cryptogram, Public Key Cryptosystem and the future of cryptography.

第一章就密码学的发展，古典密码及公开密钥技术进行说明，并对未来密码系统的发展进行了展望。

This dissertation implements an Access VPN cryptographical system and illustrates an application example.

本文在对各项技术讨论和改进的基础上，采用Kerberos协议、SOCKS协议和国内专用密码算法，实现了一个远程访问VPN密码系统，并给出了该密码系统的实际应用。

Based on these, we construct a class of nonlinear sequence generators, show that they have better cryptographical properties, and furthermore they can resist on the attack of cipher by cryptology analysis So they can be used as key sequence generators..

在此基础上自主设计了一类非线性序列生成器，证明了其具有良好的密码学性质，并且通过密码分析，表明它能抵抗现有的几种密码攻击，因此这类非线性序列适于做密钥流生成器。

Encryption Algorithm simple description : DES is a block cipher algorithm, his 64 for a pair of data encryption Encryption algorithm principle :The password system may divide into 2 big kinds from the principle, namely single key password system and double key password system.

加密算法的简单描述：DES是一种分组加密算法，他以64位为分组对数据加密。加密算法的原理：密码体制从原理上可分为2大类，即单钥密码体制和双钥密码体制。

Enter old password, Enter new password, Repeat new password It is now possible to modify and add new categories, in Settings a new category Categories can be added.

输入旧密码，输入新密码，重复新密码）现在可以修改和添加新的类别，设定一个新的类别都可以添加。

The invention relates to a code device, which is characterized in that: the device safety storage section has a blank mark which comprises at least two conditions as effective and ineffective; when the blank mark is effective, the code device only can be logged in by the device initial user; and when it is ineffective, the code device can be logged in by other user without the initial user.

本发明提供一种密码设备，其特征在于：在设备安全存储区内设置一空白标志，该空白标志至少具有有效及无效两种状态，当空白标志有效时，密码设备只接受设备初始用户的登录，当空白标志无效时，密码设备不接受设备初始用户的登录，其它用户可以正常登录。

Even though functions that create hashed passwords may be cryptographically secure, possession of a hashed password provides a quick way to verify guesses for the password by applying the function to each guess, and comparing the result to the verification data.

即使职能创造乱后密码可cryptographically可靠、藏乱后密码提供了一种快速的方式验证密码臆测运用功能每猜想核查结果的比较数据。

Given a robust 52-bit password, you can then use a password manager to take care of the dozens of easily guessable ones used to access various web services.

因有强大的52字节密码，那你需要一个密码经理来照顾数十个登入各式网站但容易被猜到的密码。
