有关欧几里德的扩展算法，非常实用，经测试好用

Serpent算法,想必搞相关行业的朋友看到压缩文件名字就知道是什么了！-Serpent algorithm, must engage the relevant industry friends to see compressed file name know what it is!

安全加密算法sha-1，又方便的调用接口，可用于普通文件的加密-security encryption algorithm sha-1, convenient call interface can be used for document encryption

汇编内核的MD5算法C源码,核心运算部分采用汇编语言编写，执行高效。VC++环境开发，由于直接在C代码中直接嵌入汇编，因此可无须另外设置，可直接使用。

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.

IBE基于身份的加密系统的身份提取程序，使用VC6.0开发，即把身份转换成椭圆曲线上的点-IBE identity-based encryption system of the identity of extraction procedures, using VC6.0 development, namely, the identity into a point on the elliptic curve

aes加密与des加密（包括三重des加密与cbc工作模式）-aes encryption and des encryption (including triple-des encryption and cbc mode)

是大方的师傅是大方的师傅说的是大方的师傅的师傅说的-的师傅的师傅是大方的师傅都是

base64编码-base64 encoding

PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.

使用自定义密码 进行文件加密 使用传入密码生成 SymmetricAlgorithm-You can encrypt and decrypt file with your password.
