Recursive-subroutine

本程序可以在 PE 文件的结尾增加一个新节，从而在已被“加密”的程序开始运行时，要求输入密码。(This procedure can be the end of the document in the PE to add a new section, which has been in the encryption process to start running when asked to enter a password.)

说明：  六种加密算法源码，包括CRC32校验，DES加密，MD5，rsa数字签名，RSA演示，简单加密(Six encryption algorithm source code, including the CRC32 checksum, DES encryption, MD5, rsa digital signature, RSA presentation, simple encryption)

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)

自己写的域天加密狗VB使用小例子，32位的加密狗快速开发源代码(Write your own domain days dongle VB use a small example, 32 dongle rapid development of source code)

RSA数字签名的源代码 vc++6.0实现的版本(RSA Digital Signature vc source code version 6.0)

Base64的编码程序 基于VC++编写的(Base64 encoding program written with VC++)

本文使用ECC加密AES的密钥，再由AES加密明文内容，AES加密强度大，速度快，但是密钥更新繁琐和不安全，由强度很大的非对称密钥算法对AES密钥加密，结合了两方的优点(this programme combine the ECC with AES.using the ECC to cipher the AES key,and using the AES to cipher the m)

基于双缓冲过滤驱动的透明加密系统研究与实现(Based on double buffer transparent encryption system filter driver and Implementation Research)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

对RC4加密解密代码，可以自行修改密钥!类可以直接调用(RC4 encryption and decryption code, you can modify the key! Class can be called directly)
