VB程序注册机范例，控件简单实用，采用流行且难以破解的算法加密机器码、序列号、注册码，能更好地保护您的软件(VB program RI example, the controls simple and practical, using the popular and difficult to machine code to crack the encryption algorithms, serial numbers, registration codes, can better protect your software)

加密程序的，实现了对代码的抽取乱序,区段加密和IAT的处理。 (Encryption procedures, the code of the extraction sequence, block encryption and IAT processing.)

说明：  一个关于加密音频，图像的VB程序，功能还算可以，希望可以帮到人！！(One on encryption of audio, images VB program, function OK, the desire to help people! !)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

100 多个加密和解密可以用到的库, 本人悉心收藏的精品(100 can be used to encrypt and decrypt the library, my collection of boutique carefully)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

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. )

用于车型定位识别所用的加密狗文件，非常实用(Dongle for vehicle location identification file used, very practical)

使用DES算法；可以指定使用DES、2DES或者3DES算法；可以对任意的文件进行加密和解密，加密后文件扩展名为.des，可以指定使用ECB,CBC,CFB,OFB,CTR的任意一种模式； (The use of DES algorithm can specify the use of DES, 2DES or 3DES algorithm can arbitrary file encryption and decryption, encryption, named after the file extension. Des, you can specify the use of ECB, CBC, CFB, OFB, CTR arbitrary a model )
