RSA implementation by using Java

数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.

rsa加密算法的vc实现，可以实现1024位的加密-the source code of rsa algorithm in vc,which can do 1024bits encryption.

md5算法的java源代码-md5 algorithm source code of java

VC实现的图像加密算法，采用Arnold变换，对于初涉信息安全的人员有一定参考价值-The algorithm of encrypted image completed in VC, applying the Arnold transform .It is valuable to people who will devote himself to infomation security

随着二维码的不断发展，生活中有越来越多的二维码识别程序，本程序识别典型的二维码，为本人课程设计时写的代码，在识别时仅识别典型的二维码。

c++的基于openssl实现的简单aes文件加密类 -c++ realize openssl based on a simple type of file encryption aes

用c＋＋(Crypto++)实现的，基于ecc的序列号生成代码，包含测试数据，和ECDSA文档-Using c (Crypto++) Realize, based on the serial number of ecc generated code, including test data, and documents ECDSA

几个密码算法的源代码，不知道有了没有~~ 下的人多了就继续上传-Some source programs of encryption arithmetic.I don t know whether it is always existed or not.I will upload it if a lot of people have downloaded.
