md5算法的java实现-md5 algorithm java realizes

Microsoft CryptoAPI中公私密钥对的使用、HASH算法、数字签名等技术-Microsoft CryptoAPI in the use of public-private key pair, HASH algorithm, digital signature technology

java编写MD5加密生成例子，对于需要加入密码验证的程序绝对实用，可以进行直接拷贝使用。-prepared MD5 encryption generated example, the need for password verification procedures for the practical, direct copy.

这个小软件通过在可执行文件(.exe)的尾部添加一个新节(Section)，并且修改PE的入口地址，使可执行文件在运行时，跳出一个输入密码的对话框，从而实现了简单的加密。-small software in executable files (. Exe) to the tail adding a new section (Section), and amend the PE import addresses, so that the executable file is run, jump out of a password dialog box, thus achieving a simple encryption.

详细的介绍了RSA的实现过程，以及它的优化-Detail the realization of the RSA process, as well as its optimization

md5单向散列加密算法,此压缩包,包含完整调用DLL源码,PB格式.导入后直接可以应用.-md5 hash encryption algorithm, this compressed, includes a complete calling DLL source, PB format. After the direct import can apply.

这是密码学的一个常用算法rifndael算法，unix环境下的，对于学习密码学很有帮助啊。-This is a cryptographic algorithm used rifndael algorithm, unix environment. learning cryptography helpful ah.

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)

VC实现RSA算法的程序，好东西啊，vc6.0编译通过-VC to achieve RSA algorithm procedure, a good thing ah

目前企业面临的计算环境和过去有很大的变化，许多数据资源能够依靠网络来远程存取，而且越来越多的通讯依赖于公共网络公共网络（如 Internet），而这些环境并不保证实体间的安全通信，数据在传输过程可能被其它人读取或篡改。-currently facing the enterprise computing environment and past a great change, many data resources to be able to rely on remote network access, and more and more dependent on public communications networks public networks (such as the Internet), which environment is not a guarantee of the security entities communications, data transmission possible by other people read or tampered with.
