MD5

SHA1安全哈希算法（Secure Hash Algorithm）主要适用于数字签名标准 （Digital Signature Standard DSS）里面定义的数字签名算法（Digital Signature Algorithm DSA）(SHA1 Secure Hash Algorithms are mainly applicable to Digital Signature Algorithms (DSA) defined in Digital Signature Standard DSS.)

PF140.514版digsilent软件的两个破解文件，按一定操作步骤即可免狗驱动，本人已在XP环境下使用，没有问题。希望对采用该软件的人有一点帮助！(Two crack file PF140.514 the version digsilent software, Free Dog certain steps to drive, I have XP environment, there is no problem. I hope the software a little help!)

SM2 签名 验签 C 语言实现来做到签名 验证签名 非常好的资源(SM2 signature verification C language implements very good resources for signing signature verification signatures)

加密解密(Encoder)C#源代码 v1.0 加密解密(Encoder)，实现MD5加密，DES加密解密，RSA加密解密。使用的是System.Security.Cryptography 命名空间提供的相关类(Encryption and decryption (Encoder) C# source code v1.0 Encryption and decryption (Encoder), achieve MD5 encryption, DES encryption and decryption, RSA encryption and decryption. Using System.Security.Cryptography namespace provides related classes)

这是一个小程序,凯撒解密,自己写的,以后还会扩展的(This is a simple program for a example of ceasar cipher. It is produced by myself and I want to extend it to a substitution cipher program in some days.)

基于RSA算法的加密解密以及数字签名系统，实现加密解密签名的功能(RSA-based encryption and decryption algorithms and digital signature system to achieve the function of signature encryption and decryption )

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))

ElGamal加密算法，经过测试可以编译运行(ElGamal Encryption )

说明：  idea算法VC++源码，包含系列文件 idea.h idea.cpp ideadlg.h ideadlg.cpp resource.h stdafx.h stdafx.c(idea algorithm VC++ source, including the series of documents idea.hidea.cppideadlg.hideadlg.cppresource.hstdafx.hstdafx.c)

SPN密码实现和分析（也就是破解），通过文件读入！(SPN password implementation and analysis (ie cracked), read through the file!)
