des文件加密系统。

快速MD5碰撞生成器，王小云改进版。这个生成器根据“构造前缀碰撞法”可以生成两个不同的文件，而这两文件的md5 sum却是一样的。 MD5 Collision Generator(win32 .exe) MD5 Collision Generator(source) -Fast MD5 collision generator, Xiaoyun Wang, improved version. The generator according to "construct the prefix collision" system can generate two different files, while the md5 sum of these two documents is the same.

简单的基于DES的加密算法及雪崩效应分析。请仔细阅读内附的说明文件。-DES encryption algorithm and analysis of avalanche effect. Please read the attached note.

有多种加密算法，如：字节取反、循环异或、码变换法、CSED、D3DES。-There are a variety of encryption algorithms, such as: anti-byte check, recycling XOR, code transformation, CSED, D3DES.

此代码提供关键时间表中的数据加密标准 (DES)，这是生成子密钥的算法的实现的。 • 输入： （长度 （64 位） 的任何字符串。 • 输出： 16 子键产生的 DES （每个 48 位长度）。 如何使用它： 1.>> K = DES_KeyScheduling %会创建一个类 "DES_KeyScheduling" 的对象。 2.>> K.KEY_STRING = "密码" %设置的加密密钥值。 3.>> K.printPC2() %打印输出的置换选择 2 （PC-2） （也称为 x 16 48 及其子键） 无压痕。用来调用函数 1 "K.printPC2(1)" 要输出带缩进值。

PGP Software Development Kit Cryptographic Module  Operational Test Notes WHAT IS IT? ---------- The optest program is used as part of the FIPS 140-2 validation process. In particular, section  TE03.14.02  which requires that the tester shall perform each of the specified services and observe that that they have been implemented  properly.   As a side benefit to clients of the  SDK this code can also be used a good example of how to perform a number of commonly used functions, whether or not the developer intends to run in FIPS mode.   Depending on what option is chosen from the command line the following tests will be run: FIPS MODE SPECIFIC TESTS ------------------ - Invoke the Approved mode of operation (optest.c)     This involves Initializing the SDK, checking
