老外写的加密库cryptlib(版本3.1)

DES算法实现，非常有用，对于研究加密的朋友希望回有帮助-DES algorithm, very useful for research encryption friends want to return to help

按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model

关于IDEA算法的一个小程序-IDEA algorithm on a small program

一些重要的加密算法的实现---主要是针对大学密码学课程中的算法实践，例如： 维吉尼亚密码，置换密码，移位密码-Some key encryption algorithm--- mainly aimed at the realization of the University of cryptography algorithms for practical courses, such as: Virginia password, replacement password, password, and so shift

这是jacobi迭代算法-iterative algorithm to caculate Jacobi(matrix?)

c++写的md5加密算法，易于移植 md5加密-c++ to write the md5 encryption algorithm, easy to transplant md5 encryption

硬盘保护锁,绝对经典，研究硬盘加密的不得不看呀-Hard drive protection locks, an absolute classic, researchers have looked hard disk encryption

java加密程序-java encryption

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in

access数据库加密有几法，但用“设置安全机智向导”加密最为牢靠，又如何访问这样的数据库呢-access database encryption with a few laws, but "to provide a safety witty guide" the most secure encryption, how to access such a database?
