这是反汇编驱动程序的源代码这是反汇编程序的源代码-This is the anti-driven compilation of a program"s source code that is anti-assembler source code

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

ECC加密算法入门介绍-ECC encryption algorithm introduced entry

这是一个古典加密算法。是最近自己编写的。-This is a classical encryption algorithm. Recently prepared themselves.

uthash 是一个C语言的哈希表，支持各种结构类型的存储、添加、删除，这些操作都在固定的时间完成，跟哈希表本身的大小无关。键也可以是任何类型的数据。-is a C language uthash the hash table to support a variety of structural types of storage, add, delete, these operators are in a fixed time to complete, with the hash table size in itself has nothing to do. Keys can also be any type of data.

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler
