利用替换算法的加密算法!

参考了电脑爱好者2000第10期的一篇关于将文件隐藏于位图中的文章，本程序还有许多可以改进的地方，例如可以加入CRC校验，加密,多线程等内容。-reference to the 2000 resolution computer enthusiasts 10 of a document on Bitmap hidden in the article, there are many procedures can be improved, for example, can join the CRC, encryption, such as multithreading.

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
