鉴于单纯设置一个计数器易被查出，通过修改使其不起作用。我们设计的程序可以通过数据文件，软件执行前通过关键字找到计数基数，然后计算和判别，如果在合理范围，则设定新的关键字，将计数基数放在新关键字指定的位置，并执行子程序 则启动自毁程序。

详细介绍了C函数。

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
