Lock Manage 是一个功能比较全面的加密软件。 它具有多种加密方案：如文件口令加密，文件反拷贝加密，软硬盘加密，安装加密，文本加密，批处理加密等等。系统是由Ｃ和汇编写成，可从外部链接于主模块。可单独编译，单独调试。可执行ＥＸＥ／ＣＯＭ程序加密模块已经过长时间的测试分析，其工作性能己十分稳定。可移植性与兼容性很好。另外，代码实现了ＣＳ，ＤＳ不换技术，使其ＳＨＥＬＬ性能难以被ＤＥＢＵＧ识别。其内部密码采用单向不可逆变换，基本实现了不可解，原因在于四个随机密钥只能用穷举法找出。这种可靠原四密钥单向加密技术渗透到了后面的几个程序中。对于反拷贝加密，采用了随机的软指纹生成技术，可生成唯一密钥母盘。硬盘反拷贝在硬盘里产生四密钥，在非母机上程序运行错误。反反汇编可将整个文件的内容加密变换。反跟踪采用了目前十余种通用的反跟踪算法。可抵抗ＤＥＢＵＧ系列软件。批处理和文本加密十分方便，但保密性不太强，只能用于一般用户。-Lock function is a more comprehensive encryption software. It has a wide variety of encryption programs : documents such as password encryption, anti-copy document encryption, hard disk encryption software, the installation of encryption, encrypted text, etc. batch encryption. C system is written and compiled, from the external links in the main module. Separately compiler, debugger alone. EXE executable/COM procedures encryption module has been tested over a long period of analysis, their performance has very stable. Good portability and compatibility. In addition, the implementatio
