SQLCipher的版本和SQLite的版本不是一回事，看清楚了再下载，避免浪费积分！！！SQLCipher2.2.1自己根据2.2.1的源码编译的(网上用过其它编译好的，但功能不全)，用于Windows环境解密数据库，直接还原SQLite库，取消密码。
不适用于3.X版本。

SM4国密加密算法C语言实现包括Spec，C代码，测试用例和分组密码有五种工作体制：1.电码本模式（ElectronicCodebookBook(ECB)）；
2.密码分组链接模式（CipherBlockChaining(CBC)）；
3.计算器模式（Counter(CTR)）；
4.密码反馈模式（CipherFeedBack(CFB)）；
5.输出反馈模式（OutputFeedBack(OFB)）

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
