## 说明 此程序可以进行sha1,sha256,md5的加密 在input输入框内输入所需加密的数据,然后点击"encryption"按扭即可实现加密； 默认input输入框内的数据为123456

配合我的blog ： arduino + mysql ， 在线安装的库可能不能直接用，懒得改了，用这个吧

HMAC-SHA1 含密钥的安全哈希算法。为了更安全健壮，采用了密钥的安全哈希算法。

SHA1 数字签名算法实现,将要加密的内存首地址和长度作为参数传入，即可获得对应的20字节的摘要。注释很详细

lua脚本编写的sha1加密

C语言版的实现HMAC-SHA1和base64编码，已经对C++做了兼容处理,在VS下运行main.c代码，可以得到经过HMAC-SHA1处理后的结果，并且可以运行里面的base64编码函数得到想要的结果，可以用于连接阿里云MQTT

对string1进行sha1签名，得到signature

Windows-KB841290-x86-ENU.exe MD5值：58dc4df814685a165f58037499c89e76 --------------------------------------------------------- Version: 1.0 File Name: Windows-KB841290-x86-ENU.exe Date Published: 8/22/2012 File Size: 117 KB ---------------------------------------------------------- Microsoft (R) File Checksum Integrity Verifier V2.05 README file ================================================================ 1.What is File Checksum Integrity Verifier (FCIV)? 2.Features. 3.Syntax. 4.Database storage format. 5.Verification. 6.History. 1.What is fciv? --------------- Fciv is a command line utility that computes and verifies hashes of files. It computes a MD5 or SHA1 cryptographic hash of the content of the file. If the file is modified, the hash is different. With fciv, you can compute hashes of all your sensitive files. When you suspect that your system has been compromised, you can run a verification to determine which files have been modified. You can also schedule verifications regularily. 2.Features: ----------- - Hash algorithm: MD5 , SHA1 or both ( default MD5). - Display to screen or store hash and filename in a xml file. - Can recursively browse a directory ( ex fciv.exe c:\ -r ). - Exception list to specify files or directories that should not be computed. - Database listing. - hashes and signature verifications. - store filename with or without full path. 3.Syntax: --------- Usage: fciv.exe [Commands] Commands: ( Default -add ) -add : Compute hash and send to output (default screen). dir options: -r : recursive. -type : ex: -type *.exe. -exc file: list of directories that should not be computed. -wp : Without full path name. ( Default store full path) -bp : base path. The base path is removed from the path name of each entry -list : List entries in the database. -v

getPackageName.bat 可批量获取apk包名，getSign.bat可获取apk MD5和SHA1，使用简单，readme.txt中已有详细使用使用说明
