Encryption methods include: 1. Use the "window.btoa(value)" statement to encrypt; 2. Use hex_md5(), b64_md5(), str_md5() and other functions to encrypt; 3. Use sha1() function to encrypt; 4. Use the escape() function to encrypt; 5. Use AES to encrypt.
The operating environment of this tutorial: windows7 system, javascript version 1.8.5, Dell G3 computer.
Example
<html> <head> <title>前端的base64使用方法</title> </head> <body> </body> <script> var str = "hello"; var str64 = window.btoa("hello"); console.log("字符串是:"+str); console.log("经base64编码后:"+str64); console.log("base64解码后:"+window.atob(str64)); </script> </html>
About MD5:
MD5.js is a tool that encrypts user information, passwords and other private information through front-end js encryption. It can also be called a plug-in.
MD5 has 6 encryption methods:
1, hex_md5(value)
2, b64_md5(value)
3, str_md5(value)
4 , hex_hmac_md5(key, data)
5, b64_hmac_md5(key, data)
6, str_hmac_md5(key, data)

After downloading, use the script tag to import and use
<script src="md5/md5.js"></script>"></script> <script> var code = "123456"; var username = "123456"; var password = "123456"; var str1 = hex_md5("123456"); var str2 = b64_md5("123456"); var str3 = str_md5("123456"); var str4 = hex_hmac_md5(code,code); var str5 = b64_hmac_md5(username,username); var str6 = str_hmac_md5(password,password); console.log(str1); // e10adc3949ba59abbe56e057f20f883e console.log(str2); // 4QrcOUm6Wau+VuBX8g+IPg console.log(str3); // áÜ9IºY«¾VàWò��> console.log(str4); // 30ce71a73bdd908c3955a90e8f7429ef console.log(str5); // MM5xpzvdkIw5VakOj3Qp7w console.log(str6); // 0Îq§;Ý��9U©��t)ï </script>
The sha1.js download address is not found here, so find the online file in bootcdn and import it. , you can download it from bootcdn if you need it
<script src="https://cdn.bootcss.com/js-sha1/0.6.0/sha1.js"></script> <script type="text/javascript"> var sha1_1 = sha1("mosquito~"); console.log(sha1_1); var sha1_2 = sha1("admin:1001"); console.log(sha1_2); </script>
Use the JS function escape() and unescape() to encode and decode strings respectively
<script type="text/javascript"> var escape1 =escape("我的名字是:mosquito~");//编码 console.log(escape1); var unescape1 = unescape(escape1); //解码 console.log(unescape1); </script>
Download crypto-js.js The introduction URL is click to download
var aseKey = "12345678" //秘钥必须为:8/16/32位 var message = "80018000142"; //加密 var encrypt = CryptoJS.AES.encrypt(message, CryptoJS.enc.Utf8.parse(aseKey), { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }).toString(); console.log(encrypt); //VKrZlqykem73x8/T2oCfCQ== //解密 var decrypt = CryptoJS.AES.decrypt(encrypt, CryptoJS.enc.Utf8.parse(aseKey), { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }).toString(CryptoJS.enc.Utf8); console.log(decrypt); //80018000142
[Note]: It must be converted into a string when encrypted. toString. When decrypting, the format of utf8 must be used
