首先需要注意的一点是，密码的加密应该是在页面完成的，因为传输的过程中，密码明文有可能会泄露出去。然后要说明的就是，虽然在页面加密密码，加密算法暴露了，但是有些加密算法，比如MD5,即使知道加密算法，知道密文也很难得出明文是什么。MD5是使用散列函数进行密码加密的，加密是单向的，如果不是两段相同的明文，结果很难一致。网上有MD5的解密工具，但是那种工具一般都是查字典出来的，也就是说那种工具会在后台进行查找，如果它的数据库里没有明文，它是解密不了密文的。Crypto:https://code.google.com/archive/p/crypto-js/downloadsCrypto's api:https://code.google.com/archive/p/crypto-js/Instance code:html> head> meta charset="UTF-8"/> title>title> script src="./md5.js">script> script > function escape(){var c
