关于前端RSA加密和解密的研究

1.之前项目里与第三方交互需要用到rsa加密，当时研究了一点点，这里做下记录吧，大家觉得有什么问题，勿喷。

2.rsa找的插件，直接贴代码吧

<script type="text/javascript">
var PUBLICK_KEY = 'MIGeMA0GCSqGSIb3DQEBAQUAA4GMADCBiAKBgH9ZK++fC83DV62txcrJ3miwio4y5GlWy0nDrIl7OqshrJC3BVvfesPWijYhCLS53U0RRPc/TCICegWuKTzGWYTRG3o17n7mGd6XE/Lf61a3HPhHL3GaVQgJrXryNedfS+v7vISXEZzhfjNVAPnlJQBERIG7ERxnCX7kxYSXp8cvAgMBAAE=';

function encryptRsa(publickkey,str){

    var encrypt = new JSEncrypt();
    encrypt.setPublicKey(publickkey);
    var encrypted = encrypt.encrypt(str);

    var decrypt = new JSEncrypt();
    decrypt.setPrivateKey(private_key);
    var uncrypted = decrypt.decrypt(encrypted);
    
    console.log("加密结果：" + encrypted);
    console.log("解密结果：" + uncrypted);
    var data = encrypt.debase64(encrypted);
}

3.当时后台没时间联调，只能自己对接口，怎么都不对，后来发现是插件里把结果base64加密了。自己解开就可以了。

4.完整的例子看我的github吧：

5.附带md5的加密方法，还有几种字符转16进制的方法（严格说是字符的Unicode编码转16进制）
