支持php、c#、java、javascript、golang、swift、flutter-drat的通用aes-cbc-127 pkcs7填充算法例子
详细请查看https://mikudoc.com/balrogsxt/apidemo 加密解密篇，内有调试截图等信息
这里只显示4种算法，详细请查看链接后续会增加更多通用算法
php加密
//密钥偏移均为16位字符串 $key = '密钥'; $iv = '偏移'; $data = "加密数据内容"; $result = openssl_encrypt($data,'aes-128-cbc',$key,0,$iv) //$result即为加密返回数据字符串
php解密
//密钥偏移均为16位字符串 $key = '密钥'; $iv = '偏移'; $data = "解密数据内容"; $result = openssl_decrypt($data,'aes-128-cbc',$key,0,$iv); //$result即为解密返回数据字符串
Js加密
let c = require("crypto-js");//导入crypto-js
//密钥偏移均为16位字符串
let key = '密钥';
let iv = '偏移';
let data = '加密内容';
data = c.enc.Utf8.parse(data);
key = c.enc.Utf8.parse(key);
iv = c.enc.Utf8.parse(iv);
let r = c.AES.encrypt(data, key, {
iv,
mode: c.mode.CBC,
padding: c.pad.Pkcs7
});
let result = r.toString();
//result及为加密结果Js解密
let c = require("crypto-js");//导入crypto-js
//密钥偏移均为16位字符串
let key = '密钥';
let iv = '偏移';
