微信小程序aes-128 ECB加密和解密
在最近做的微信小程序中，客户使用了aes-128加密的传输的蓝牙连接，查询了许多资料终于做出来了。
下面是源码:
加密：
// 加密 aesEncrypt1: function (code) { //key和code需要使用十进制的数组表示 var a = this; var o = [58, 96, 67, 42, 92, 1, 33, 31, 41, 30, 15, 78, 12, 19, 40, 37]; //key的密钥10进制 var t = fun_aes.CryptoJS.enc.int8array.parse(o); var r = fun_aes.CryptoJS.enc.int8array.parse(code); var n = (r.toString(fun_aes.CryptoJS.enc.Base64), fun_aes.CryptoJS.AES.encrypt(r, t, { iv: [], mode: fun_aes.CryptoJS.mode.ECB, padding: fun_aes.CryptoJS.pad.NoPadding })); var w = fun_aes.CryptoJS.enc.int8array.stringify(n.ciphertext); return w; },
解密：
//解密 aesDecrypt: function (code) { // l = [186, 19, 158, 249, 192, 228, 128, 165, 171, 212, 226, 171, 211, 219, 145, 71], var a = this, l = code, o = [58, 96, 67, 42, 92, 1, 33, 31, 41, 30, 15, 78, 12, 19, 40, 37], t = fun_aes.CryptoJS.enc.int8array.parse(o), r = fun_aes.CryptoJS.enc.int8array.parse(l).toString(fun_aes.CryptoJS.enc.Base64), n = fun_aes.CryptoJS.AES.decrypt(r, t, { iv: [], mode: fun_aes.CryptoJS.mode.ECB, padding: fun_aes.CryptoJS.pad.NoPadding }); n = fun_aes.CryptoJS.enc.int8array.stringify(n); return n; },
