还记得上周使用百度翻译API的时候，需要提交以下字段。

那么，我在Vue.js中得如何将sign加密成MD5呢？

(百度很多方法，都是让我们装插件，可是我赛扬处理器带不动那么多插件呀！！！)

不装插件那就只能自己写代码啦！

代码有点长，最底部也提供了DEMO的下载地址，可以自行下载！

使用方法：
hex_md5(“我想把整个八本那年加密了”)
将需要加密的内容传递进这个方法，返回值即加密后的MD5

hex_md5(a) {
    if (a == "") return a;
    return this.rstr2hex(this.rstr_md5(this.str2rstr_utf8(a)))
},
hex_hmac_md5(a, b) {
    return this.rstr2hex(this.rstr_hmac_md5(this.str2rstr_utf8(a), this.str2rstr_utf8(b)))
},
md5_vm_test() {
    return this.hex_md5("abc").toLowerCase() == "900150983cd24fb0d6963f7d28e17f72"
},
rstr_md5(a) {
    return this.binl2rstr(this.binl_md5(this.rstr2binl(a), a.length * 8))
},
rstr_hmac_md5(c, f) {
    var e = this.rstr2binl(c);
    if (e.length > 16) {
        e = this.binl_md5(e, c.length * 8)
    }
    var a = Array(16),
    d = Array(16);
    for (var b = 0; b < 16; b++) {
        a[b] = e[b] ^ 909522486;
        d[b] = e[b] ^ 1549556828
    }
    var g = this.binl_md5(a.concat(this.rstr2binl(f)), 512 + f.length * 8);
