我现在用的是Crypto插件的AES/CFB/NoPadding，项目要求是要把6个单字节的16进制字节集作为明文，然后16个单字节的16进制字节集作为key，16个单字节的16进制字符集作为iv

但是，，，，，，测试了好久发现都是加密结果对不上，解密结果却是正确的！！

附上代码：

var text = crypto.Utf8.parse(String.fromCharCode(0x11, 0x22, 0x33, 0x44, 0x55, 0x66));

console.log('----------------------------------------------------------明文：', text);

var keys = hexMD5(String.fromCharCode(0xBC, 0x9A, 0x78, 0x56, 0x34, 0x12));

var XMD5Keys = crypto.Utf8.parse(String.fromCharCode(this.DEE(keys)));

console.log('----------------------------------------------------------密钥：', XMD5Keys);

var iv = hexMD5(String.fromCharCode(0x01,0x23,0x45,0x67,0x89,0xab,0xcd,0xef,0xef,0xcd,0xab,0x89,0x67,0x45,0x23,0x01));

var EMD5iv = crypto.Utf8.parse(String.fromCharCode(this.DEE(iv)));

console.log('----------------------------------------------------------向量：', EMD5iv);

var mi = new crypto.AES().encrypt(text, XMD5Keys, {iv: EMD5iv,mode: crypto.Mode.CFB,padding: crypto.Padding.NoPadding});

console.log('----------------------------------------------------------加密:', this.DEE(mi.ciphertext.toString()));

var v = new crypto.AES().decrypt(mi.toString(), XMD5Keys, {iv: EMD5iv,mode: crypto.Mode.CFB, padding: crypto.Padding.NoPadding});

console.log('----------------------------------------------------------解密:', this.DEE(v.toString()));
