⽤法：
com.str.Encrypt("2017-05")//结果：68f4a7903a9fe6085d2301ac68cc039c
com.str.Decrypt("68f4a7903a9fe6085d2301ac68cc039c")//结果：2017-05
//加密
string str1 = Encrypt.EncryptByAES("2017-05", "12345678900000001234567890000000");
//解密
string str2 = Encrypt.DecryptByAES("68f4a7903a9fe6085d2301ac68cc039c", "12345678900000001234567890000000")；注：前后台的加密Key必须⼀致。
