Swift AES128加密解密

使用第三方框架：

pod 'CryptoSwift'  #AES加密解密
 
需要的时候调用以下两个方法
    // AES加密
    classfuncaes_encrypt(_ str:String, aes_key:String) -> String{
        var encryptedStr = ""
        do {//  AES encrypt
            let encrypted = tryAES(key: Array(aes_key.utf8), blockMode: ECB(), padding: .pkcs7).encrypt(str.bytes);
            let data = Data(base64Encoded: Data(encrypted), options: .ignoreUnknownCharacters)
            //加密结果从data转成string 转换失败  返回""
            encryptedStr = String(bytes: data!.bytes, encoding: .utf8) ?? ""
        } catch {
            print(error.localizedDescription)
        }
        return encryptedStr
    }

    //  AES解密
    classfuncaes_decrypt(_ str:String , aes_key:String) -> String{
        //decode base64
        let data = Data(base64Encoded: str, options: .ignoreUnknownCharacters)!
        var decrypted: [UInt8] = []
        do {
            // decode AES
            decrypted = tryAES(key: Array(aes_key.utf8), blockMode: ECB(), padding: .pkcs7).decrypt(data.bytes);
        } catch {
            print(error.localizedDescription)
        }
        //解密结果从data转成string 转换失败  返回""
        returnString(bytes: Data(decrypted).bytes, encoding: .utf8) ?? ""
    }
 
比如：
                       let  decrptDataStr = self.aes_decrypt(dict["data"] as? String ?? "", aes_key: "解密密钥")
                        print("解密结果=" + decrptDataStr)
