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)
