# 网络子系统Changelog

## certVerification接口和certVerificationSync接口错误码2305001细化

**访问级别**

公开接口

**变更原因**

对2305001 - Unspecified error错误进行细化调整。

**变更影响**

该变更为不兼容变更。

变更前：输入上下文非法的证书及自验证证书返回错误码：2305001，错误信息：Unspecified error。

变更后：输入上下文非法的证书返回错误码：2305069，错误信息：Invalid certificate verification context；输入自验证证书返回错误码：2305018，错误信息：Self-signed certificate。

**起始API Level**

API 11

**变更发生版本**

从OpenHarmony SDK 5.0.0.38开始。

**适配指导**
以下两个用例分别为错误码2305069和2305018的测试用例，测试时请将Verifying the 2305069 Error Code of the CertVerification用例中的'your Self-signed certificate data'替换为开发者真实使用的自签名证书内容。
