You can't, you have to create a new certificate.
你不能，你必须创建一个新证书。
The certificate contains a signature of the data it presents (including Owner, Issuer, Fingerpint, ...) and that's what makes up the certificate in the first place.
证书包含它所呈现的数据的签名（包括所有者、发行者、Fingerpint 等），这首先构成了证书。
Put differently: A certificate is designed specificallyso that this data can't be modified after its creation.
换句话说：证书是专门设计的，因此在创建后无法修改此数据。

Using BurpSuite, you can modify the certificates Issuer Name. Step 1: Copy paste the certificate data from Begin Certificate to End certificate Step 2: Decode the certificate information Step 3: Use the ASN.1 format to get details on Certificate information Step 4: Modify the information and encode it back to B-64 format.
使用 BurpSuite，您可以修改证书颁发者名称。步骤 1：将证书数据从开始证书复制粘贴到结束证书步骤 2：解码证书信息步骤 3：使用 ASN.1 格式获取证书信息的详细信息步骤 4：修改信息并将其编码回 B-64格式。
But anyways the loading to the library will fail .
但无论如何加载到库将失败。
