question about certificate verify

["forston_shi@xxxxxxxxxxxxxx" <forston_shi@xxxxxxxxxxxxxx>]

Hi Openssl team,

I have a question about certificate verify.

 

We check a sub-certificate with a lot of root certificates.

We don’t want to check sub-certificate’s expire time, but we want to get an error when root certificate expired.

 

I try to verify it by following option,

  X509_VERIFY_PARAM* pm = X509_STORE_CTX_get0_param(xstore_ctx);

  X509_VERIFY_PARAM_set_flags(pm, X509_V_FLAG_NO_CHECK_TIME);

 

  iret = X509_verify_cert(xstore_ctx); 

 

But it also will ignore root certificate’s expire.

 

So, can you give me some suggestion for my question.

 

Best regards

Forston Shi (RD-CN)
