How to retrieve the delta cdp and revocation reason?

[surendra.ande]

Hi Team,

 

I am working on the CRL validation. I am seeing some issues in extracting the

- delta crl distribution point and

- reason for revocation.

 

Could you please let me know your thoughts on how to access these two above mentioned information?

 

Let me explain you my problem clearly:

1. I got the crl from X509_STORE *ctx.

2. After receiving the crl, I checked the certificate, wheather is revoked.

3. I found that, the certificate is revoked(serial number is present)

4. After that, I would like to find the certificate revocation reason. But I am not able to extract the information.

5. Since the delta crl is enabled, I need to get the cdp (crl distribution point) for delta crl. I am not able to retrieve the information.

 

Could any body help me in retrieving the

- Delta CRL distribution point and  

- CRL reason for revocation

 

I am using the following data structues for CRL.

 

struct X509_crl_st
 {
 /* actual signature */
 X509_CRL_INFO *crl;
 X509_ALGOR *sig_alg;
 ASN1_BIT_STRING *signature;
 int references;
 } X509_CRL ;

 

typedef struct X509_crl_info_st
 {
 ASN1_INTEGER *version;
 X509_ALGOR *sig_alg;
 X509_NAME *issuer;
 ASN1_TIME *lastUpdate;
 ASN1_TIME *nextUpdate;
 STACK_OF(X509_REVOKED) *revoked; //It should give the revocation reason.
 STACK_OF(X509_EXTENSION) /* [0] */ *extensions; //It should give the cdp for delta crl.
 ASN1_ENCODING enc;
 } X509_CRL_INFO;

 

 

Appreciate your help on the same.

 

With best regards,
