How to decode ASN1 blob using Windows wincrypt api?

Asked by At

I'm trying to extract attributes from a certificate on Windows and have been using Wincrypt api's for that.

When I encouter the SUBJECT_ALT_NAME certificate extension (szOID_SUBJECT_ALT_NAME "") with the "OTHER_NAME" option - I get the CERT_OTHER_NAME struct which I cant find the correct API to decode it a char string.


I can see the value in it's CRYPT_OBJID_BLOB member is ASN1 decoded (UTF8 string) however CertNameToStrW fails to decode it when passing as the blob.

Any appropriate way to decode this structure (without manually decoding it)
