Title: RE: Is OpenSSL 0.9.7-beta3 compatible with 0.9.6.2?

Hi Stephen,

For my OCSP implementation, I've taken the new OCSP components from 0.9.7-beta3 and have integrated it with 0.9.6.2. Have not tested it but I anticipate number of problems due to incorrect ASN encoding/decoding, mainly due to some of the attributes being EXPLICIT, IMPLICIT, OPTIONAL and CHOICE etc.

Porting macros like ASN_SEQUENCE etc in 0.9.6.2 also doesn't seem to be easy. Can you suggest me some reading material or some guidelines for correct ASN encoding/decoding in 0.9.6.2 release?

Regards,
-Mayank.

The new OCSP code in 0.9.7 makes use of the rewritten ASN1 library, which
isn't in 0.9.6 so this would be a lot of effort.
