can anyone tell me for sure if OCSP multi stapling is supported by/implemented in the current version of OpenSSL?
Those are the hints I found on the Web:
OCSP stapling now is supported by OpenSSL, see also a security note from 22 September 2016: https://www.openssl.org/news/secadv/20160922.txt
Mailing list entry from February 2016 discussing it: https://mta.openssl.org/pipermail/openssl-dev/2016-February/005309.html
When looking on the GitHub project, you see a "status_request_v2" entry (the TLS handshake extension for OCSP multi-stapling): github.com/openssl/openssl/blob/master/crypto/x509v3/v3_tlsf.c#L50
Does anyone have more insight into the current version of OpenSSL regarding OCSP multi-stapling?
