There was a problem hiding this comment.
given the experimental project status, maybe it makes since to move this into modern ssl and move the current modern ssl to legacy (but this would remove support for the existing legacy client)

Thanks for working on this! The PR compiles, but the sample does not run. Something is off in the BIO/socket handling. Trying to run the sample, with network code enabled, returns: originating from the call to I was looking at how This is a bit deeper into OpenSSL APIs than I am familiar with, so I can't really work it out beyond this. |
