Hey Stefan,
Have you decided what you're going to do about GOST? I'm asking
because if you disabled it in the OpenSSL build, I'd be able to test
it in a nightly build, perhaps before you roll 1.7.2. I also wanted
to make sure that you understand you can disable just the GOST engine
in OpenSSL while still leaving all the CAPI features enabled.
Unfortunately, I don't have any way of knowing if any TSVN users use
the GOST cypher or not. I doubt it, but I won't be getting the angry
emails if I'm wrong! Thanks for all your help working through this
issue.
