Description battery.staple 2015-08-30 16:33:02 UTC
The current upstream source used (2.7d) only uses up to 1024 bit Diffie-Helman keys. I don't believe this is considered strong any more. The final release of 2.7 supports 2048 bit - I believe it's the default. Can the upstream source code in this package be updated from the pre-release version (2.7d) to the final release of 2.7?

Comment 1 neil 2015-08-31 21:52:21 UTC
It would be great to see a version bump on this, 2.7 final also adds ECDHE class cipher support (which 2.7d does not have).

With no ECDHE ciphers and only DHE (with weak parameters) ciphers available in 2.7d, the remaining list of viable ciphers is very short, none of which feature forward secrecy.
