What about them? Would you recommend one of them over the others?
Even if they have bugs (it is unlikely they don't), they'll still have less bugs than own implementation.
If you are still not convinced, at least give user option what to use.
curl[1] is a good example of giving freedom to the user.
Are you aware that we did not roll our own crypto? Instead we used the NaCl crypto libs[1]. Weave adds about 300 LOC to integrate NaCl.
You can read about it here - http://docs.weave.works/weave/latest_release/how-it-works.ht... You can also read a bit about weave crypto in the comments from mradestock and msackman elsewhere on this page.
I would be extremely grateful if you could provide actionable advice (or help) on which other crypto libraries could fit our requirements for weave. Please note that in addition to functional requirements, any library must be open source, hard to misuse, easy to package, and demonstrably safe.
