Security Audit #159

Closed sosaucily closed 11 months ago

sosaucily commented 11 months ago

Hi team, thanks for your hard work on this library, and so many others.

I'm interested in using the SRP package, and am wondering if you believe it to be production-ready, and what the process would be for getting a third-party audit firm to review it. I have some connections to various well-known firms, but I wonder if you have some in particular that you require.

Thanks!

srp needs a bit of work, it would be nice to migrate it to crypto-bigint and we have two pending PRs for it. You probably could use the current version in production, but I am not sure if the current impl is constant time.

@sosaucily we're not too picky about free audits. Some of the others have been by NCC Group and Cure53, though at least the former is somewhat notoriously backlogged

Thanks @newpavlov @tarcieri for the repsonses - I'm not too worried about constant time, as long as the worst case isn't a terrible user experience. I guess it wouldn't be noticeable during a user login flow for a standard app.

Great, thanks for the feedback. If we decide to use SRP, it will be this repo, and I'll re-engage the idea of a security audit.
