@delta “six security audits overall” but the one you link to says “Yet, the security of its protocols has not been studied to date.”. Claiming you had 6 security audits in total, when 5 of them apparently didn’t look at your protocol, in a conversation about the security of the protocol, is misleading at best.

@mxey good question. Research studies are actually a different thing than security audits. So more precisely we would need to say "five security audits and one research study" and the research study is referring to the relative lack of research studies, not security audits (we don't know of any messenger that has more published security audits than ours btw).

@delta
Wire lists a lot of audits, but has not published them AFAIK:
wire.com/en/security

WhatsApp might actually have a lot of published audits, e.g. nccgroup.com/us/research-blog/, but you need to search for them.
