Let’s say, I create a bank with the caveat that all of my banking phone apps and webapps are FOSS (or if they depend on non-free components — banks probably do to communicate with each other —, then just OSS). Am I going to be behind the competition by doing this?
If the most secure crypto algorithms are the ones that are public, can we ensure the security of a bank’s apps by publicizing it?
Are they not doing this because they secretly collect a lot of data (on top of your payment history because of the centralized nature of card payments) through these apps?
EDIT: Clarifying question: Is there a technical reason they don’t publicize their code or is it just purely corporate greed and nothing else?
I’m well aware that Cloudflare holds the TLS keys. I’m also well aware that that does not equal having access to credentials.
Banks certainly can not outsource willy nilly. Or well, I suppose they may in some jurisdictions, but the context here is Europe, where the banks actually are regulated.
Can you elaborate? I believe the hashing must be done on the server side not the user side, so Cloudflare would see the creds before hashing. I know it’s possible to subscribe to an enterprise package where you hold your own SSL keys, but it’s unclear why CF would even be used in that scenario. If CF cannot see the traffic, it cannot optimize it as it all has to be passed through to the original host anyway. AFAICT, CF’s only usefulness in that scenario is privacy of the websites ownership - something that banks would not benefit from.
US banks (esp. credit unions) outsource with reckless disregard for just about everything. Europe is indeed different in this regard. But European banks have no hesitation to outsource email to Microsoft or Google and then to use email for unencrypted correspondence with customers. That crosses a line for me.
European banks will also outsource investments to JP Morgan (one of the most unethical banks in the world), and they tend to be quiet about it. I boycott JPM along with other similar banks in part due to investments in fossil fuels and private prisons. This means banking in Europe is a minefield if you boycott the upstream baddies.
