It's possible to store messages on the servers and be secure at the same time (I'm not saying Telegram in particular is secure). I think it's more because Whatsapp's model is much cheaper on server expenses (they only need to store messages on the server until it's delivered).
- rodorgas 9y agoIt can be secure, but it's less secure by definition. While it's almost impossible to crack some cryptos, it's definitely impossible retrieve data that simply isn't there.
- fishywang 9y agoWhat I'm saying is I don't think Whatsapp designed it to be secure (P2P is more likely a byproduct of their design). They designed it to save server cost. After they are successful, it's straightforward to implement P2P crypto on that design, so they added that feature because they don't store the messages on server anyway.
- newscracker 9y agoWhatsApp is not strictly P2P and your belief that it doesn't store information on its servers, by claiming "it's definitely impossible retrieve data that simply isn't there", isn't true. It does store encrypted messages on its servers for up to 30 days while it attempts to deliver it.
