Telegram received quite a backlash from crypto community for rolling out nonsensical throw-a-bunch-of-crypto-algorithms-together homebrew protocol that was designed by Math PhD™ students and having an audacity of conducting a contest to break it. This OTOH uses peer reviewed, strong, modern crypto that was designed by people who know how to do these things.

The crypto might be superior, but we do not know for sure that Whatsapp/Facebook is not covertly decrypting the messages and funneling through some Prism v2 NSA surveillance operation.

You can say say the same about Telegram, can you not?

it use the public key of the other user, not whatsapp. in effect, whatsapp is just acting as a key server. now they could have that users private key, but that's another matter

So in theory they could help by intercepting these keys and handing them to authorities without actually decryption the data themselves

the client generates a public/private key pair and only sends the public one to the whatsapp server. the server should never be able to access the private key. but unless the source of the client is available for review, who knows?

At least on smartphones yes, you can (by tapping on persons name during chat, and then selecting "Encryption").

I meant on S40.

Hazzah, you can! Shame they're only supporting s40 through the end of '16 :(
