Given that this is asymmetric cryptography with private/public key, I am not sure if reduced bit length is breakable easier than longer keys. I understand that the key population is reduced (hence randomness, hence brute force) however, I am still wondering, does this mean it is easily breakable? Are there any studies/research/cryptanalysis performed to measure what this mean?
The site I am referring to here is web.Whatsapp.com
India wants social media sites such as Whatsapp to make the content accessible by Government (because of hatred spread on social media that led to people being lynched!). Is it possible that the public key size is purposefully reduced to accommodate this?
I got a VPN through US and verified it is 256 bits for accessing in US too. So, is it possible that WhatsApp is not as secure as we think?
