has denied reports that encrypted messages on its platform can be read or intercepted, saying that since April 2016, WhatsApp
messages and calls are end-to-end encrypted by default.
A security vulnerability that can be used to allow Facebook and others
to intercept and read encrypted messages has been found within its WhatsApp messaging
service, The Guardian
reported on Friday.

is false. WhatsApp
does not give governments a 'backdoor' into its systems. WhatsApp
would fight any government request to create a backdoor," said Brian Acton, Co-founder WhatsApp, in a Reddit
has published a technical white paper explaining its implementation of end-to-end encryption.
The security issue was detected by Tobias Boelter, a cryptography
and security researcher.

records, it can effectively grant access due to the change in keys," The Guardian
quoted Boelter as saying.
said it was designed to be simple and they had built end-to-end encryption, with encryption
as the default so that not a single one of their one billion users has to turn on encryption.
"The fact that WhatsApp
handles key changes is not a 'backdoor', it is how cryptography
works. Any attempt to intercept messages in transmit by the server is detectable by the sender, just like with signal, PGP, or any other end-to-end encrypted communication system," said Moxie Marlinspike, who designed WhatsApp's encryption, in a blog.
