Key Verification in Secure Messaging with Bit Security

Or how can I know you are who you say you are?

By Joël Alwen

There are many things cryptography solves when it comes to ensuring the integrity and privacy of user connection — from protecting the content of communications so only intended recipients can decrypt them to authenticating the parties to multi-actor transactions. One of the coolest things crypto enables is ensuring that a person I think I am talking to is exactly who I think it is, even if they are thousands of miles away and I’ve never met them. I want to share our thinking about key verification design and ways we implement it to help our users across Wickr apps to authenticate their contacts.
