The last class of security, some colleagues made a presentation about cryptography which was pretty interesting because we learned some new things like the public and private key and how they work so that you can send data in a very secure way. We used an application called Keybase which is a secure chat based on GPG which is based on the RSA algorithm. This gives you the confidence that no one’s going to see what you are talking except the other person you are talking to.
