After reading the explanation in this page https://github.com/kontalk/androidclient/wiki/The-personal-key about the personal key, I think I have a better understanding on the process around The Personal Keys and encryption.
I will like to make sure I’m understanding things correctly though:
So I’m thinking on making some business card for my friends and let them now they can find me in kontalk, and I thought that maybe I could add my public key’s fingerprint on them.
At first I wasn’t so sure if this was alright. When ever I read that, to be safe, you should share your public fingerprint to others in another way other than a kontalk message, I thought this was because giving away you fingerprint meant some one could use it to take your identity.
Now that I have read about it, I think that the public fingerprint is already just that, public, and anybody can see it already. The reason I believe sharing it through kontalk is not suggested is that it wouldn’t prove it’s really you who is sending the message.
Am I right on my conclusions? Would it be alright for me to share my public fingerprint on my business cards?
Thank you.
