Sorry if this has been mentioned, I have attempted to search for the answer to this on and off for a few weeks, but I've had no luck. After dealing with venders who specifically ask for you to not sign PGP messages, I've come to wonder- is sending your public key necessary in this case? As long as it's encrypted to their public key, do they have to have yours?
Once again, sorry if this is common knowledge, I've tried to find the answer and posting this question was pretty much my last resort.
Thanks!
They only need your public key if they are going to encrypt a message to you.
You should put your public key in your profile, just in case.
