Ok I apologize for my ignorance as I've been desperate for help with not many places to turn to. Thank you very much

Ah man. So let me ask you for clarification in case I am not understanding this right. You're saying I encrypted the message with someone else's public key?

I included two pictures of what is going on. The first picture is what I get from trying to decrypt the line that you gave me. The second picture is the original issue I was having. I do appreciate your help

I also have had this problem. I just opened up my laptop for the first time in years. I was trying to decrypt text I encrypted years ago but I get that same error stated in the original post. Now I just remind you, this was encrypted years ago. In the encrypted message, after it says "begin pgp message," it says "version: GnuPg v2.0.20 (MingW32)" i am not sure if that matters, but that is all i have to give on my end other than i am currently using gpa 0.9.10 GnuPG 2.2.3
