I just made a small first-time purchase from a vendor I've never used before but one that has a good rep on Abraxas and Agora and everything seemed fine until I sent over my encrypted info via PGP. Here is the exchange that occurred:
Him: Hey your pgp didnt work...try using sms4tor (gave me the link)
Me: Hey, I'm resending PGP using the key from your profile:
Him: It still didn't work...I don't know why because I know you have ordered before
Me: I haven't ordered from you before, this is my first time. Can you send me your public key again here so I can re-import it and try again?
Him: I think our 2 pgp programs are not compatible...This happened last week to me also
So, this seems super not-legit to me and I want to make sure that I am not crazy. The only real plausible reason that someone wouldn't be able to decrypt your info using the public key on their profile is because it probably isn't them on that account anymore, correct?
Correct
Although, I'd double check everything is formatted correctly and your PGP software is up to date just to make sure. (Which it seems like you've done)
