One of the best vendors around has changed their pgp key on all marketplaces without any warning or change of vendor page info saying so. Have people come across this before and does it have any significance? Vendor has always been legit and has a long dnm history so i would have no reason to ever doubt them usually. I will not name the vendor as I have not approached them about the issue and would certainly not name them unless I give them a chance at explaining what happened.
EDIT: Vendor has offered to decrypt a message using old pgp key and updated pgp software due to a bad review of the pgp software they were using. I am officially calling this FUD. Vendor seems legit as ever, i got his package so all is good.
Proper procedure is to sign the new key with they old one. Did they not do this?
