I can't decrypt older files and email messages any more, and I can't even add [S] subkeys to the old key because of some weird SHA1 signature that keeps popping up :ablobcatcry:
I've spent the last four hours tinkering with all this, but I think there is no escape and no cure and all is lost, forever :/
Starting today, I have new #OpenPGP keys. Here's my transition statement: https://gist.github.com/kytta/781b7d0f9cf45d75c73f6b9746e86abb
0xD397E9BE9E6898FA is also up on the OpenPGP's keyserver and #Keyoxide.
I have quintuple-checked that my backups work now, so let's hope something like this will not happen again :ageblobcat:
