I was filling in a pdf and it asked me if I'd like to sign it digitally and then save the digital signature. Since then I can't acess my mail on my MacBook, it keeps coming up with this. How do I delete all digital signature files from my laptop?I can't get rid of this and have to force quit mail.

@gunzelguy oh wow, I hav never had that happened before...not sure why your Mac stored a encryption key in your Keychain! Did you accidentally clicked on a key that use this signature for all your secure communications? 

You might need to use Spotlight (Command Spacebar) for this and type in Keychain Access. Once you hit enter, the Keychain Access will automatically open. In this case, you are looking for the Imported Private Key. Locate it and select it. Right-click it, and delete Imported Private Key. There will also be a certficate as well for the Imported Private Key which should also be removed too. Under Certificates, it would have been created the same time when you signing the PDF with your name and email address, with a red icon, Right-click it, and delete it as well.

Thank you so much, that worked perfectly and my mail is back to normal. For some reason I can’t get back to your post on the Adobe Forums.

Thank you again
