I'm currently using GPG. Every time I try to import a key from a .txt file in my home folder it tells me no keys were found. Is there a specific file type I should save the key as? Or is there a way to import it from plaintext?
EDIT: I FIGURED IT OUT. I used the same filetype that I saved my public key as. Thanks for the help guys!
Save it as a .asc file and open it that way.
