When encrypting or decrypting documents on a computer that isn't my daily driver I need to import my key to the keychain, do the encrypt/decrypt then remove the keychain and from the computer. As a security considering person I know that still leaves the key on the computer whether indexed or not, so it can be recovered.
Is there any way to encapsulate all the functionally of a GnuPG keychain but on a portable USB stick.
This way when you are done with encrypting/decrypting you can just remove the USB.
Like a Yubico stick but with GnuPG private and public keys on.
