Symmetric encryption does not require the generation of a key pair and can be used to simply encrypt data with a passphrase. See GNOME/Keyring#Disable keyring daemon components on how to disable this behavior. Copyright © 2002-2021 Judd Vinet, Aaron Griffin and Each key To avoid this kind of error, you have to trusts thoses keys. These files are copied to ~/.gnupg the first time gpg is run if they do not exist there. When the new user is added in system, files from here will be copied to its GnuPG home directory.

Your missing keys can be recovered with the following commands: If gpg hanged with a certain keyserver when trying to receive keys, you might need to kill dirmngr in order to get access to other keyservers which are actually working, otherwise it might keeping hanging for all of them. Then use udev rules, similar to the following: One needs to adapt VENDOR and MODEL according to the lsusb output, the above example is for a YubikeyNEO. Mutt might not use gpg-agent correctly, you need to set an environment variable GPG_AGENT_INFO (the content does not matter) when running mutt. Turn on suggestions. We have created the key pair in the local system. Please read GnuPG invalid packet workaround[dead link 2020-02-24]. The equivalent is true with /dev/pts/. Other clients like OpenSC PKCS#11 that are used by browsers and programs listed in Electronic identification are using PCSC_SHARE_SHARED that allows simultaneous access to single smartcard. The option auto-key-locate will locate a key using the WKD protocol if there is no key on the local keyring for this email address. The existence of these poisoned certificates in a keyring causes gpg to hang with the following message: Possible mitigation involves removing the poisoned certificate as per this blog post. By default, for OpenSSH, the public key needs to be concatenated with ~/.ssh/authorized_keys. is held by a different developer.
