Your key is stored in ~/.local/share/patatt, but you don't really need to do anything, Kees can do the following: b4 kr --show-keys 363b58690e907c677252467a94fe49444c80ea76.1649704381.git.christophe.leroy@csgroup.eu For now, this just provides instructions on what to do with the key: christophe.leroy@csgroup.eu: (unknown) keytype: ed25519 pubkey: HIzTzUj91asvincQGOFx6+ZF5AoUuP9GdOtQChs7Mm0= krpath: ed25519/csgroup.eu/christophe.leroy/20211009 fullpath: /home/user/.local/share/b4/keyring/ed25519/csgroup.eu/christophe.leroy/20211009 --- For ed25519 keys: echo [pubkey] > [fullpath] So, for Kees to start being aware of your key, he needs to do: mkdir -p /home/user/.local/share/b4/keyring/ed25519/csgroup.eu/christophe.leroy echo HIzTzUj91asvincQGOFx6+ZF5AoUuP9GdOtQChs7Mm0= > /home/user/.local/share/b4/keyring/ed25519/csgroup.eu/christophe.leroy/20211009 I know this is awkward and clunky right now. Future versions of b4 will streamline keyring management to make it a lot easier, I promise. -K
