+This repo describes my P.I.S. (**P**oliciy for **I**nternal **S**ecurity).
+You'll find my personal guidelines for SSH / GPG on YubiKey and how to configure and create a key / certificate.
 
-I have a several Yubikey, each with different purpose. 
-- **Master Yubikey:** A Yubikey 5C that keep Master GPG, SSH CA and root CA for my server. This Yubikey stay in secure place and will be use only to sign sub-key, new SSH Key or new IC.
-- **Keyring Yubikey:** A Yubikey 5C NFC on my keyring. This Yubikey is used to keep some passkeys and TOTP for some app. This also contain GPG subkey and ssh key signed by SSH CA on Master Yubikey.
-- **Laptop Yubikey:** A small Yubikey 5 Nano in my laptop that contain GPG sub-key and a ssh key like Keyring Yubikey. This Yubikey Nano stay mostly on my laptop. It slightly increse the security compare to have gpg and ssh directly on my laptop.
-- **Backup Yubikey:** A Yubikey 5C, keep in secure place that contains the same passkey and TOTP that the Keyring Yubikey. As security depend of the weekest security measure, some of my apps have passkey enforced or TOTP on Yubikey only. This backup key prevents from loosing acces in case of lose the Keyring Yubikey.
