+## export and backup keys
+
+Now we would like to export and backup private and public keys
+
+start by listing key with keygrip:
+```
+gpg --keyid-format long --with-fingerprint --list-key
+```
+
+then export keys:
+```
+gpg --export --armor --output public-key.asc < key id >
+gpg --export-secret-keys --output secret-key.asc < key id >
+```
+
+## yubikey configure
+
+default admin pin: 12345678
+default pin: 123456
+
+entrer admin  mode:
+```
+gpg --card-edit
+admin
+kdf-setup
+passwd

+lang
+login
+list
+quit

+
+## send keys
