Export existing private ssh key to OpenPGP card or Yubikey

Before you begin

This will only work with OpenPGP v2.0 or newer or with PIV cards. Your existing ssh key has to be in a format that is supported by your opengpg card. For example my the OpenPGP V2.1 Card from FLOSS Shop supports only 2048 bit RSA keys. RSA exponent should be 65537, Putty and old OpenSSH releases use different expnent that for example Yubikey does not support.

Converting openssh private key format to pem

man page says that you can use -e option to convert private and public keys to other formats, that seems to be wrong. Instead you can use -p option to request changing the password but not actually setting the password.

ssh-keygen -p -f id_rsa -m pem

Converting pem to OpenPGP

Monkeysphere project includes a pem2openpgp command that can be used to import ssh private keys to gnupg keyring.

Wireguard autmatic configuration ideas

Collection of ideas for automatic wireguard interface configuration

Generating ipv6 aadresses

• Interface gets a link local ip like so fe80::hash(interfacepubkey)/64
• Each peer allowed ips get fe80::hash(peerpubkey)/128
