Public Keys

My public keys for encryption, signing and authentication.

OpenPGP #

OpenPGP can be used for encryption of mail messages and files. I’m using it to digitally sign email messages, files and code commits.

Modern email client software, like Thunderbird, will retrieve the public key automatically, based on my email address.

To ensure that a key actually belongs to a specific person, the fingerprint should be checked. Ideally, this happens during a personal meeting.

SSH Public Key #

I use my OpenPGP key to authenticate against SSH servers too.

If you already have verified and trust my OpenPGP key, you can also safely trust my SSH key.

To allow me to access your systems trough SSH, you can export my OpenPGP key as SSH key:

# My user ID on your system (change as needed)
$ _SSH_USER=wolf

# Search and install my OpenPGP key
$ gpg --search-keys 0x722389E427362DC5

# Export and install my SSH key
$ gpg --export-ssh-key 0x722389E427362DC5 \
    | sudo -u $_SSH_USER tee -a /home/${_SSH_USER}/.ssh/authorized_keys

On Ubuntu Linux systems you can get my public key from either Launchpad or GitHub:

# Launchpad
ssh-import-id lp:awolf

# GitHub
ssh-import-id gh:alainwolf

Altenatively you can download my SSH public key:
