To use Debian Live, download the latest image: This guide recommends using a bootable "live" Debian Linux image to provide such an environment, however, depending on your threat model, you may want to take fewer or more steps to secure it. Secure hardware/firmware ( Coreboot, Intel ME removed)ĭedicated air-gapped system with no networking capabilities Separate hardened Debian or OpenBSD installation which can be dual booted Virtual machine on daily-use host OS (using virt-manager, VirtualBox, or VMware) Here is a general ranking of environments most to least likely to be compromised: To create cryptographic keys, a secure environment that can be reasonably assured to be free of adversarial control is recommended. You will also need several small storage devices (microSD cards work well) for storing encrypted backups of your keys.

This website verifies YubiKey device attestation certificates signed by a set of Yubico certificate authorities, and helps mitigate supply chain attacks.

If you see Verification complete, the device is authentic. Touch the YubiKey when prompted, and if asked, allow it to see the make and model of the device.

Insert a Yubico device, and select Verify Device to begin the process. To verify a YubiKey is genuine, open a browser with U2F support to. In May 2021, Yubico also released a press release and blog post about supporting resident ssh keys on their Yubikeys including blue "security key 5 NFC" with OpenSSH 8.2 or later, see here for details. NEO models are limited to 2048-bit RSA keys.

Please see the Change PIN section for details on how to change your PINs. This would allow an attacker to use your Yubikey or reset your PIN. Security Note: If you followed this guide before Jan 2021, your GPG PIN and Admin PIN may be set to their default values ( 12345678 respectively).

New! drduh/Purse is a password manager which uses GPG and YubiKey. All signing and encryption operations happen on the card, rather than in OS memory. Instead of having to remember and enter passphrases to unlock SSH/GPG keys, YubiKey needs only a physical touch after being unlocked with a PIN. Keys stored on YubiKey are non-exportable (as opposed to file-based keys that are stored on disk) and are convenient for everyday use. Many of the principles in this document are applicable to other smart card devices. This is a guide to using YubiKey as a SmartCard for storing GPG encryption, signing and authentication keys, which can also be used for SSH.
