It is recommended to generate cryptographic keys and configure YubiKey from a secure environment to minimize exposure. This website verifies the YubiKey's device attestation certificates signed by a set of Yubico CAs, and helps mitigate supply chain attacks. If you see Verification complete, your device is authentic. Touch the YubiKey when prompted, and if asked, allow it to see the make and model of the device. Insert your Yubico device, and click Verify Device to begin the process. To confirm your YubiKey is genuine open a browser with U2F support and go to. See Compare YubiKeys.Ĭonsider purchasing a pair of YubiKeys, programming both, and storing one in a safe secondary location, in case of loss or damage to the first key. NEO models are limited to 2048-bit RSA keys. (Optional) Save public key for identity file configurationĪll YubiKeys except the blue "security key" model are compatible with this guide.If you have a comment or suggestion, please open an issue on GitHub. 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 code. 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.
