gpg2 smart card Unfortunately, despite existing for over a decade, it’s been difficult to find comprehensive information about setting up and using smart cards, for use with GPG and SSH, under Linux, Windows and OSX. This article is heavily based on “ Offline GnuPG Master Key and Subkeys on YubiKey NEO Smartcard ” by Simon Josefsson. NFC can be used to read tags and for Apple Pay. To use, make sure your iPhone is unlocked, and then tap the top of your iPhone's back on the tag to get a pop-up. Unfortunately, .

Figure out where your phone's NFC antenna is and hold it there. If it does not pick up after a second or so of holding it there, remove it and put it there again. Moving it around on the device may or may not work. Turns out that holding it at 45 .
For day-to-day use I chose the Yubikey Neo. I’ve LOVED the Yubikey product line for years because they are clever, small, versatile, and indestructible. I bought mine from Amazon for . They support various OTP schemes, OpenPGP smart card, and Fido U2F. The Yubikey is a authentication swiss-army knife. One . See more

The gpg-card is used to administrate smart cards and USB tokens. It provides a superset of features from gpg --card-edit an can be considered a frontend to scdaemon which is a daemon started by gpg-agent to handle smart cards.
The OpenPGP Card is an ISO/IEC 7816-4/-8 compatible smart card implementation that is integrated with many GnuPG functions. Using this smart card, various cryptographic tasks (encryption, decryption, digital signing/verification, authentication etc.) can be performed. First, make sure you're running GnuPG 2.x. This is important because you can't use 4096-bit RSA keys on most smartcards with GnuPG 1.x. A Bash alias will suffice, i.e. alias gpg=gpg2. If you use the Enigmail Thunderbird add-on, make sure the GPG path to /usr/bin/gpg2.

Using GPG with Smart Cards
GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC 4880 (also known as PGP). GnuPG allows you to encrypt and sign your data and communications; it features a versatile key management system, along with access modules for . Specifically, the Gnuk implements the OpenPGP v2 smart card protocol for STM32F103. An FST-01 , for example, can be purchased for around -40. Ultimately, you’ll need to decide who you trust, and what device meets your needs best, but hopefully this gives you a start to see what’s out there. I have created an offline MASTER key along with sub keys. The sub keys were sent to the Yubikey smartcard via the gpg 'keytocard'. The gpg --card-status command correctly identifies the information showing the masterkey id as well as the sub keys. I .To create an OpenPGP key from the keys available on the currently inserted smartcard, the special string “card” can be used for algo. If the card features an encryption and a signing key, gpg will figure them out and creates an OpenPGP key consisting of the usual primary key and one subkey. This works only with certain smartcards.
In order to use your smart card on another computer you basically need two things, provided that you have a properly configured card reader: import the public key to your keyring insert the smart card into the reader then run gpg2 --card-status to create the stub, that is a pointer to the card for the given GPG keyI configured gpg2 to use my signature key in smartcard gnupg V2.0. I imported my gpg signature key to the rpm store. I need to sign an rpm package using rpm --addsign myApp.rpm. It works fine, but rpm prompts once for the smartcard PIN, and gpg2 (with pinentry programm) prompts three times for the smartcard PIN.
