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.What benefits do smart cards capable of storing private keys, and devices like the YubiKey Neo (which seems to be a smart card + usb reader in a single dongle) offer above storing private keys on a plain-old usb thumb drive? Does the smart card ever "reveal" the private key to applications like SSH or GPG?
GnuPG comes with a tool to administrate smart cards and USB tokens. This tool is an enhanced version of the --edit-key command available with gpg. 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. This setup makes use of a Smartcard paired with a small form-factor Smartcard reader to effectively create an OpenPGP USB “token.” (Note: This reader does NOT have an external PIN pad for secure PIN entry, so if that’s a concern for .
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.In cryptography, the OpenPGP card [1] is an ISO/IEC 7816-4, -8 compatible smart card [2] that is integrated with many OpenPGP functions. Using this smart card, various cryptographic tasks ( encryption , decryption, digital signing/verification , authentication etc.) can be performed. Do any of you use SmartCards to store your GPG keys? I see a lot of tutorials out there on how to do it, but very little information on where to obtain compatible SmartCards. The few SmartCard sources I have found are mostly in Europe, and most of those seem to not have any or no longer offer them. GnuPG supports the use of hardware security tokens that come as smartcards (or USB devices that support this mode).
