OpenPGP card

From Wikipedia, the free encyclopedia

In cryptography, the OpenPGP card [1] is an ISO 7816-4, -8 compatible smart card [2] 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.

Built on BasicCard [3], OpenPGP cards can be obtained from vendors [4] or by becoming a fellow in Free Software Foundation Europe [5].

The smart card daemon, in combination with the supported smart card readers [6], as implemented in GnuPG, can be used for many cryptographic applications. With gpg-agent in GnuPG 2, an ssh-agent implementation using GnuPG, an OpenPGP card can be used for SSH authentication also.
