In cryptography, 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.
Built on BasicCard, OpenPGP cards can be obtained from a vendor or by becoming a fellow in Free Software Foundation Europe.
The smart card daemon, in combination with the supported smart card readers, 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.
With Aloaha there is also a commercial middleware for Windows available.
Famous quotes containing the words open and/or card:
“Speech and silence. We feel safer with a madman who talks than with one who cannot open his mouth.”
—E.M. Cioran (b. 1911)
“In the game of “Whist for two,” usually called “Correspondence,” the lady plays what card she likes: the gentleman simply follows suit. If she leads with “Queen of Diamonds,” however, he may, if he likes, offer the “Ace of Hearts”: and, if she plays “Queen of Hearts,” and he happens to have no Heart left, he usually plays “Knave of Clubs.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
