Possible enhancement to OpenPGP card specification 2.0.1 | GnuPG supports the use of hardware [[https://en.wikipedia.org/wiki/Security_token|security tokens]] that come as smartcards. The smartcards are minicomputers that can hold the secret key material and perform crypto operations. Because you need to connect the physical "token" to your machine, the secret key material is well protected against attacks that try to steal it. |
