Pinpad Input Support

It is possible to input the PIN (your passphrase) by using a card reader's pinpad (if available).

However, using it with OpenPGP card, you have to do some configuration work. This is because of a glitch between the specification of OpenPGP card and existing card readers implementations. In the specification, its passphrase is defined as variable length. Unfortunately, there are some card readers which don't support variable length pinpad input, and there is *no standard way* to distinguish whether a card reader supports variable length pinpad input or not.

If your card reader supports variable length pinpad input, fine. Please add the following configuration line:

  enable-pinpad-varlen

If not, you need to write "login" data object to specify PIN length in a specific way. Please see CardReader/GemaltoPC.

List of card readers which support pinpad input with variable length

For known card readers, you can omit the configuration above. The list is coded in scd/apdu.c (for PC/SC service) and scd/ccid-driver.c in GnuPG.
