More about gnupg-pkcs11-scd:

gnupg-pkcs11 is a project to implement a BSD-licensed smart-card daemon to enable the use of PKCS#11 tokens with GnuPG. The motivation behind this project originates in the following two threads:

• http://lists.gnupg.org/pipermail/gnupg-users/2006-February/027964.html
• http://lists.gnupg.org/pipermail/gnupg-devel/2004-November/021522.html
• http://lists.gnupg.org/pipermail/gnupg-users/2004-November/023673.html

PKCS#11 is the de-facto standard for accessing cryptographic tokens, and thus we strongly disagree with WK’s attitude towards it.
