Sorry for being silent this morning, I just bought one of those simple and
insecure readers to play with. It is a REINER SCT cyber Jack RFID basis
Contactless Smartcard Reader.

On Windows, it uses Microsoft's Usbccid smartcard reader (WUDF) and as soon
as the "logincard" comes in play it the OWOK light 1.0 driver is installed
as well. 

For those interested in the XML version of the card (official comments in
English), it is here:

All API, protocol and architecture specific details (in English) are at the
end of the resource, which Henry mentioned already:

It looks like some details of the process for providing software that makes
use of the signature laws/components can be seen at the following:
the term "Herstellererklärung" can be understood as contract with government
- that the company applies the rules defined in the signature laws (SigG and

One of the products mentioned, applies: PKCS#7 detached, PKCS#7 enveloped
and PDF Signatures based on Adobe PDF V 1.6 adbe.pkcs7.detached

Based on the laws mentioned, they apply the hash-algorithms SHA-1/256/512
and RIPEMD-160 RSA  and for RSA with different key-length depending on the
year, so i.e. until end of 2007 1024-bit key were treated as secure, and
right now they think 1976/2048 bit key length can be seen as secure until

The CVCA certificate life cycle is described here:

Here it is also said, the certificate must meet the rules described in
TR03110 - in English here:

In general, looks like WebID could be possible (but obviously very
