/* The German signature law and its bylaw (SigG and SigV) is currently
|

used with an interface specification described in DIN V 66291-1.
|

The AID to be used is: 'D27600006601'.
|
||||
|
||||
The file IDs for certificates utilize the generic format:
|
||||
Cxyz
|
||||
C being the hex digit 'C' (12).
|
||||
x being the service indicator:
|
||||
'0' := SigG conform digital signature.
|
||||
'1' := entity authentication.
|
||||
'2' := key encipherment.
|
||||
'3' := data encipherment.
|
||||
'4' := key agreement.
|
||||
other values are reserved for future use.
|
||||
y being the security environment number using '0' for cards
|
||||
not supporting a SE number.
|
||||
z being the certificate type:
|
||||
'0' := C.CH (base certificate of card holder) or C.ICC.
|
||||
'1' .. '7' := C.CH (business or professional certificate
|
||||
of card holder.
|
||||
'8' .. 'D' := C.CA (certificate of a CA issue by the Root-CA).
|
||||
'E' := C.RCA (self certified certificate of the Root-CA).
|
||||
'F' := reserved.
|
||||
|
||||
The file IDs used by default are:
|
||||
'1F00' EF.SSD (security service descriptor). [o,o]
|
||||
'2F02' EF.GDO (global data objects) [m,m]
|
||||
'A000' EF.PROT (signature log). Cyclic file with 20 records of 53 byte.
|
||||
Read and update after user authentication. [o,o]
|
||||
'B000' EF.PK.RCA.DS (public keys of Root-CA). Size is 512b or size
|
||||
of keys. [m (unless a 'C00E' is present),m]
|
||||
'B001' EF.PK.CA.DS (public keys of CAs). Size is 512b or size
|
||||
of keys. [o,o]
|
||||
'C00n' EF.C.CH.DS (digital signature certificate of card holder)
|
||||
with n := 0 .. 7. Size is 2k or size of cert. Read and
|
||||
update allowed after user authentication. [m,m]
|
||||
'C00m' EF.C.CA.DS (digital signature certificate of CA)
|
||||
with m := 8 .. E. Size is 1k or size of cert. Read always
|

allowed, update after user authentication. [o,o]
|

'C100' EF.C.ICC.AUT (AUT certificate of ICC) [o,m]

'D000' EF.DM (display message) [-,m]

Return the serial number of the card using a status reponse. This

|

|

If APPTYPE is given, an application of that type is selected and an

error is returned if the application is not supported or available.
|

The default is to auto-select the application using a hardwired

preference system. Note, that a future extension to this function

may allow to specify a list and order of applications to try.
|

This function is special in that it can be used to reset the card.

been detected and the use of this function is therefore required.
