/* 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 ard 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 uder authentication. [o,o]
'C100' EF.C.ICC.AUT (AUT certificate of ICC) [o,m]
'C108' EF.C.CA.AUT (AUT certificate of CA) [o,m]
'D000' EF.DM (display message) [-,m]
The letters in brackets indicate optional or mandatory files: The
first for card terminals under full control and the second for
"business" card terminals.
FIXME: Needs a lot more explanation.
