This script helps you to read, create and modify Legic Prime Tags (MIM22, MIM256, MIM1024)
it's kinda interactive with following commands in three categories:
- Data I/O Segment Manipulation File I/O
------------------- -------------------- ---------------
- rt => read Tag ds => dump Segments lf => load File
- wt => write Tag as => add Segment sf => save File
- es => edit Segment xf => xor File
- ct => copy io Tag ed => edit Data
+ Data I/O Segment Manipulation Token-Data
+ ----------------- -------------------- -----------------
+ rt => read Tag as => add Segment mt => make Token
+ wt => write Tag es => edit Segment Header et => edit Token data
+ ct => copy io Tag ed => edit Segment Data tk => toggle KGH-Flag
tc => copy oi Tag rs => remove Segment
- di => dump inTag cc => check Segment-CRC
- do => dump outTag ck => check KGH
- tk => toggle KGH-Flag
- mt => make Token
- q => quit et => edit Token h => this Help
+ cc => check Segment-CRC File I/O
+ di => dump inTag ck => check KGH -----------------
+ do => dump outTag lf => load File
+ ds => dump Segments sf => save File
+ lc => dump Legic-Cash xf => xor to File
+ d3p => dump 3rd Party Cash
+ r3p => raw 3rd Party Cash
+
- Data I/O
rt: 'read tag' - reads a tag placed near to the PM3
wt: 'write tag' - writes the content of the 'virtual inTag' to a tag placed near to th PM3
without the need of changing anything - MCD,MSN,MCC will be read from the tag
tc: 'copy tag' - copy the 'second virtual Tag' to 'virtual TAG' - not usefull yet, but inernally needed
di: 'dump inTag' - shows the current content of the 'virtual Tag'
do: 'dump outTag' - shows the current content of the 'virtual outTag'
-
- Segment Manipulation
- (all manipulations happens only in the 'virtual inTAG' - they need to be written with 'wt' to take effect)
ds: 'dump Segments' - will show the content of a selected Segment
as: 'add Segment' - will add a 'empty' Segment to the inTag
es: 'edit Segment' - edit the Segment-Header of a selected Segment (len, WRP, WRC, RD, valid)
'Kaba Group Header CRC calculation'
tk: 'toggle KGH' - toglle the (script-internal) flag for kgh-calculation for a segment
xc: 'etra c' - show string that was used to calculate the kgh-crc of a segment
-
- Input/Output
+dlc: 'dump Legic-Cash' - show balance and checksums of a legic-Cash Segment
+d3p: 'dump 3rd Party' - show balance, history and checksums of a (yet) unknown 3rd Party Cash-Segment
+r3p: 'raw 3rd Party' - show balance, history and checksums of a (yet) unknown 3rd Party Cash-Segment
+e3p: 'edit 3rd Party' - edit Data in 3rd Party Cash Segment
lf: 'load file' - load a (xored) file from the local Filesystem into the 'virtual inTag'
sf: 'save file' - saves the 'virtual inTag' to the local Filesystem (xored with Tag-MCC)
xf: 'xor file' - saves the 'virtual inTag' to the local Filesystem (xored with choosen MCC - use '00' for plain values)
