|
|
<a id="top"></a>
|
|
|
|
### EMV Implemented parts:
|
|
|
|
- Get ATR|ATS
|
|
- Get AID by PSE (`emv pse`)
|
|
- Get AID by application list (`emv search`)
|
|
- Select application (`emv select`)
|
|
- Format PDOL (look at next part)
|
|
- Execute GPO (`emv gpo` this step and format PDOL)
|
|
- Get records from AFL (`emv readrec`)
|
|
- Make SDA (check records from GPO)
|
|
- Make DDA (`emv challenge` `emv intauth`)
|
|
- Check PIN (`not implemented`)
|
|
- Fill CDOL1 and CDOL2 (look at next part)
|
|
- Execute AC1 (with CDA support) (`emv genac`)
|
|
- Check ARQC (bank part) (`not implemented`)
|
|
- Make ARPC (bank part) (`not implemented`)
|
|
- Execute external authenticate (`not implemented`)
|
|
- Execute AC2 (with CDA support) (`not implemented`)
|
|
- Check ARQC cryptogram (`not implemented`)
|
|
- Issuer scripts processing (`not implemented`)
|
|
|
|
### Working parts of qVSDC:
|
|
^[Top](#top)
|
|
|
|
- Get ATR|ATS
|
|
- Get AID by PSE (`emv pse`)
|
|
- Get AID by application list (`emv search`)
|
|
- Select application (`emv select`)
|
|
- Format PDOL (look at next part)
|
|
- Execute GPO (`emv gpo` this step and format PDOL)
|
|
- Get records from AFL (`emv readrec`)
|
|
- Make fDDA (`emv challenge` `emv intauth`)
|
|
- External authenticate command (`not implemented`)
|
|
- Issuer scripts processing (`not implemented`)
|
|
|
|
### `not implemented` parts of EMV
|
|
^[Top](#top)
|
|
|
|
They can be implemented, but it needs to know issuer's card keys (usually 3DES) and now this parts can be tested only on special test cards.
|
|
|
|
### Commands
|
|
^[Top](#top)
|
|
|
|
All this commands are parts of command `emv exec`.
|
|
command `emv exec` executes EMV transaction. it have parameters:
|
|
```
|
|
-j, -J, --jload Load transaction parameters from `emv/defparams.json` file.
|
|
-f, -F, --forceaid Force search AID. Search AID instead of execute PPSE.
|
|
By default: Transaction type - MSD
|
|
-v, -V, --qvsdc Transaction type - qVSDC or M/Chip.
|
|
-c, -C, --qvsdccda Transaction type - qVSDC or M/Chip plus CDA (SDAD generation).
|
|
-x, -X, --vsdc Transaction type - VSDC.
|
|
-g, -G, --acgpo VISA. generate AC from GPO.
|
|
-w, -W, --wired Send data via contact (iso7816) interface. Contactless interface set by default.
|
|
```
|
|
It works for VISA(r) and Mastercard(r) transactions. It may work with other EMV payment system's card (and it works in general cases that is described in EMV).
|
|
|
|
### VISA(r) transactions:
|
|
^[Top](#top)
|
|
|
|
MSD - Magnetic Stripe mode
|
|
VSDC - contact transaction
|
|
qVSDC - contactless transaction
|
|
|
|
### Mastercard(r) transactions
|
|
^[Top](#top)
|
|
|
|
MSD - Magnetic Stripe mode
|
|
M/Chip - contact and contactless transaction
|
|
|
|
Different cards have different modes on/of and different behavior in them. So needs to check card in all this modes.
|
|
MSD - compatibility mode. Now it work always. But it less secure and in near future it will be slowly) disabled.
|
|
|
|
### all commands:
|
|
^[Top](#top)
|
|
|
|
```
|
|
exec Executes EMV contactless transaction.
|
|
pse Execute PPSE. It selects 2PAY.SYS.DDF01 or 1PAY.SYS.DDF01 directory.
|
|
search Try to select all applets from applets list and print installed applets.
|
|
select Select applet.
|
|
gpo Execute GetProcessingOptions.
|
|
readrec Read files from card.
|
|
genac Generate ApplicationCryptogram.
|
|
challenge Generate challenge.
|
|
intauth Internal authentication.
|
|
scan Scan EMV card and save it contents to json file for emulator.
|
|
test Crypto logic test.
|
|
list List ISO7816 history
|
|
roca Extract public keys and run ROCA test
|
|
```
|
|
|
|
All main commands are parts of EMV specification. Commands than not described there:
|
|
|
|
`emv scan` - scans card and saves all records to json file. Can be executed with or without tags disassembly.
|
|
|
|
`emv roca` - extract public keys from cards (part of `emv scan`)
|
|
|
|
`emv test` - test all crypto code from emv part of proxmark.
|

### EMV kernels
|
|
^[Top](#top)
|
|
|
|
POS terminal checks card and selects one of EMV kernels and launches it for EMV transaction. Different kernels have different rules to make EMV transaction.
