• gp.jar (Java)

• JavaCard (JCOP recommended)

Exact Step-by-Step Setup & Usage (Copy-Paste Commands)​

1. Basic Card Connection & Info

# List readers
java -jar gp.jar --list
# or gp.exe --list (Windows)

# Connect and show card info
java -jar gp.jar -i
# or gp.exe -i

# Expected output for JCOP 160K v2.4.2 R3:
ISD: A000000151000000 (OP_READY)
ATR: 3B F9 18 00 00 81 31 FE 45 4A 43 4F 50 76 32 34 32 52 33 B7

2. Authenticate (Open Secure Channel)
Default test keys (40..4F) – most unfused/test JCOP cards:

gp --unlock
# or with custom keys
gp -key ENC:404142434445464748494A4B4C4D4E4F -key MAC:404142434445464748494A4B4C4D4E4F -key KEK:404142434445464748494A4B4C4D4E4F --unlock

3. List Installed Applets

gp -l
# Sample output:
ISD: A000000151000000 (OP_READY)
Applet: A0000001515350 (LOADED)
Package: A00000015153 (LOADED)

4. Install Applet (CAP File)

gp --install HelloWorld.cap
# With privileges and parameters
gp --install HelloWorld.cap --default --priv 04 --param 00

5. Delete Applet

gp --delete A048656C6C6F576F726C64
# Delete package + applet
gp --uninstall HelloWorld.cap

6. Lock / Unlock Card

gp --lock 404142434445464748494A4B4C4D4E4F
gp --unlock 404142434445464748494A4B4C4D4E4F

7. Advanced – Change Keys

gp --secure-channel
gp --put-key -new-key 0102030405060708090A0B0C0D0E0F10 -keyver 1

Real JCOP-Specific Examples (2025)​

Unfused JCOP Initialization (common for blank cards):

gp --unlock
gp --install-for-load JCOPManager.cap

Force EMV Diversification (some JCOP):

gp --emv --unlock

Verbose Debug Mode:

gp -v -d -i
