Versioning

Package Version

This package uses a form of semantic versioning. The version number is comprised of three components: MAJOR.MINOR.PATCH

Major version numbers represent breaking internal API changes. You may need to modify your code to accomodate these changes. Minor version numbers represent feature additions or changes that do not break the library's API, and are fully backward compatible. Patch version numbers represent bug fixes or minor changes that do not add additional functionality.

The package version is independent of the Nexus System Version that the package supports.

Usage

Generate keycodes for the full and small keypad protocols.

Full Protocol

Add Credit

secret_key = b"\xde\xad\xbe\xef" * 4
message = FullMessage.add_credit(
    id_=42, hours=24 * 7, secret_key=secret_key
).to_keycode()
# outputs *599 791 493 194 43#

Set Credit

message = FullMessage.set_credit(
    id_=43, hours=24 * 10, secret_key=secret_key
).to_keycode()
# outputs *682 070 357 093 12#

Unlock

message = FullMessage.unlock(id_=44, secret_key=secret_key).to_keycode()
# outputs *578 396 697 305 45#

Wipe

message = FullMessage.wipe_state(
    id_=45, flags=FullMessageWipeFlags.WIPE_IDS_ALL, secret_key=secret_key
).to_keycode()
# outputs *356 107 776 307 38#

Enabled/Disabled Test

message = FactoryFullMessage.oqc_test().to_keycode()
# outputs *577 043 3#

Factory Test

message = FactoryFullMessage.allow_test().to_keycode()
# outputs *406 498 3#

Display PAYG ID

message = FactoryFullMessage.display_payg_id().to_keycode()
# outputs *634 776 5#

Small Protocol

Add Credit

SECRET_KEY = b"\xde\xad\xbe\xef" * 4
AddCreditSmallMessage(id_=42, days=7, secret_key=secret_key).to_keycode()
# outputs 135 242 422 455 244

Update Credit

UpdateCreditSmallMessage(id_=43, days=14, secret_key=secret_key).to_keycode()
# outputs 145 222 453 233 453

Set Credit

SetCreditSmallMessage(id_=44, days=10, secret_key=secret_key).to_keycode()
# outputs 142 522 332 234 533

Unlock

UnlockSmallMessage(id_=45, secret_key=secret_key).to_keycode()
# outputs 152 323 254 454 322

Wipe

MaintenanceSmallMessage(type_=MaintenanceSmallMessageType.WIPE_IDS_ALL, secret_key=secret_key).to_keycode()
# outputs 122 324 235 545 545
