scll-core

Core crate of the Simple Card Lifecycle Library (scll): transport and backend traits, GlobalPlatform command builders/parsers, SCP02/SCP03 secure channel state machines (state only — crypto is delegated to a backend), and a CAP file parser.

  • no_std + alloc-free (fixed-capacity heapless buffers); MSRV 1.81.
  • No concrete transport and no concrete cryptography: implement Transport and the split backend traits (KeyBackend, Scp02Backend, Scp03Backend, optional ExportableKeyBackend), or use the shipped implementations via the scll facade crate.
  • Opaque KeyHandles throughout the public API — key material never crosses the API as bytes (HSM/PKCS#11-friendly).
  • Baseline specs: GlobalPlatform Card Specification v2.3.1, Amendment D v1.1.2 (SCP03), Amendment E v1.0.1 (SCP02).
