token-status-list 0.1.0a2.dev0

Implementation of IETF Token Status List

token-status-list

This is an implementation of Token Status List Draft 2.

Features

• Support for 1, 2, 4, and 8 bits.
• Compression as required by the Specification (ZLIB at level 9)
• Formatting and signing Status Lists as either JWT or CWT
  • A TokenSigner protocol is defined so the user can Bring Their Own Crypto implementation
  • Alternatively, methods for preparing payloads and assembling payload and signature bytes into the final token is also supported.
• Two Index Allocation strategies, Linear and Random
  • Linear strategy will allocate indices serially
  • Random strategy will allocate indices pseudo-randomly (as the list fills, speed is favored over randomness)
  • Allocators contain state that must be persisted along side the status list itself
  • IssuerStatusList and Allocators are serializeable so the user can persist them to the backend of their choice

Planned Features

These are features that I intend to include soon.

• VerifierStatusList providing helpers to verify and validate a Status List Token obtained for verification.
• Examples
