Crate nostr_bbs_core 

Shared Nostr protocol primitives for the nostr-bbs forum.

This crate provides the cryptographic and protocol building blocks shared between the WASM client bridge and the Rust Cloudflare Workers. It covers:

• NIP-01 event creation, signing, and verification
• NIP-44 encrypted direct messages (ChaCha20-Poly1305)
• NIP-98 HTTP auth token creation and verification
• DID:nostr document generation (delegates to solid_pod_rs::did_nostr_types)
• Key management including HKDF derivation from WebAuthn PRF output
• Value types (EventId, Timestamp, Tag, etc.)
