nostr-crypto-guide

The skill presents a coherent, purpose-aligned cryptography guide for Nostr-related primitives. There are no executable install steps, no credential harvesting, and no external network endpoints specified. The documented patterns are appropriate for a developer-focused reference. Because the content is a specification/guidance document rather than a runnable tool, it poses low operational risk. Treat as benign to potentially high if misimplemented; ensure proper validation, secure key handling, and adherence to the specified NIPs in any implementation.
