NIP-44 v2 encryption in TypeScript uses ECDH and HKDF to derive a shared conversation key, generating per-message keys for ChaCha20-Poly1305 encryption. This skill provides reference implementations and test vectors to validate cryptographic correctness.

The NIP-59 gift wrap flow is a three-layer process involving a rumor, seal, and gift wrap. It ensures proper signing and routing to protect metadata privacy during Nostr interactions, implemented end-to-end with TypeScript validators and test vectors.

NIP-49 private key encryption uses scrypt and XChaCha20-Poly1305 with password normalization to secure keys. This skill implements the standard in TypeScript, applying cryptographic correctness checks and test vectors for end-to-end validation.

Yes, you can integrate NIP-46 remote signing in TypeScript via kind:24133 events. This skill implements the remote signing architecture and transport, enforcing cryptographic correctness across the full interaction flow with reference material.

NIP-06 key derivation in TypeScript allows hierarchical key generation from a seed. This skill implements the workflow alongside bech32 encoding, providing reference implementations and test vectors to ensure cryptographic correctness.

Yes, the skill includes test vectors, validators, and reference implementations for Nostr cryptography workflows. It enforces cryptographic correctness across NIP-44, NIP-59, NIP-49, and NIP-46 standards in TypeScript modules.
