Construct public/private key pairs and manage user identity securely

Lesson 7

Encode and Decode Identifiers with NIP-19

Transform hex keys into human-readable npub, nsec, and note bech32 formats

Lesson 8

Integrate NIP-07 Browser Extensions

Prompt browser-based signers to authorize actions without exposing raw secret keys
