nostr-nsec-seedphrase/dist/cjs/__mocks__/bech32.js

A comprehensive TypeScript library for Nostr key management with BIP39 seed phrases, supporting both ESM and CommonJS. Implements NIP-01, NIP-06, NIP-19, and NIP-26 with key generation, event signing, bech32 encoding/decoding, and secure cryptographic ope
