nostr-nsec-seedphrase/dist/__mocks__/bip39.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
