📋 When to Use 64-Character Passwords
64 characters is cryptographic-grade. This is the length used for SSL/TLS private keys, encryption salts, and quantum-resistant algorithms. For 99.9% of users, this is unnecessary. But if you're building a CA, generating a master encryption key, or preparing for post-quantum cryptography — this is the right tool.
📊 Technical Breakdown — 64-character
- Entropy: 365 bits (full)
- Crack time: 2^365 combos
