Smart Password Generator CLI (C#) ^v4.0.0

Terminal-based smart password generator with deterministic password generation

Generate passwords from secret phrases — same secret always produces the same password, no storage required.

C# .NET CLI Password Generator Cross-Platform Zero-Storage

GitHub

Smart Password Generator CLI (C#) — terminal-based smart password generator with deterministic password generation. Generate passwords from secret phrases — same secret always produces the same password, no storage required. All from your command line.

Decentralized by Design: Unlike traditional password managers that store encrypted vaults on central servers, Smart Password Generator stores nothing. Your secrets never leave your device. Passwords are generated on-demand — no cloud, no database, no trust required.

Cross-Platform: Windows, Linux support.

⚠️ Breaking Change (v4.0.0)

This release uses smartpasslib-csharp v4.0.0, which is NOT backward compatible with v1.0.3. Smart passwords created with older versions cannot be regenerated with v4.0.0.

📖 Full migration instructions → see MIGRATION.md

Zero-Storage Security — no passwords or secret phrases are ever stored or transmitted
Decentralized Architecture — no central servers, no cloud dependency
Deterministic Generation — same secret + same length = same password, every time
Memory-Based Security — your brain is the only password database
Cross-Platform — Windows, Linux support
Multi-Mode Generation — smart passwords, strong random, auth codes, public keys, verification

Decentralized & Serverless — no central database, no cloud lock-in
Smart Password Generation — deterministic from secret phrase
Dynamic Iteration Counts — 15-30 for private key, 45-60 for public key
Public Key Generation — generate verification key from secret
Secret Verification — verify secret against public key
Strong Random Passwords — cryptographically secure random passwords
Authentication Codes — short codes for 2FA/MFA (4-100 chars)
Interactive Mode — menu-driven interface for easy use
Command-Line Mode — scriptable generation for automation
Hidden Input — secret phrase entry with asterisks masking

Key derivation (same as Python/JS/Kotlin/Go versions v4.0.0):

Key Type	Iterations	Purpose
Private Key	15-30 (dynamic)	Password generation (never stored, never transmitted)
Public Key	45-60 (dynamic)	Verification (stored locally)

Character Set (Google-compatible):

!@#$%^&*()_+-=[]{};:,.<>?/ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz

Validation Rules: Secret phrase: min 12 chars · Password length: 12-100 chars · Code: 4-100 chars

Command	Description
`smart <secret> <length>`	Generate deterministic password (12-100 chars)
`strong <length>`	Generate cryptographically random (12-100 chars)
`code <length>`	Generate auth code (4-100 chars)
`public <secret>`	Generate public key from secret
`verify <secret> <public_key>`	Verify secret against public key
`help`	Show help information

Security Model:

Proof of Knowledge — public keys verify secrets without exposing them
Decentralized Trust — no third party needed
Deterministic Certainty — mathematical certainty in password regeneration
Ephemeral Passwords — passwords exist only in memory during generation
Local Computation — no data leaves your device
No Recovery Backdoors — lost secret = permanently lost passwords

Secret Phrase Requirements:

Minimum 12 characters (enforced)
Case-sensitive
Use mix of: uppercase, lowercase, numbers, symbols
Never store digitally
NEVER use your password description as secret phrase

Strong Secret Examples:

✅ "MyStrongSecretPhrase2026!"   — mixed case + numbers + symbols
✅ "P@ssw0rd!LongSecret"         — special chars + numbers + length
✅ "КотБегемот2026НаДиете"       — Cyrillic + numbers

Weak Secret Examples (avoid):

❌ "short"                       — too short, rejected
❌ "password"                    — dictionary word, too short
❌ "1234567890"                  — only digits, too short
❌ "qwerty123"                   — keyboard pattern
