krypto

krypto is the cryptography toolbox. Includes:

• Password hashing with bcrypt and argon2id
• AES-GCM symmetric encryption
• JWT signing and verification (RS256 and HS256)
• HMAC helpers
• RSA key generation
• OTP (TOTP/HOTP)
• Secure random generation

All defaults are chosen to satisfy the security baseline in the GoBeaver project guidelines (Argon2id or bcrypt cost ≥ 12, AES-256-GCM, etc.).
