Argon2 Hash Generator & Verifier
Generate secure Argon2 hashes and verify passwords against existing hashes. Argon2 is the winner of the Password Hashing Competition and recommended for new applications with configurable memory, time, and parallelism parameters.
Argon2id combines the benefits of both Argon2i and Argon2d and is recommended for most use cases.
Estimated Total Memory: 256 MB
Security Level: Moderate
Recommendation: For password storage, use at least 64MB memory cost with Argon2id.
About Argon2
- • Winner of Password Hashing Competition: Recommended for new applications
- • Memory-hard function: Resistant to GPU and ASIC attacks
- • Three variants: Argon2i (side-channel resistant), Argon2d (faster), Argon2id (hybrid)
- • Configurable parameters: Memory cost, time cost, and parallelism
- • Future-proof: Can adjust parameters as hardware improves
- • Widely adopted: Used by many security-focused applications
- • This tool uses real Argon2 implementation compatible with system tools
Parameter Guidelines
Interactive Applications: 64MB memory, 2-3 iterations, 1-4 threads
Backend Authentication: 256MB memory, 3-4 iterations, 4-8 threads
High Security: 1GB+ memory, 4+ iterations, 8+ threads
Performance Note: Higher parameters provide better security but require more time and memory. Test your configuration to ensure acceptable performance for your use case.
