Argon2 Online Encryption/Verification

This tool generates and verifies Argon2 password hashes with configurable algorithm variant and core cost parameters.

Key Features

• Generate and verify modes
• Tunable memory, iterations, parallelism, and hash length
• Supports Argon2id, Argon2i, and Argon2d
• Copy-ready output with timing display

Steps

1. Enter password and set parameters in Generate mode.
2. Select Argon2 variant and generate hash.
3. Verify with password and hash in Verify mode.

Use Cases

• Password storage strategy evaluation
• Security/performance parameter tuning
• Hash migration validation

Notes

• Prefer Argon2id for most modern deployments.
• Stronger settings increase compute and memory cost.
• In production, combine with rate limiting, MFA, and auditing.
