Argon2 Hash
Argon2 password hash generation and verification (browser-side simulated implementation).
Configuration
Generate Hash
Verify Hash
Usage
Algorithm Variants
Argon2d: depends on data memory access order, strong resistance to GPU cracking but potentially vulnerable to side-channel attacks. Argon2i: independent of data access order, resistant to side-channel attacks, suitable for password hashing. Argon2id: hybrid mode, uses Argon2i for the first pass and Argon2d for subsequent passes; recommended.
Parameter Description
A higher time cost (iterations) is more secure but slower. Memory cost (KB) affects memory usage; 65536KB (64MB) is recommended. Parallelism controls the number of parallel computation threads. Output length determines the hash size in bytes; 32 bytes is recommended.
Steps
1. Select an algorithm variant (Argon2id recommended) and configure parameters. 2. Enter a password and click "Generate Hash". 3. Copy and save the encoded string. 4. To verify, enter the password and encoded string, then click "Verify".
Notes
This tool uses the browser-side PBKDF2 to simulate the core logic of Argon2; it is not a standard Argon2 implementation. For production use, please use the argon2 library for full security.
