Quickly generate and verify Argon2 hashes securely in your own browser (no sensitive information are being sent to our servers), available in all three variants: Argon2d, Argon2i, and Argon2id. Tweak and optimise, in near-real-time, the full set of parametre options available here to make full use out of the algorithm.

You can optimise the the different parametre sets to find out what works the best for you, such as memory (memory cost), iterations (or time cost), and parallelism. Please note that due to the browser constraints, parallelism won't be executed in parallel but will achieve the same desired effects.

Argon2 is a cryptographic hashing algorithm designed for secure password hashing. It was created by Alex Biryukov, Daniel Dinu, and Dmitry Khovratovich and won the Password Hashing Competition (PHC) in 2015. The algorithm was developed to address the need for a more secure, memory-intensive hash function that can resist both brute-force attacks and side-channel attacks, particularly those coming from powerful and modern hardware (i.e. GPUs, ASICs, etc.)

The algorithm has 3 variants:

1. Argon2d – Optimized for resistance to GPU-based attacks by using memory hardness.

2. Argon2i – More resistant to side-channel attacks, like timing attacks, using data-independent memory access.

3. Argon2id – Hybrid of both Argon2d and Argon2i, providing balanced security against both GPU and side-channel attacks.

Let's now talk about some of the benefits of the Argon2 algorithm. It has 3 key advantages, namely, being memory-hard, flexible and configurable across a wide selection of devices, as well as being relatively fast yet secure. Today, it is widely used in modern systems for password storage due to the aforementioned reasons.

Memory-hard: It requires a large amount of memory to compute, making it expensive for attackers to crack with even high-performance hardware.

Flexibility & configurability: Allows fine-tuning of time, memory, and parallelism parametres to adjust the level of security depending on hardware and performance requirements.

Fast & secure: It combines both performance and resistance to various attacks, including brute-force, timing attacks, and trade-off attacks.
