📖 Description

In the field of cryptography, Scrypt is considered stronger than PBKDF2 and earlier Bcrypt:

Memory Dependency: Traditional algorithms like MD5 or SHA require minimal memory to run, allowing attackers to use cheap hardware for parallel attempts. Scrypt mandates significant memory usage, drastically reducing an attacker's parallel efficiency.
Resistance to Hardware Acceleration: ASIC chips designed specifically for cracking lose their cost advantage against Scrypt, as they require expensive, high-speed memory in large quantities.
High Tunability: Developers can freely adjust the CPU/memory cost factor (N), block size (r), and parallelization factor (p), allowing security strength to be continuously upgraded alongside hardware advancements.
Wide Adoption: Scrypt is the core algorithm for Litecoin and the preferred choice for many modern file encryption tools and cloud services for password storage.

This site's tool provides complete parameter configuration to help you achieve precise algorithm matching:

N (Cost Factor / CPU/Memory Cost): Iteration count, must be a power of 2. A higher value makes computation slower and consumes more memory.
r (Block Size): Block size, adjusts the amount of memory for sequential reads. A common value is 8.
p (Parallelization Factor): Parallelization factor, controls the number of threads for parallel computation.
Salt: A unique random string generated for each user to prevent rainbow table attacks.
Key Length: The byte length of the derived key (typically 32 or 64 bytes).

Input the original password and set custom parameters.
Based on Scrypt algorithm logic, the system generates a highly crack-resistant hexadecimal digest through complex sequential memory transformations.

If you already have a Scrypt hash stored in a database, you can compare it with a user's input plaintext password.
The tool will recalculate using the same Salt and parameters and report the match result.

Core Security: All complex memory operations are performed entirely in your browser frontend (Client-side).
Data Isolation: Your plaintext password and derived result are never uploaded to the server. Even when handling the highest-level root passwords, using this site is equivalent to operating on your local terminal.

Scenario	Recommended Parameters (N, r, p)	Security Level
