About this Tool
Use this scrypt generator to test password hashing and key derivation parameters. Because scrypt is intentionally resource-intensive, parameter limits should protect the browser from excessive memory use.
Examples
- Generate a scrypt hash
- Derive a 256-bit scrypt key
- Test custom N, r and p values
Frequently Asked Questions
What makes scrypt different?
Scrypt is designed to require significant memory as well as processing time, making large-scale password guessing more expensive.
What do N, r and p mean?
N controls the main work factor, r controls block size and p controls parallelization.
Can high settings freeze the browser?
Yes. Extremely high memory or work parameters can make the browser slow or unresponsive, so the tool should enforce safe limits.
