scrypt FAQ
What is scrypt?
scrypt is a memory-hard key derivation function designed by Colin Percival in 2009. It was originally created for the Tarsnap backup service and is also used in Litecoin mining.
What parameters should I use?
OWASP recommends: N = 2^17 (131072), r = 8, p = 1 for interactive logins. Memory usage ≈ 128 × N × r bytes. With default params, this uses ~128 MB.
scrypt vs Argon2id?
Argon2id is generally preferred for new applications as it won the Password Hashing Competition and offers more tunable parameters. scrypt is still secure but has a less flexible security/performance tradeoff.
What does each parameter do?
N (CPU/memory cost) must be a power of 2 and dominates memory usage. r (block size) controls memory read patterns. p (parallelism) allows computing multiple hashes in parallel.
