Webb5 jan. 2024 · For scrypt there are audited, and fuzzed libraries such as noble-hashes. I have created basic scrypt support for Bitwarden. Instead of KDF iterations, there is a “Work Factor” which scales linearly with memory and compute. It has to be a power of 2, and thus I made the user configurable work factor a drop down selection.

The scrypt function is designed to hinder such attempts by raising the resource demands of the algorithm. Specifically, the algorithm is designed to use a large amount of memory compared to other password-based KDFs, [6] making the size and the cost of a hardware implementation much more expensive, and … Visa mer In cryptography, scrypt (pronounced "ess crypt" ) is a password-based key derivation function created by Colin Percival in March 2009, originally for the Tarsnap online backup service.
