Scrypt

Also known as Scrypt key derivation function

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. The algorithm was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory. In 2016, the scrypt algorithm was published by IETF as RFC 7914. A simplified version of scrypt is used as a proof-of-work scheme by a number of cryptocurrencies, first implemented by an anonymous programmer called ArtForz in Tenebrix and followed by Fairbrix and Litecoin

scrypt（唸作「ess crypt」），是加拿大計算機科學家暨計算機安全研究人員（Colin Percival）於2009年所發明的密钥派生函数，當初設計用在他所創立的服務上。設計時考慮到大規模的而刻意設計需要大量記憶體運算。2016年，scrypt演算法發佈在RFC 。scrypt的簡化版被用在數個密碼貨幣的工作量證明（Proof-of-Work）上。
