2012: current uses of scrypt As KDF in scrypt author's simple file encryption program As KDF in Tarsnap, scrypt author's "online backups for the truly paranoid" As a proof-of-work scheme in Litecoin, "a coin that is silver to Bitcoin's gold" (after Bitcoin mining became feasible on GPUs and FPGAs only... ASIC, anyone?) No crypt(3) encoding syntax is defined for scrypt yet scrypt author is the FreeBSD Security Officer. He must be really good at resisting the temptation of making the system use his new creation (creature?) before it's "mature"
