The uses of PBKDF2-HMAC-SHA-256 in scrypt are not performance-critical. When scrypt is invoked with sane settings, most of the processing time is spent in scrypt's SMix, not in PBKDF2. This might be the most suitable implementation of scrypt in JavaScript: https://github.com/dchest/scrypt-async-js Its performance test: http://dchest.github.io/scrypt-async-js/demo.html Alexander _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography
