Ballot Text

Technical Summary: 

   This document specifies the password-based key derivation function scrypt.  
   The function derives one or more secret keys from a secret string.  It is 
   based on memory-hard functions which offer added protection against attacks 
   using custom hardware.

Working Group Summary: 

   This was an individual effort to document an external algorithm. It 
   was presented at the CFRG in IETF-92; there is no controversy.

Document Quality: 

   It is a good, well-written document; it includes test vectors.  An
   interoperable implementation was written for OpenSSL based on 
   this document.

Personnel: 
 
    Stephen Farrell is AD; Rich Salz is the shepherd
