— Rewrite OFMD5Hash
The old one was based on a public domain implementation, which is
optimized for old compilers and quite unreadable. The new one is written
from scratch and designed to be readable and to exploit optimizations of
modern compilers. (user: js, size: 4615) [annotate] [blame] [check-ins using]

This way, possibly sensitive information is discarded from memory as
soon as possible. (user: js, size: 4654) [annotate] [blame] [check-ins using]
