Forgive me one other question; since blowfish output uses non-printable characters (including nul, I do believe), I assume you're converting them to printable (for easy storage and use in flat files or databases)? If so, how do you think this will impact the number of collisions? -----Original Message----- From: James Davis [mailto:james.davis@st-peters.oxford.ac.uk] Sent: Wednesday, August 14, 2002 6:25 PM To: forensicsat_private Subject: blowfish cryptographic hash function Hello, For the past few days I've been writing a program in the style of md5sum but that uses the blowfish algorithm to create a cryptographic hash function. I've been lurking in this group for a little while and thought it may be of some interest here. I'd be interested in what people think of my work so far, it compiles without problem as far as I know under Cygwin, Linux and OpenBSD. It's available at http://users.ox.ac.uk/~spet1067/bfsum/ and is far from polished at the moment. It's slow (although I have improved this), lacks the -c option of md5sum, ignores the binary/text options and the code is quite messy. For those who try it, I apologise for filename that results from compilation but I've been using the same Makefile in windows.
