Did something in the hashes change from 6 to 8?

Mellow greetings!
On a box running FreeBSD 6.something (probably 6.4) the boot drive died.
I had never bothered to update it to 7 or 8, since I was planning to
build a new computer anyway. Since I hadn't done that yet and I still
needed the work of this machine, I just put in a new drive and installed
8.0.
The deal is that a script I restored from backup doesn't quite work as I
think it should. This is the part that somehow causes problems:
!/bin/sh
stty -echo
read -p "Enter passphrase: " passphrase
stty echo
main=`echo "${passphrase}" | sha256 | cut -c 1-5`
if [ "${main}" != "ddfab" ]; then
echo "Wrong passphrase!"
exit
fi
I have typed the password in question about a gazillion times, so I am
pretty sure I got it right. But somehow the 'if' keeps kicking in.
There are two possible reasons for this:
1. I have Alzheimer's.
2. Something about the way sha256(1) and/or digest(1) or one of the
other commands in the script react differenly than before.
Maybe there is another reason that I just don't see?
Can someone help me out here?
Regards,
Chris
