md5 wrongness?

[Ron Johnson]

Why do Python's md5 and GNU md5sum produce differing results?

$ md5sum --version
md5sum (GNU coreutils) 5.97

$ echo snagglefrob | md5sum
f842244d79af85b457811091319d85ff -
$ echo 'snagglefrob' | md5sum
f842244d79af85b457811091319d85ff -
$ echo "snagglefrob" | md5sum
f842244d79af85b457811091319d85ff -

echo inserts a newline, your Python snippet doesn't.

% echo -n "snagglefrob" | md5sum

They don't differ. Try feeding them the same input:

$ md5sum --version
md5sum (GNU coreutils) 5.97

$ echo snagglefrob | md5sum
f842244d79af85b457811091319d85ff -
$ echo 'snagglefrob' | md5sum
f842244d79af85b457811091319d85ff -
$ echo "snagglefrob" | md5sum
f842244d79af85b457811091319d85ff -

They don't differ. Try feeding them the same input:

Or, alternatively:

$ echo -n snagglefrob | md5sum

Thanks to all. I knew there had to be operator error, but I
couldn't figure out where...
