md5sum mistery

Itching Armpit · External Since: Oct 15, 2009 Posts: 2

me@here:~# md5sum
burp [RETURN, CTRL+D]
38d153ba17c6222412f4fae9c50ff32b -

Online services give a different md5 for "burp":
http://gdataonline.com/makehash.php

Word Hash
burp afaff8193505e29230b76f8c8dd78170

Why is md5sum in disagreement?

you@there:~$ echo burp | md5sum
38d153ba17c6222412f4fae9c50ff32b -

afaff8193505e29230b76f8c8dd78170 -

It isn't:

$ echo -n burp | md5sum
afaff8193505e29230b76f8c8dd78170 *-

As you hit "RETURN" before "CTRL+D", you sent a "\n" (newline) character
after your "burp" and so it was added to the characters to build the
checksum from.

Explains why I got differing md5sums on the command line and in php then?
