The difference is the newline at the end of the string on each line of
the file. To checksum each line (using the shell and openssl rather than
the much easier Perl with Digest::MD5) but omit the terminating new line:
#! /bin/sh
SAVEIFS="$IFS"
IFS="
"
while read line
do
printf "%s" "$line" | openssl dgst -md5
done < inputfile
IFS="$SAVEIFS"
