Altho it's not md5, you can use cmp utility to compare 2 files and test return.

If files are different it will return 1, otherwise it will be 0
Code:
root@glitch:/myfiles# cat file*
1
2
1
root@glitch:/myfiles# cmp file1 file2
file1 file2 differ: byte 1, line 1
root@glitch:/myfiles# echo $?
1
root@glitch:/myfiles# cmp file1 file3
root@glitch:/myfiles# echo $?
0

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xzdiff  invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All options specified
       are passed directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a
       supported  compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they
       are uncompressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
