how to manually check the MD5 of a file in SVN

I get a Base checksum mismatch error on commit operation. Not sure what
could have changed (or not changed) the hashed file or what could have
altered the MD5 during transportation (check out time or check in time).
While checking out, the working copy did not receive the original checksum
but an altered one; Working copy is not in sync. While checking in, the
server did not receive the original checksum or file but an altered one;
Does anyone knows how too manually check the MD5 of a file in SVN ? So that
i can make sure than after a checkout and before a checkin MD5 are
identical in the working copy and the server.
