NAME

       deb-md5sums - package MD5 file digests

SYNOPSIS

       DEBIAN/md5sums

DESCRIPTION

       A package declares the MD5 digests for the package file contents by including an md5sums file in its
       control archive (i.e. DEBIAN/md5sums during package creation).  This file is used for integrity
       verification and deduplication purposes, and not for any kind of security purpose.

       This file contains a list of MD5 digests (as 32 case-insensitive hexadecimal characters) followed by two
       spaces (U+0020 SPACE) and the absolute pathname of a plain file, one per line.

       Trailing slashes (U+002F /) in the pathname will be trimmed.  Neither trailing whitespace nor empty or
       whitespace-only lines are accepted.

       If the control file does not exist in the binary package, dpkg(1) will generate the matching information
       at unpack time (since dpkg 1.16.3).
