deb-md5sums(5)                  dpkg suite                 deb-md5sums(5)

NAME         top

       deb-md5sums - package MD5 file digests

SYNOPSIS         top

       DEBIAN/md5sums

DESCRIPTION         top

       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).
