deb-md5sums(5) dpkg suite deb-md5sums(5)
deb-md5sums - package MD5 file digests
DEBIAN/md5sums
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).
