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).
