Rpm uses whatever digest it was configured to use when building packages. RHEL-6 content has SHA256 file digests, older packages have MD5 and 3rd party packages could (although there's not much point in doing so) use something different still. So it's not a case of s/MD5/SHA256/, more like s/MD5/digest/ but it's not that straightforward either as there are places where MD5 is still used, such as the pkgid. In other words, it's not a straightforward 'perl -pi -e "s/MD5/SHA256/"' job and dunno if it's really worth the trouble for rhel-6 at this point, there are probably more important issues to address. Obviously the terminology should be fixed at least upstream sooner or later. 'perl -pi -e "s/MD5/SHA256/"' is not what I ment. Actually, I think that mentioning that other digest than MD5 are possible would be fine. This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux release for currently deployed products. This request is not yet committed for inclusion in a release. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: rpm-4.8.0-19.el6 rpm manpage is refering to MD5 digests in many places, it is also part of the name of some options. It should be mentioned that rpm is actually using SHA256 hashes. --fileid MD5 Query package that contains a given file identifier, i.e. the MD5 digest of the file contents. --pkgid MD5 Query package that contains a given package identifier, i.e. the MD5 digest of the combined header and payload contents. Verifying a package compares information about the installed files in the package with information about the files taken from the package metadata stored in the rpm database. Among other things, verifying compares the size, MD5 sum, permissions, type, owner and group of each file. Any discrepancies are displayed. Files that were not installed from the package, for example, documentation files excluded on installation using the "--excludedocs" option, will be silently ignored. S file Size differs M Mode differs (includes permissions and file type) 5 MD5 sum differs D Device major/minor number mismatch L readLink(2) path mismatch U User ownership differs G Group ownership differs T mTime differs P caPabilities differ
