[NAME]
md5sum \- compute and check MD5 message digest
[DESCRIPTION]
.\" Add any additional description here
[BUGS]
Do not use the MD5 algorithm for security related purposes.
Instead, use an SHA\-2 algorithm, implemented in the programs
sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1),
or the BLAKE2 algorithm, implemented in b2sum(1)

doc: improve the info on md5sum security weaknesses * doc/coreutils.texi (md5sum invocation): Mention currently known security problems. Don't recommend SHA-1 as alternative. * man/md5sum.x (BUGS): Warn about the vulnerabilities and reference the SHA-2 based alternatives. Reported by Simon Josefsson 2010-08-10 01:56:36 +01:00			`[BUGS]`
doc: give a stronger security warning in md5/sha1 man pages * man/md5sum.x: Give a more direct warning againt the use of this hash algorithm for security purposes. * man/sha1sum.x: Likewise. Suggested by Jim Meyering. 2017-03-01 09:33:29 -08:00			`Do not use the MD5 algorithm for security related purposes.`
			`Instead, use an SHA\-2 algorithm, implemented in the programs`
doc: indicate sha1 has the same limitations as md5 * doc/coreutils.texi (sha1sum invocation): Given that a SHA-1 preimage attack has occurred as documented at http://shattered.io/, document sha1sum as having the same limitations as md5sum. (md5sum): Parameterize the warning for use in both cases. * man/md5sum.x: Mention b2sum(1) as a more secure alternative. * man/sha1sum.x: Give the same warning as done for md5sum(1). 2017-02-28 20:14:58 -08:00			`sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1),`
			`or the BLAKE2 algorithm, implemented in b2sum(1)`
cksum: add --algorithm option to select digest mode * src/digest.c: Organize HASH_ALGO_CKSUM to be table driven, and amalgamate all digest algorithms. (main): Parse all options if HASH_ALGO_CKSUM, and disallow --tag, --zero, and --check with the traditional bsd, sysv, and crc checksums for now. * src/local.mk: Reorganize to include all digest modules in cksum. * tests/misc/cksum-a.sh: Add a new test. * tests/misc/b2sum.sh: Update to default to checking with cksum, as b2sum's implementation diverges a bit from the others. * tests/local.mk: Reference the new test. * doc/coreutils.texi (cksum invocation): Adjust the summary to identify the new mode, and document the new --algorithm option. * man/cksum.x: Adjust description to be more general. * man/sum.x: Add [See Also] section referencing cksum(1). NEWS: Mention the new feature. 2021-09-06 15:17:12 +01:00			`[SEE ALSO]`
