Note: The MD5 digest is more reliable than a simple CRC (provided by
the @command{cksum} command) for detecting accidental file corruption,
as the chances of accidentally having two files with identical MD5
-are vanishingly small. However, it should not be considered truly
-secure against malicious tampering: although finding a file with a
-given MD5 fingerprint, or modifying a file so as to retain its MD5 are
-considered infeasible at the moment, it is known how to produce
-different files with identical MD5 (a ``collision''), something which
-can be a security issue in certain contexts. For more secure hashes,
-consider using SHA-1 or SHA-2. @xref{sha1sum invocation}, and
-@ref{sha2 utilities}.

[DESCRIPTION]

+[BUGS]
+The MD5 algorithm should not be used any more for security related purposes.
+Instead, better use an SHA\-2 algorithm, implemented in the programs
+sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1)
