Description

RFC 1321 was published in 1992 and described the MD5 message-digest algorithm. Multiple researchers have found security issues in the MD5 algorithm. The Federal Information Processing Standard 140-2 does not allow MD5 to be used.

Several NiFi framework classes use the MD5 algorithm for determining whether file contents have changed. Although these uses do not relate directly to encryption operations, use of the MD5 algorithm should be replaced with a modern algorithm that is not subject to the same security issues.
