> Replace Framework Uses of MD5 with Modern Algorithm
> ---------------------------------------------------
>
> Key: NIFI-8132
> URL: https://issues.apache.org/jira/browse/NIFI-8132
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.12.1
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Major
> Labels: FIPS, MD5, security
> Time Spent: 4h 20m
> Remaining Estimate: 0h
>
> [RFC 1321|https://tools.ietf.org/html/rfc1321] was published in 1992 and
> described the MD5 message-digest algorithm. Multiple researchers have found
> [security issues|https://en.wikipedia.org/wiki/MD5#Security] 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.
