---------------------------------------
Summary: Deprecate HashAttribute and CryptographicHashAttribute
Key: NIFI-11184
URL: https://issues.apache.org/jira/browse/NIFI-11184
Project: Apache NiFi
Issue Type: Sub-task
Components: Extensions
Reporter: David Handermann
Assignee: David Handermann
The HashAttribute and CryptographicHashAttribute Processors support different
approaches for digesting one or more FlowFile attribute values using a
configurable algorithm.
The HashAttribute Processor is hard-coded to use the MD5 algorithm, and also
concatenates both the attribute name and value hash.
The CryptographicHashAttribute Processor supports a configurable algorithm, but
computes the hash based on the one attribute value per property configured.
The UpdateAttribute Processor can be configured using Expression Language and
the {{hash}} function to digest one or more attributes as necessary. The
{{hash}} function supports all algorithms available through the
{{MessageDigest}} interface, which should provide sufficient flexibility for
various use cases.
Both the {{HashAttribute}} and {{CryptographicHashAttribute}} Processors should
be deprecated for removal.
