> Add ability to hash an attribute or value in expression language
> ----------------------------------------------------------------
>
> Key: NIFI-6287
> URL: https://issues.apache.org/jira/browse/NIFI-6287
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Ed Jackson
> Assignee: Phillip Grenier
> Priority: Trivial
> Labels: expression-language
>
> Similar to 6255
>
> In expression language it would be very useful to hash arbitrary data or
> attributes from the incoming flow file. For example, if the incoming flow
> file has an attribute called 'serial_num', the user can hash this value in
> expression language like `${hash('MD5', 'serial_num')}` or similar syntax.
>
> Today users need to add a CryptographicHashAttribute processor to accomplish
> this.
