    @alopresto Apologies, looks like I had things a bit backward. The template 
given was generating the dynamic content with attributes:
    
    dynamic
    generator_type
    
    and the HashAttributeProcessor was looking for:
    
    dynamic_sha256 -> dynamic
    generator_type_sha256 -> generator_type
    static_sha256 -> static
    
    Changed this to "dynamic -> dynamic_sha256" and files are moving to Success 
and have the correct hashes for ISO-8859-1, US-ASCII, , UTF-8, UTF-16, UTF-16BE 
and UTF-16LE.


> Bring HashContent inline with HashService and rename legacy components

>          Issue Type: Improvement
>          Components: Extensions
>    Affects Versions: 1.7.1
>            Reporter: Andy LoPresto

> As documented in [NIFI-5147|https://issues.apache.org/jira/browse/NIFI-5147] 
> and [PR 2980|https://github.com/apache/nifi/pull/2980], the {{HashAttribute}} 
> processor and {{HashContent}} processor are lacking some features, do not 
> offer consistent algorithms across platforms, etc. 
> I propose the following:
> * Rename {{HashAttribute}} (which does not provide the service of calculating 
> a hash over one or more attributes) to {{HashAttributeLegacy}}
> * Renamed {{CalculateAttributeHash}} to {{HashAttribute}} to make semantic 
> sense
> * Rename {{HashContent}} to {{HashContentLegacy}} for users who need obscure 
> digest algorithms which may or may not have been offered on their platform
> * Implement a processor {{HashContent}} with similar semantics to the 
> existing processor but with consistent algorithm offerings and using the 
> common {{HashService}} offering
> With the new component versioning features provided as part of the flow 
> versioning behavior, silently disrupting existing flows which use these 
> processors is no longer a concern. Rather, Any flow currently using the 
> existing processors will either:
> 1. continue normal operation
> 1. require flow manager interaction and provide documentation about the change
>   1. migration notes and upgrade instructions will be provided
