**What features would the enhancement add?**
1\. document a invalid hash value
2\. test / make sure that it does not validate
**What parts of the project would this effect?**
1\. documentation
2\. tests
**Please provide any additional information below\.**
For some purposes \(like password "reset"\), one needs a specific hash value that never ever validates against any given password\.
Currently, I use "" \(empty string\), but IIRC it is not really documented that this is a hash that is assured to never validate\.
