## Issue Addressed

## Additional Info

NIST advice used for PBKDF2 ranges https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-132.pdf. 
Scrypt ranges are based on the maximum value of the `u32` (i.e 4GB of memory)

The minimum range has been set to anything below the default fields.
