While liability is the usual reason for most otherwise inexplicable organizational actions, I don't think it's a concern for the federal government.

I think it was the case that the entropy spreadsheet required user support that NIST wasn't prepared to give, and the contract with the organization that produced it had expired.

Hi Mark,

NIST used to have a password entropy tool on their website, but it was taken
down a couple of years back. I downloaded it prior to its demise and have
attached it, in case this might help.

Folks:

I use to have a spreadsheet tool that allowed me to
model the entropy strength for a credential by adjusting
different parameters (#char, size of character set, TTL,
lockout rule, etc.). I appear to have lost track of
it and was wondering if the collective could suggest/share/point
me to a replacement resource? I thought I would ask
before trying to reconstruct from first principles.

Thanks in advance,
Mark
