I would like to find a delimiter value that I can use to both create and
read from a flat-file database where splitting on the $delimiter doesn't
improperly split either the encryptedpassword value, or a reasonable
date format.

Question:

What would a good value for $delimiter be?

The only way to guarantee that your delimiter won't be part of the data
is to make it longer than any possible field. That way, it would be
impossible for your encryption algorithm to accidentally create it.
