My intention was not to question your judgement on your experience,
but only to explain the significance of the strings you mentioned,
with lengths of 63 and 64. That wasn't apparent from your description
of both as "passwords" when only the shorter one is. Being aware of
the difference might help save the time of some future reader of
this thread.

Cheers,
David.
