Function dupPassword
This function exists as a convenience in case you need it, HOWEVER it's
recommended to design your code so you DON'T need to use this (use
toPassword instead):
Using this to create a Password cannot protect the in-memory data of your
original string because a string's data is immutable (this function must
.dup the memory).
While immutability usually improves safety, you should avoid ever storing unhashed passwords in immutables because they cannot be reliably zero-ed out.
