How do I find my IPhone encrypion pass word?

You don't.

You either know it or you don't.

If you don't, you have to reset your password which wipes the phone and as that generates a new encryption key so even if you could get a hex dump of the old date it would be undecipherable nonsense.

Afterwards you use iTunes on your host computer to restore the wiped data to your phone. No iTunes/iCloud backup? Tough: the data is lost.
