Devise Encryptor, why authlogic_sha512?

[aaronzdavis]

I was surprised to see the default encryptor for Devise was overwritten in this gem. Is there a good reason for this?

When I attempted to export my solidus user database to another platform, Firebase Auth, I couldn't find a solution for importing the passwords using the SHA512 examples found in their docs: https://firebase.google.com/docs/auth/admin/import-users

Perhaps someone here might have a clue how to get passwords over to Firebase Auth.

Here's where the encryptor is being set in this repo.

solidus_auth_devise/config/initializers/devise.rb

Line 43 in ed42532

config.encryptor = 'authlogic_sha512'

I encountered this recently. We should probably maintain that setting for old apps, but use bcrypt for new installations. I dug into it and the decision to use authlogic_sha512 goes back really far and I couldn't find any explanation in the git history/project for it.

Historically the idea was probably stolen from devise:
Devise Encryptors

@jarednorman Can this be changed to something more migration friendly?
