Unused crypto libraries should not be required (cannot load such file -- bcrypt)

[gregawoods]

I noticed a problem in 3.4.1 that was not present in 3.4.0. My app uses scrypt as the crypto provider. After updating to 3.4.1, my app throws the following error on startup:

[...]/gems/authlogic-3.4.1/lib/authlogic/crypto_providers/bcrypt.rb:1:in `require': cannot load such file -- bcrypt (LoadError)

I believe this related to c2eae1c.

I can add bcrypt to my Gemfile as a workaround. However, in the spirit of keeping my bundle lightweight I would prefer not to have to do this. Can unused libraries be made optional again?

Thanks for your consideration!

I have the same issue

[deefour]

+1 I have

c.crypto_provider = Authlogic::CryptoProviders::Sha512

but am still expected to install bcrypt and scrypt gems now.

I believe there is a fix for this in #406. Can this bug be closed now?

[gregawoods]

@AxisOfEval I would feel more comfortable closing the issue once the linked PR is merged and a release is made to RubyGems.

This is resolved in the latest release. Thanks everyone!
