Answer 1

What if you tried reinstalling the bcrypt-ruby gem?

  # Remove all versions of bcrypt-ruby
  sudo gem uninstall bcrypt-ruby

  # Install the latest version 
  sudo gem install bcrypt-ruby

Answer 2

Reinstalling bcrypt-ruby hasn't worked for me.

The bug got fixed in bcrypt-ruby >= 3.1.10, but Rails 3.2 locked on bcrypt-ruby 3.0.x.

Solution would be to either:

• move to newer Rails version (>=4)
• use older Ruby version (2.1.x)
• fork my changes and keep up with security updates by yourself (since currently Rails 3.2 supports only severe security updates)
