[SOLVED] ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature Error in rails 5

ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature Error in rails 5

Before migrating to rails 5 it was working nicely, but when I migrated to rails 5.1.1 it is giving me error like

ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature

I have used same key that we were using in the previous version of rails.

Ex.

crypt = ActiveSupport::MessageEncryptor.new(Rails.configuration.secret_key_base)

After executing following line I am getting the mentioned error.

@password = crypt.decrypt_and_verify(User.last.encryptedpass)

Solution

User.last.encryptedpass (User.last.encrypted_password) Are you using devise or our on encryption method?

Raises InvalidSignature if the message was not signed with the same secret or was not Base64-encoded.
