How to decrypt base64 SAML response ?

[anantaUM]

Hello Everyone,

I used this gem in our application to setup Shibboleth based authentication. The SAML response received from Identity provider is base64 encoded.

I have following setup in attribute-map.yml,

"urn:mace:dir:attribute-def:mail" : "email"

After successful login, I see that it is storing encoded value in the email column of users table. What do I need to do to decrypt the base64 encoded SAML response ?

Please advice.

Thank you for your time.

@anantaUM check out the saml_update_resource_hook configuration:

devise_saml_authenticatable/lib/devise_saml_authenticatable.rb

Lines 117 to 121 in 37d457b

	# Proc that is called if Devise.saml_update_user and/or Devise.saml_create_user are true.
	# Receives the user object, saml_response and auth_value, and defines how the object's values are
	# updated with regards to the SAML response. See saml_default_update_resource_hook for an example.
	mattr_accessor :saml_update_resource_hook
	@@saml_update_resource_hook = @@saml_default_update_resource_hook

. You can override that to add custom behavior when updating user attributes.
