# These tests use the following parameters generated on a local discourse
|
|
# instance to test an actual authentication flow:
|
|
#
|
|
# - credential_id
|
|
# - public_key
|
|
# - challenge
|
|
# - signature
|
|
# - authenticator_data
|
|
# - client_data_origin
|
|
# - challenge_params_origin
|
|
#
|
|
# To create another test (e.g. for a different COSE algorithm) you need to:
|
|
#
|
|
# 1. Add a security key for a user on a local discourse instance. Go into
|
|
# the console and get the credential_id and public_key params from there.
|
|
# 2. Log out and try to log back in to that user to get the security
|
|
# key challenge
|
|
# 3. Touch the security key. Inside the authenticate_security_key method
|
|
# you need to add puts debugger statements (or use binding.pry) like so:
|
|
#
|
|
# puts client_data
|
|
# puts signature
|
|
# puts auth_data
|
|
#
|
|
# The auth_data will have the challenge param, but you must Base64.decode64 to
|
|
# use it in the let(:challenge) variable. The signature and auth_data params
|
|
# can be used as is.
|
|
#
|
|
# You also need to make sure that client_data_param has the exact same structure
|
|
# and order of keys as auth_data, otherwise even with everything else right the
|
|
# public key verification will fail.
|
|
#
|
|
# The origin params just need to be whatever your localhost URL for Discourse is.
