I am using Cloak 0.6.2 version. It was working all good. I upgraded the Elixir version to Elixir 1.13.0, Phoenix - 1.5.9 and phoenix_pubsub : 2.0.
After upgrading, I am getting the following error
(exit) an exception was raised:
** (UndefinedFunctionError) function Cloak.EncryptedBinaryField.equal?/2 is undefined or private
(cloak 0.6.2) Cloak.EncryptedBinaryField.equal?(nil, “Basement Flat, 2 Barons Court Road”)
(ecto 3.7.2) lib/ecto/changeset.ex:576: Ecto.Changeset.cast_field/8
Thanks for the reply. I can update the version, but should we have to migrate the old existing encrypted data as well? Will it have a huge impact? Bit concerned about the Production data.
I have upgraded to cloak_ecto, it is failing to load the previous data.
** (ArgumentError) cannot load <<65, 69, 83, 1, 225, 62, 249, 49, 101, 202, 45, 28, 221, 3, 238, 254, 112, 32, 115, 255, 128, 10, 119, 251, 104, 191, 116, 53, 199, 229, 23, 108, 129, 178>> as type MyApp.Encrypted.Binary for field :phone_number in %MyApp.Profile{meta: #Ecto.Schema.Metadata<:loaded, “profiles”>,
Data migration is also not possible.
y_future_now, MyFutureNow.Vault,
ciphers: [
default: {
Cloak.AES.CTR,
tag: "AES",
key: Base.decode64!(cloak_key_1),
# In AES.GCM, it is important to specify 12-byte IV length for
# interoperability with other encryption software. See this GitHub
# issue for more details:
# https://github.com/danielberkompas/cloak/issues/93
#
# In Cloak 2.0, this will be the default iv length for AES.GCM.
iv_length: 12
# }
# ]
I will try with key: :base64.decode(cloak_key_1) for now in upgraded
Sorry for giving you a confusing advice. Since you’re updating from a pretty old version of Cloak, I think you should follow the upgrade guide and perform each minor version upgrade step by step, that is upgrade 0.6 to 0.7, 0.7 to. 0.8, etc. until you migrate to the latest one.
Like @stefanchrobot suggests, you’ll need to upgrade cloak incrementally to catch up. You’ll also need to do this before changing your Ecto etc version, as vintage cloaks are not compatible with current Ecto.
@stefanchrobot@al2o3cr I did the same thing of incrementing it step by step.
It did not work then as well.
However there was a data migration when we upgrade it from 0.6 to 0.7, which I did not perform.
As I did not have much time, I would look into this later.
