Upgrading from pre-v1.0.0 to v1.0.0

Encryption Upgrade

Please note that starting June 19, 2018, we've switched the encryption scheme for metadata to AES-GCM rather than relying on libsodium. If you have existing data from previous releases, you must first upgrade the encryption scheme. This can be done in the following steps:

  1. Replace environment variable for encryption keys:

    • Existing EWALLET_SECRET_KEY should be renamed to RETIRED_EWALLET_SECRET_KEY.
    • Existing LOCAL_LEDGER_SECRET_KEY should be renamed to RETIRED_LOCAL_LEDGER_SECRET_KEY.

  2. Generate a new key with the following command:

    $ elixir -e "IO.puts 32 |> :crypto.strong_rand_bytes() |> Base.encode64()"

  3. Put the key in environment variables:

    • EWALLET_SECRET_KEY for the new eWallet secret key.
    • LOCAL_LEDGER_SECRET_KEY for the new local ledger secret key.

  4. Run the following command to migrate database and encryption keys:

    $ mix ecto.migrate
$ mix omg.migrate.encryption
