# EncryptColumn migrates data from an unencrypted column - `foo`, say - to
# an encrypted column - `encrypted_foo`, say.
#
# We only create a subclass here because we want to isolate this migration
# (migrating unencrypted runner registration tokens to encrypted columns)
# from other `EncryptColumns` migration. This class name is going to be
# serialized and stored in Redis and later picked by Sidekiq, so we need to
# create a separate class name in order to isolate these migration tasks.
#
# We can solve this differently, see tech debt issue:
#
# https://gitlab.com/gitlab-org/gitlab-ce/issues/54328
