Path to file containing sensitive environment variables.
Some variables that can be considered secrets are:
- WASTEBIN_PASSWORD_SALT:
salt used to hash user passwords used for encrypting pastes.
- WASTEBIN_SIGNING_KEY:
sets the key to sign cookies. If not set, a random key will be
generated which means cookies will become invalid after restarts and
paste creators will not be able to delete their pastes anymore.
