Storage Credentials Security

When you attach an external storage, Arcsecond.local needs its credentials to read from it. Here is how those credentials are kept safe:

• Credentials leave the browser already encrypted, and reach the Arcsecond.local backend over HTTPS.
• They are stored in an encrypted field in the database. The field encryption key (FIELD_ENCRYPTION_KEY) lives in your install's .env file, outside the database itself — so a database dump alone never exposes them.
• No URL route exposes these credentials, and they never appear in any other Arcsecond resource, even to authenticated users, even to the storage owner.
• No credentials of any kind appear in the (private or public) source code.
• The database is backed up hourly (see Backups); keep those dumps and your .env on separately-permissioned storage, since together they would unseal the encrypted fields.

Because Arcsecond.local runs on your own infrastructure, these credentials never leave your machines.
