Lease a port to see your command line.
Communication between B4CK.net clients deployed in your internal network and our servers is always encrypted with TLS 1.3. Select the "TLS" radio button when requesting a new lease to also encrypt communication with the port leased on our B4CK.net servers. This requires connecting the service with a TLS-enabled client.
End-to-end encryption must, by definition, be performed between machines you control, and not on our servers. We recommend chaining the B4CK.net service with stunnel for end-to-end encryption.
Private servers are registered in custom subdomains of the b4ck.net domain. Alternatively, customers may use their own domains with our servers. TLS encryption for such domains needs to be configured on customers' internal servers, which also ensures end-to-end encryption.
The B4CK.net service may not be used to perform any illegal activities.
