Software tools edit
ZeroTier markets proprietary tools, which are licensed under a Business Source License 1.1,[7] intended to support the development and deployment of virtual data centers:
In 2021, the product line consists of the following tools:
- ZeroTier One, first released in 2014,[8] is a portable client application that provides connectivity to public or private virtual networks.
- Central, a web-based UI portal for managing virtual networks.
- libzt (SDK), a linkable library that provides the functionality of ZeroTier One but that can be embedded in applications or services.
- LF (pronounced "aleph"), a fully decentralized fully replicated key/value store.
Client edit
The ZeroTier client is used to connect to virtual networks previously created in the ZeroTier Central web-based UI. Endpoint connections are peer-to-peer and end-to-end encrypted. STUN and hole punching are used to establish direct connections between peers behind NAT. Direct connection route discovery is made with the help of a global network of root servers via a mechanism similar to ICE in WebRTC.
Controller edit
Virtual networks are created and managed using a ZeroTier controller. Management is done using an API, proprietary web-based UI (ZeroTier Central), open-source web-based.[9][10] Using root servers other than those hosted by ZeroTier Inc. is impeded by the software's license.
Security edit
The following considerations apply to ZeroTier's use as an SDWAN or VPN application:
- Asymmetric public key encryption is Curve25519, a 256-bit elliptic curve variant.
- All traffic is encrypted end to end on OSI layer 1 using 256-bit Salsa20 and authenticated using the Poly1305 message authentication (MAC) algorithm.[11] MAC is computed after encryption (encrypt-then-MAC) and the cipher/MAC composition used is identical to the NaCl reference implementation.[12]
