What gets encrypted
CursorHop's encryption covers every type of data that passes between your computers. This includes raw mouse movement coordinates, click events, scroll inputs, every keystroke (including passwords and sensitive text), clipboard contents (text and images), and complete file transfer payloads. Nothing leaves your machine unencrypted.
The encryption happens at the application layer before the data is handed to the network stack. This means even if someone captures your network packets, they see only encrypted ciphertext.
Noise protocol encryption
CursorHop uses the Noise protocol framework, the same cryptographic foundation used by Signal, WireGuard, and WhatsApp. Noise provides modern authenticated encryption with forward secrecy, designed for simplicity, security, and performance. It is widely audited and trusted for protecting real-time communications.
Why encryption matters for input sharing
When you share a mouse and keyboard between computers, every action you take is transmitted over the network. Without encryption, anyone on the same network could capture these transmissions and reconstruct exactly what you typed — including passwords, private messages, and confidential documents. On a shared office, co-working space, or university network, this is a real risk.
Automatic key exchange
You never have to manage encryption keys manually. When two CursorHop instances connect, they perform an automatic key exchange using the Noise handshake to establish a shared secret. The process is transparent — you simply connect your computers and encryption is active.
Zero-configuration security
There are no settings to toggle, no certificates to install, and no passphrases to remember. If you are on a Pro or Max plan, encryption is always on. This design choice eliminates the risk of accidentally running without encryption because you forgot to enable a setting.
Contrast with unencrypted alternatives
Many legacy input-sharing tools transmit keystrokes and mouse data in plaintext. This means anyone with a packet sniffer on the same network can see everything you type. CursorHop was designed from the ground up with encryption as a core feature, not a bolt-on afterthought.
Encryption availability
Noise encryption is available on all plans, including the free trial. All data transmitted between your devices is encrypted automatically. The free trial includes full Pro features with encryption for up to 2 computers. Pro Plus supports 5 computers and Max supports up to 10.
