What is Croc?

croc is a tool that enables users to easily and securely transfer data between computers. It provides a secure peer-to-peer transfer mechanism, allowing users to transmit encrypted data using a simple code phrase. The tool utilizes a combination of three random words, known as a mnemonic code, to facilitate a password-authenticated key exchange (PAKE) process. This cryptographic method generates a strong encryption key from the shared, yet weak, code phrase. Importantly, each code phrase can only be used once between the sender and recipient, ensuring a less than one-in-four-billion chance of an attacker guessing the code correctly and intercepting the data. If an attacker attempts to use an incorrect code phrase, the transfer will fail, and the sender will be notified, without any data being exchanged. This secure architecture allows only the intended parties, those with the correct code phrase, to successfully transfer encrypted data through a relay

Highlights

• Secure peer-to-peer data transfer between computers
• Utilizes password-authenticated key exchange (PAKE) for end-to-end encryption
• Each code phrase can only be used once, reducing the risk of data theft
• Ability to resume broken transfers
• Cross-platform compatibility for easy installation and use
