EN croc: review, download and setup
Send files from a terminal with a one-time code and verify who is receiving them.
What is croc used for?
croc transmits files between computers using the code that the sender reports to the recipient. The main interface works in the terminal. The project describes end-to-end encryption and connection establishment with the possibility of using the repeater.
The transfer code should be considered a secret for the session. Send it to the right person through the trusted channel. A short, user-friendly code is not an occasion to publish it in general correspondence.

Send a test file between two computers
Install the croc on both sides and start with a small file. The sender starts the transfer, and the recipient enters the received code. Before confirming, check the file name and save directory.
After completion, open the result. For important data, compare checksums regardless of the success message. If the transmission suddenly came from an unknown person, do not take and do not start the contents.
Download croc from the official website
Select the supported platform on the project page. The link leads to the selection of the distribution, and does not start the installation automatically.
Use the official download address. Check the signature or checksum if the project publishes one. Keep secret configuration files private when contacting support.

Limitations and data protection in croc
Network restrictions can affect the direct connection and availability of the repeater. Working on one network does not guarantee the same result in another.
Encryption of the channel does not make the resulting file secure. Check the origin and don't run unknown programs.

LocalSend is convenient for graphical transmission on the local network. croc is suitable for terminal exchange between computers; it is better to compare Syncthing for constant synchronization.
Questions and answers
Does the recipient need an account?
The croc script uses the transfer code rather than registration of the croc.
Is the transfer always directly?
Oh, no. The project provides for the establishment of a direct connection and the use of a repeater, depending on the network conditions.
Can I reuse short code for all files?
It is better to use the codes created to transmit and not to distribute them publicly. The code provides access to the relevant session.
