Summary
Easily and securely send things from one computer to another 🐊 📦
Description
croc
croc is a tool that allows any two computers to simply and securely transfer files and folders. AFAIK, croc is the only CLI file-transfer tool that does all of the following:
- allows any two computers to transfer data (using a relay)
- provides end-to-end encryption (using PAKE)
- enables easy cross-platform transfers (Windows, Linux, Mac)
- allows multiple file transfers
- allows resuming transfers that are interrupted
- local server or port-forwarding not needed
- ipv6-first with ipv4 fallback
- can use proxy, like tor
Usage
To send a file, simply do:
$ croc send [file(s)-or-folder]
Sending 'file-or-folder' (X MB)
Code is: code-phrase
Then to receive the file (or folder) on another computer, you can just do
croc code-phrase
The code phrase is used to establish password-authenticated key agreement (PAKE) which generates a secret key for the sender and recipient to use for end-to-end encryption.
There are a number of configurable options (see --help). A set of options (like custom relay, ports, and code phrase) can be set using --remember.
Custom code phrase
You can send with your own code phrase (must be more than 6 characters).
croc send --code [code-phrase] [file(s)-or-folder]
Allow overwriting without prompt
By default, croc will prompt whether to overwrite a file. You can automatically overwrite files by using the --overwrite flag (recipient only). For example, receive a file to automatically overwrite:
croc --yes --overwrite <code>
Send text
Sometimes you want to send URLs or short text. In addition to piping, you can easily send text with croc:
croc send --text "hello world"
This will automatically tell the receiver to use stdout when they receive the text so it will be displayed.
