-### Using `croc` on Linux or Mac OS
-
-On Linux and Mac OS, the sending & receiving is slightly different to avoid [leaking the secret via the process name](https://nvd.nist.gov/vuln/detail/CVE-2023-43621). On these systems you will need to run `croc` with the secret as an environment variable. For example, to receive with the secret `***`:
-
-```
-CROC_SECRET=*** croc
-```
-
-This will show only `croc` in the process list of a multi-user system and not leak the secret.
-
-For a single-user system the default behavior can be permanently enabled by running
-
-```
-croc --classic

-You can choose from several different hash algorithms. The default is the `xxhash` algorithm which is fast and thorough. If you want to optimize for speed you can use the `imohash` algorithm which is even faster, but since it samples files (versus reading the whole file) it can mistakenly determine that a file is the same on the two computers transferring - though this is only a problem if you are syncing files versus sending a new file to a computer.
