comment Do `sudo` and `su` belong to capability-based security?
Both sudo and su can be used to run any command as any user, the main difference between them is that sudo alows for fine grain permissions for commands and does not force the user to know the password of the user they're impersonating to (it can be configured to, though). The requirement for the calling user password is just the default configuration, and can be turned off.

comment Do `sudo` and `su` belong to capability-based security?
Yes, since they do not share capabilities, and is very far from the principle of least privilege since most uses of the sudo and su programs is used to run a program as root without it aware that it was run by sudo.

@StephenTouset you have asked an excellent question. I think it'll be better to post it as a question so people can find it. (you are welcome to comment with a link)

Knowing if it's consistent across multiple tries is half the question, I did not know if there's some command line option to set the random component to a fixed preset one. Running the same command twice will tel me how it is in my version, I didn't know in advance if there are different behaviours for different versions.

I didn't mention it before, but I guessed it would have a random component, now I need to save the md5sum of the encrypted version.
