Ha.. that's easy... for shadow, there is either ssha or md5 used. Both
are hashing algorithms, which are not reversable.
This works in this case, as you do:

Make user input a password
Encrypt password
Verify encrpted password with stored encrypted
If they are the same, he very likely gave the wrong plain password.

But in no way can you get from the hash to the password.

For the case with .curlrc (as the OP mentions), the intent is to make
curl use this password without the user typing it, so you need a
reversable encryption. And there you go with the problem.

So, not exactly the same use case.
