It sends the password, if you have your Apple Keychain synced in iCloud, you can then go on your Mac and access the password in the list of saved wifi password.

  You can't, because it's hashed. Check it right now, all the shared passwords are just hashes.

    Sorry but this is incorrect - they can't be hashed because the password needs to be used as-is for the wireless authentication procedure, at least for PSK-based auth (EAP can indeed use certificates and the private key is never revealed). The key is probably stored in some hex format (I think wpa_supplicant in Linux also supports this format) but it's not hashing per-se as it's reversible.

      It's encrypted. Not sure what with which key, but it's not plaintext, which is what they were responding too: > you can then go on your Mac and access the password in the list of saved wifi password Not true.

        In my case, searching for my network name in Keychain Access brings up 2 items, one in my System keychain and one in the iCloud one. Both of them end up displaying the raw password on the detail view now, though I do indeed remember that a year ago I saw some wireless passwords being in hex instead. I'm not denying they might be reversibly-encrypted (although this doesn't happen to me anymore for some reason), but in any case for a WPA(2)-PSK network the key cannot be hashed using a one-way irreversible hash because it is needed as-is to actually complete the authentication. What you're seeing is encryption and not hashing.
