Examples disclosed herein relate to symmetrically encrypting a master passphrase key. In one implementation, a computing system includes a machine-readable storage medium to store a symmetrically encrypted master passphrase key, an encrypted version of a first passphrase key associated with a second machine-readable storage medium encrypted using the master passphrase key, and an encrypted version of a second passphrase key associated with a third machine-readable storage medium encrypted using the passphrase key. A processing resource may symmetrically encrypt the master passphrase key using an encryption key derived from authentication information and/or decrypt the stored master passphrase key using a decryption key derived from the authentication information.

Symmetrically encrypt a master passphrase key

In some examples, a computing device can identify, by a processing resource of the computing device, an operating system (OS) uniform resource locator (URL) from a radio-frequency identification (RFID) chip coupled to the processing resource in response to the computing device being powered on, download from an OS repository an OS descriptor using the OS URL from the RFID chip and an OS image using the OS descriptor, and install an OS to a hard disk of the computing device using the OS image downloaded from the OS repository.
