Abstract: 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.
