masked-key encryptedKey
Command introduced before JUNOSe Release 7.1.0.
Specifies the encrypted form of the preshared key that the router uses in IKE negotiations. Once you enter a preshared key, the router encrypts the key and displays it in masked form to increase the security of the key. If you need to reenter the key, you can enter it in its masked form using this command. There is no no version. To delete a key, use the no version of the ipsec key manual command.
