      • isBlindedWhenPublished

        public boolean isBlindedWhenPublished()
        Set if the unencrypted LS, when published, will be blinded/encrypted
        Since:
        0.9.42

      • setBlindedWhenPublished

        public void setBlindedWhenPublished()

        Throws:
        IllegalStateException - if already signed

        0.9.42

      • getReceivedAsPublished

        public boolean getReceivedAsPublished()
        If true, we received this LeaseSet by a remote peer publishing it to us, AND the unpublished flag is not set. Default false.
        Overrides:
        getReceivedAsPublished in class LeaseSet
        Since:
        0.9.39 overridden

      • getEncryptionKey

        public PublicKey getEncryptionKey()
        If more than one key, return the first supported one. If none supported, return the first one.
        Overrides:
        getEncryptionKey in class LeaseSet
        Since:
        0.9.39 overridden

      • getEncryptionKey

        public PublicKey getEncryptionKey​(Set<EncType> supported)
        If more than one key, return the first supported one. If none supported, return null.
        Overrides:
        getEncryptionKey in class LeaseSet
        Parameters:
        supported - what return types are allowed
        Returns:

      • addEncryptionKey

        public void addEncryptionKey​(PublicKey key)
        Add an encryption key. Encryption keys should be added in order of server preference, most-preferred first.

      • getEncryptionKeys

        public List<PublicKey> getEncryptionKeys()
        This returns all the keys. getEncryptionKey() returns the first one. Encryption keys should be in order of server preference, most-preferred first. Client behavior should be to select the first key with a supported encryption type. Clients may use other selection algorithms based on encryption support, relative performance, and other factors.
        Returns:
        not a copy, do not modify, null if none

      • setOptions

        public void setOptions​(Properties options)

        Since:
        0.9.39

      • encrypt

        public void encrypt​(SessionKey key)
        Description copied from class: LeaseSet
        Encrypt the gateway and tunnel ID of each lease, leaving the expire dates unchanged. This adds an extra dummy lease, because AES data must be padded to 16 bytes. The fact that it is encrypted is not stored anywhere. Must be called after all the leases are in place, but before sign().
        Overrides:
        encrypt in class LeaseSet
