Constructor Detail

EncryptedLeaseSet

public EncryptedLeaseSet()

Method Detail

getType

public int getType()

Description copied from class: DatabaseEntry

Get the type of the data structure. This should be faster than instanceof.

Overrides:

getType in class LeaseSet2

Returns:

KEY_TYPE_ROUTERINFO or KEY_TYPE_LEASESET or LS2 types

getLeaseCount

public int getLeaseCount()

Overrides:

getLeaseCount in class LeaseSet

Returns:

0-16, or 0 if not decrypted.

getLease

public Lease getLease(int index)

Overrides:

getLease in class LeaseSet

Returns:

null if not decrypted.

setDestination

public void setDestination(Destination dest)

Overridden to set the blinded key

Overrides:

setDestination in class LeaseSet

Parameters:

dest - non-null, must be EdDSA_SHA512_Ed25519

Throws:

IllegalStateException - if already signed

IllegalArgumentException - if not EdDSA

getSigningPublicKey

protected SigningPublicKey getSigningPublicKey()

Overridden to return the blinded key so super.verifySignature() will work.

Overrides:

getSigningPublicKey in class DatabaseEntry

Returns:

SPK or null

readBytes

public void readBytes(InputStream in)
               throws DataFormatException,
                      IOException

This does NOT validate the signature

Specified by:

readBytes in interface DataStructure

Overrides:

readBytes in class LeaseSet2

Parameters:

in - stream to read from

Throws:

IllegalStateException - if called more than once or Destination already set

DataFormatException - if the data is improperly formatted

IOException - if there was a problem reading the stream

writeBytesWithoutSig

protected void writeBytesWithoutSig(OutputStream out)
                             throws DataFormatException,
                                    IOException

Without sig. This does NOT validate the signature

Overrides:

writeBytesWithoutSig in class LeaseSet2

Throws:

DataFormatException

IOException

verifyOfflineSignature

public boolean verifyOfflineSignature()

Overridden because we have a blinded key, not a dest

Overrides:

verifyOfflineSignature in class LeaseSet2

readHeader

protected void readHeader(InputStream in)
                   throws DataFormatException,
                          IOException

Overridden because we have a blinded key, not a dest

Overrides:

readHeader in class LeaseSet2

Throws:

DataFormatException

IOException

writeHeader

protected void writeHeader(OutputStream out)
                    throws DataFormatException,
                           IOException

Overridden because we have a blinded key, not a dest

Overrides:

writeHeader in class LeaseSet2

Throws:

DataFormatException

IOException

readOfflineBytes

protected void readOfflineBytes(InputStream in)
                         throws DataFormatException,
                                IOException

Overridden because we have a blinded key, not a dest

Overrides:

readOfflineBytes in class LeaseSet2

Throws:

DataFormatException

IOException

writeOfflineBytes

protected void writeOfflineBytes(OutputStream out)
                          throws DataFormatException,
                                 IOException

Overridden because we have a blinded key, not a dest

Overrides:

writeOfflineBytes in class LeaseSet2

Throws:

DataFormatException

IOException

size

public int size()

Number of bytes, NOT including signature

Overrides:

size in class LeaseSet2

getHash

public Hash getHash()

Overrides:

getHash in class DatabaseEntry

Returns:

Hash or null

Throws:

IllegalStateException

encrypt

public void encrypt(SessionKey key)

Throws IllegalStateException if not initialized.

Overrides:

encrypt in class LeaseSet2

Parameters:
