Package net.i2p.data

Class KeysAndCert

java.lang.Object
net.i2p.data.DataStructureImpl
net.i2p.data.KeysAndCert
All Implemented Interfaces:
Serializable, DataStructure
Direct Known Subclasses:
Destination, RouterIdentity
public class KeysAndCert extends DataStructureImpl
KeysAndCert has a public key, a signing key, and a certificate. In that order. We also store a cached Hash. Implemented in 0.8.2 and retrofitted over Destination and RouterIdentity. There's actually no difference between the two of them. As of 0.9.9 this data structure is immutable after the two keys and the certificate are set; attempts to change them will throw an IllegalStateException.
Since:
0.8.2

    • readBytes

      public void readBytes(InputStream in) throws DataFormatException, IOException
      Description copied from interface: DataStructure
      Load up the current object with data from the given stream. Data loaded this way must match the I2P data structure specification. Warning - many classes will throw IllegalStateException if data is already set.
      Parameters:
      in - stream to read from
      Throws:
      IllegalStateException - if data already set
      DataFormatException - if the data is improperly formatted
      IOException - if there was a problem reading the stream

      Parameters:
      out - stream to write to
      Throws:
      DataFormatException - if the data was incomplete or not yet ready to be written
      IOException - if there was a problem writing to the stream
