## Package net.i2p.data

Interface Summary
DataStructure: Defines the class as a standard object with particular bit representation, exposing methods to read and write that representation.

Class Summary
Address
Base64: Encodes and decodes to and from Base64 notation.
ByteArray: Wrap up an array of bytes so that they can be compared and placed in hashes, maps, and the like.
Certificate: Defines a certificate that can be attached to various I2P structures, such as RouterIdentity and Destination, allowing routers and clients to help manage denial of service attacks and the network utilization.
DataHelper: Defines some simple IO routines for dealing with marshalling data structures
DataStructureImpl: Base implementation of all data structures
Destination: Defines an end point in the I2P network.
Hash: Defines the hash as defined by the I2P data structure spec.
Lease: Defines the proof that a particular router / tunnel is allowed to receive messages for a particular Destination during some period of time.
LeaseSet: Defines the set of leases a destination currently has.
Payload: Defines the actual payload of a message being delivered, including the standard encryption wrapping, as defined by the I2P data structure spec.
PrivateKey: Defines the PrivateKey as defined by the I2P data structure spec.
PublicKey: Defines the PublicKey as defined by the I2P data structure spec.
RouterAddress: Defines a method of communicating with a router
RouterIdentity: Defines the unique identifier of a router, including any certificate or public key.
RouterInfo: Defines the data that a router either publishes to the global routing table or provides to trusted peers.
RoutingKeyGenerator: Component to manage the munging of hashes into routing keys - given a hash, perform some consistent transformation against it and return the result.
SessionKey: Defines the SessionKey as defined by the I2P data structure spec.
SessionTag
Signature: Defines the signature as defined by the I2P data structure spec.
SigningPrivateKey: Defines the SigningPrivateKey as defined by the I2P data structure spec.
SigningPublicKey: Defines the SigningPublicKey as defined by the I2P data structure spec.
TunnelId: Defines the tunnel ID that messages are passed through on a set of routers.

Exception Summary
DataFormatException: Thrown when the data was not available to read or write a DataStructure
