public class IdentityManager
extends Object

This class holds the identity of the node. Messages to the node are addressed to the identity. In a future release, messages will be signed and encrypted with public-private key pairs contained in the identity.

Constructor Detail

IdentityManager

public IdentityManager(DrasylConfig config)

Manages the identity at the specified file path. If there is no identity at this file path yet, a new one is created.

Method Detail

loadOrCreateIdentity

public void loadOrCreateIdentity()
                          throws IOException

Attempts to load the identity defined in the configuration: First it tries to read the key pair directly from the configuration. If no key pair is specified there, the identity is loaded from the identity file path specified in the configuration. If the file does not exist, a new identity is generated and written to the file. If all this fails and no identity can be loaded, an IOException is thrown.

Throws:

IOException - if identity could not be loaded or created

generateIdentity

public static Identity generateIdentity()
                                 throws IOException

Generates a new random identity.

Returns:

the generated identity

Throws:

IOException - if an identity could not be generated

getPublicKey

public CompressedPublicKey getPublicKey()

getPrivateKey

public CompressedPrivateKey getPrivateKey()

getProofOfWork

public ProofOfWork getProofOfWork()

getIdentity

public Identity getIdentity()

Returns:

returns the node identity.

deleteIdentityFile

public static void deleteIdentityFile(Path path)
                               throws IOException

Deletes the identity file specified in the configuration.

ATTENTION: Messages directed to the present identity can then no longer be decrypted and read. This step is irreversible. Should only be used if the present identity should never be used again!

Throws:

IOException - if identity file could not be deleted
