JXTA in a Nutshell

Name

PublicKeyAlgorithm

Synopsis

Classes that implement this interface are used to create public key objects. The JXTA crypto implementation for the platform may obtain an object that implements this interface.

When you want to create a new public key (and its corresponding private key), you obtain the PublicKeyAlgorithm object and call the setPublicKey( ) and setPrivateKey( ) methods without any arguments. This calculates and creates a new public/private key pair. The data representing the public and private keys can be obtained from the getPublickey( ) and getPrivatekey( ) methods.

Conversely, if you’re working with an existing public/private key pair, store the public key data in a PublickeyData object (and the private key data in a PrivatekeyData object) and use these objects to initialize the PublicKeyAlgorithm object by passing them to the appropriate setPublickey( ) and setPrivatekey( ) methods.
