Class SelfSignedGenerator

java.lang.Object

net.i2p.crypto.SelfSignedGenerator

public final class SelfSignedGenerator
extends Object

Generate keys and a selfsigned certificate, suitable for storing in a Keystore with KeyStoreUtil.storePrivateKey(). All done programatically, no keytool, no BC libs, no sun classes. Ref: RFC 2459, RFC 5280 This is coded to create a cert that is similar to what comes out of keytool. NOTE: Recommended use is via KeyStoreUtil.createKeys() and related methods. This API may not be stable.
