Example 1 with GarlicClove

Example 2 with GarlicClove

use of net.i2p.data.i2np.GarlicClove in project i2p.i2p by i2p.

the class GarlicMessageBuilder method buildClove.

/**
 *  UNUSED
 *
 *  The Garlic Message we are building contains another garlic message,
 *  as specified by a GarlicConfig (NOT a PayloadGarlicConfig).
 *
 *  So this calls back to the top, to buildMessage(ctx, config),
 *  which uses the router's SKM, i.e. the wrong one.
 *  Unfortunately we've lost the reference to the SessionKeyManager way down here,
 *  so we can't call buildMessage(ctx, config, key, tags, skm).
 *
 *  If we do ever end up constructing a garlic message that contains a garlic message,
 *  we'll have to fix this by passing the skm through the last buildMessage,
 *  through buildCloveSet, to here.
