All Implemented Interfaces:

CapabilitySpec, edu.utah.janosvm.kit.comm.jsi.JSIHandler

public final class PublicKey

extends PublicKeySpec

implements edu.utah.janosvm.kit.comm.jsi.JSIHandler

A PublicKey capability wraps a java.security.PublicKey object. This makes it possible to pass the object to untrusted code without leaking the key material.

Field Summary

static PermissionSet	DEFAULT_PERMISSIONS The default permissions for a new PublicKey capability.
static Permission	READ_ENCODED_PERMISSION Permission to read the encoded version of this key.

Fields inherited from class bees.core.Capability

Constructor Summary

PublicKey()
Construct an empty PublicKey capability.
