 or not it is considered "trusted" in that scope</td>
  <td>The scope that is printed out may be a filename, in which case
 it may convey local system information. For example, here's a sample
 printout of an identity named "carol", who is
 marked not trusted in the user's identity database:<br>

   <td>clearProviderProperties.{provider name}</td>
   <td>"Clearing" of a Provider so that it no longer contains the properties
 used to look up services implemented by the provider</td>
   <td>This disables the lookup of services implemented by the provider.
 This may thus change the behavior or disable execution of other
 parts of the program that would normally utilize the Provider, as
 described under the "removeProvider.{provider name}" permission.</td>

   <td>putProviderProperty.{provider name}</td>
   <td>Setting of properties for the specified Provider</td>
   <td>The provider properties each specify the name and location
 of a particular service implemented by the provider. By granting
 this permission, you let code replace the service specification
 with another one, thereby specifying a different implementation.</td>

   <td>removeProviderProperty.{provider name}</td>
   <td>Removal of properties from the specified Provider</td>
   <td>This disables the lookup of services implemented by the
 provider. They are no longer accessible due to removal of the properties
 specifying their names and locations. This
 may change the behavior or disable execution of other
 parts of the program that would normally utilize the Provider, as
 described under the "removeProvider.{provider name}" permission.</td>

 <tr>
   <td>getSignerPrivateKey</td>
   <td>Retrieval of a Signer's private key</td>
   <td>It is very dangerous to allow access to a private key; private
 keys are supposed to be kept secret. Otherwise, code can use the
 private key to sign various files and claim the signature came from
 the Signer.</td>
 </tr>

 <tr>
   <td>setSignerKeyPair</td>
   <td>Setting of the key pair (public key and private key) for a Signer</td>
   <td>This would allow an attacker to replace somebody else's (the "target's")
 keypair with a possibly weaker keypair (e.g., a keypair of a smaller
 keysize).  This also would allow the attacker to listen in on encrypted
 communication between the target and its peers. The target's peers
 might wrap an encryption session key under the target's "new" public
 key, which would allow the attacker (who possesses the corresponding
 private key) to unwrap the session key and decipher the communication
 data encrypted under that session key.</td>
