Modifier and Type	Method	Description
`void`	`initialize(Properties props)`

- Method Detail
  - initialize
```
void initialize(Properties props)
```
  - isTrusted
```
boolean isTrusted(String asserterAddress,
                  String messageDirection,
                  X509Certificate securityid,
                  Principal[] pAssertedValues)
```
    determines if the container can trust the network entity from which we received the message with P-Asserted-Identity header. This method also validates if the identity that was used to secure(eg: SSL) the message is trusted.
    
    Parameters:
    
    pAssertedValues - P-Asserted-Identity header values
    
    messageDirection - "Incoming" if this method is invoked for a incoming request, "Outgoing" if the message is being sent out.
    
    asserterAddress - ipaddress/hostname of the network entity from which we received the SIP message with P-Asserted-Identity header. Inorder to accept/use the values in P-Asserted-Identity header the network entity should be a trusted.
    
    securityid - is the asserting security identity, if a secure connection is used then this would be the java.security.cert.X509Certificate, else null.
    
    Returns:
    
    true if we trust the networtid and the securityid.
