  - getNamespacePrefix
```
public String getNamespacePrefix(String namespaceURI,
                        String defaultPrefix)
```
    This implementation uses an internal HashMap to get the prefix that the specified URI maps to. It returns the defaultPrefix if it maps to null.
    
    Specified by:
    
    getNamespacePrefix in interface XMLCryptoContext
    
    Parameters:
    namespaceURI - a namespace URI
    defaultPrefix - the prefix to be returned in the event that the the specified namespace URI has not been bound to a prefix.
    
    Returns:
    the prefix that is associated with the specified namespace URI, or defaultPrefix if the URI is not registered. If the namespace URI is registered but has no prefix, an empty string ("") is returned.
    
    Throws:
    
    NullPointerException - if namespaceURI is null
    See Also:
    XMLCryptoContext.putNamespacePrefix(String, String)
  - putNamespacePrefix
```
public String putNamespacePrefix(String namespaceURI,
                        String prefix)
```
    This implementation uses an internal HashMap to map the URI to the specified prefix.
    
    Specified by:
    
    putNamespacePrefix in interface XMLCryptoContext
    
    Parameters:
    namespaceURI - a namespace URI
    prefix - a namespace prefix (or null to remove any existing mapping). Specifying the empty string ("") binds no prefix to the namespace URI.
    
    Returns:
    the previous prefix associated with the specified namespace URI, or null if there was none
    
    Throws:
    
    NullPointerException - if namespaceURI is null

The mappings are returned in no particular order. Each element in the iteration is represented as a Map.Entry. If the DOMCryptoContext is modified while an iteration is in progress, the results of the iteration are undefined.
    
    Returns:
    a read-only iterator over the set of mappings
