encryptElement

public static org.w3c.dom.Element encryptElement(org.w3c.dom.Element elemPlain,
                                                 java.lang.String password)
                                          throws java.lang.Exception

Encrypts an element and all its children using PKCS#12 and the given password. The encrypted Element replaces the plaintext Element inside its OwnerDocument. Note: The document Element cannot be encrypted using this function. For information on the XML encryption standard see also http://www.w3.org/TR/xmlenc-core/

Parameters:

elemPlain - Element to be encrypted (not the DocumentElement!)

password - String a password

Returns:

Element a pointer to the encrypted element

Throws:

java.lang.Exception

decryptElement

public static org.w3c.dom.Element decryptElement(org.w3c.dom.Element elemCrypt,
                                                 java.lang.String password)

elemCrypt - Element

password - String

Returns:

Element

Throws:

java.lang.Exception

decryptElement

public static org.w3c.dom.Element decryptElement(org.w3c.dom.Element elemCrypt,
                                                 IMiscPasswordReader a_passwordReader)
                                          throws java.lang.Exception

Throws:

java.lang.Exception

                                                   MyRSAPublicKey publicKey)

Returns a node which is the encrypted version of elemPlain.

Parameters:

elemPlain -

publicKey -

Returns:

the encrypted Element, or null if an error occured
