Class WSSecEncryptedKey

  • Direct Known Subclasses:
    WSSecEncrypt
    public class WSSecEncryptedKey
extends WSSecBase
    Builder class to build an EncryptedKey. This is especially useful in the case where the same EncryptedKey has to be used to sign and encrypt the message In such a situation this builder will add the EncryptedKey to the security header and we can use the information form the builder to provide to other builders to reference to the token

      • setUserInfo

        public void setUserInfo​(String user)
        Set the user name to get the encryption certificate. The public key of this certificate is used, thus no password necessary. The user name is a keystore alias usually.
        Parameters:
        user -

      • getId

        public String getId()
        Get the id generated during prepare(). Returns the the value of wsu:Id attribute of the EncryptedKey element.
        Returns:
        Return the wsu:Id of this token or null if prepare() was not called before.

      • prepare

        public void prepare​(Crypto crypto,
                    SecretKey symmetricKey)
             throws WSSecurityException
        Create the EncryptedKey Element for inclusion in the security header, by encrypting the symmetricKey parameter using either a public key or certificate that is set on the class, and adding the encrypted bytes as the CipherValue of the EncryptedKey element. The KeyInfo is constructed according to the keyIdentifierType and also the type of the encrypting key
        Parameters:
        crypto - An instance of the Crypto API to handle keystore and certificates
        symmetricKey - The symmetric key to encrypt and insert into the EncryptedKey
        Throws:
        WSSecurityException

      • addCipherValueElement

                              throws WSSecurityException
        Create and add the CipherValue Element to the EncryptedKey Element.
        Throws:
        WSSecurityException

      • createEncryptedKeyElement

        protected void createEncryptedKeyElement​(X509Certificate remoteCert,

                                  throws WSSecurityException
        Now we need to setup the EncryptedKey header block: 1) create a EncryptedKey element and set a wsu:Id for it 2) Generate ds:KeyInfo element, this wraps the wsse:SecurityTokenReference 3) Create and set up the SecurityTokenReference according to the keyIdentifier parameter 4) Create the CipherValue element structure and insert the encrypted session key
        Throws:
        WSSecurityException
