oracle.security.xmlsec.util.XMLElement
oracle.security.xmlsec.enc.XEEncryptedObject

Direct Known Subclasses:

XEEncryptedData, XEEncryptedKey

public abstract class XEEncryptedObject

extends XMLElement

Abstract class representing the XML-ENC EncryptedType structure. This is the base class for the XML-ENC encrypted elements EncryptedData and EncryptedKey.

The XEEncryptedObject's EncryptionMethod specifies the encryption or key wrapping algorithm to be used. Standard algorithm URI constants can be found in XMLURI, including:

• Encryption Methods:
  • AES-128 XMLURI.alg_aes128_CBC
  • AES-192 XMLURI.alg_aes192_CBC
  • AES-256 XMLURI.alg_aes256_CBC
  • Triple-DES XMLURI.alg_tripleDES_CBC
• Key Wrapping/Transport Methods:
  • AES-128 XMLURI.alg_kwAES128
  • AES-192 XMLURI.alg_kwAES192
  • AES-256 XMLURI.alg_kwAES256
  • Triple-DES XMLURI.alg_kwTripleDES
  • RSA-OAEP With MGF1 XMLURI.alg_rsaOAEP_MGF1
  • RSA-PKCS#1 v1.5 XMLURI.alg_rsaV15

An optional Type URI may be used to indicate the type of the encrypted object, which should be used where possible to aid in decryption processing. Standard encrypted object type URI constants can be found in XMLURI, including:

• XML Element XMLURI.obj_Element
• XML Element Content XMLURI.obj_Content
