Class CipherTextSerializer
java.lang.Object
org.owasp.esapi.crypto.CipherTextSerializer
public class CipherTextSerializer
- extends Object
Helper class to assist with programming language and platform independent
serialization of CipherText
objects. The serialization is done in
network-byte order which is the same as big-endian byte order.
This serialization scheme is documented in
Format of Portable Serialization of org.owasp.esapi.crypto.CipherText Objects
.
Other serialization schemes may be desirable and could be supported (notably, RFC 5083 - Cryptographic
Message Syntax (CMS) Authenticated-Enveloped-Data Content Type, or CMS' predecessor,
PKCS#7 (RFC 2315)), but these serialization schemes are by comparison very complicated,
and do not have extensive support for the various implementation languages which ESAPI
supports. (Perhaps wishful thinking that other ESAPI implementations such as
ESAPI for .NET, ESAPI for C, ESAPI for C++, etc. will all support a single, common
serialization technique so they could exchange encrypted data.)

CipherTextSerializer
public CipherTextSerializer(byte[] cipherTextSerializedBytes)
throws EncryptionException
- Given byte array in network byte order (i.e., big-endian order), convert
it so that a
CipherText
can be constructed from it.
- Parameters:
cipherTextSerializedBytes
- A serialized CipherText
object
with the bytes in network byte order.
- Throws:
EncryptionException
- Thrown if a valid CipherText
object
cannot be reconstructed from the byte array.
asSerializedByteArray
public byte[] asSerializedByteArray()
- Return this
CipherText
object as a specialized, portable
serialized byte array.
- Returns:
- A serialization of this object. Note that this is not the
Java serialization.
asCipherText
public CipherText asCipherText()
- Return the actual
CipherText
object.
- Returns:
- The
CipherText
object that we are serializing.
