Package com.amazonaws.encryptionsdk

Class ParsedCiphertext

java.lang.Object

com.amazonaws.encryptionsdk.model.CiphertextHeaders

com.amazonaws.encryptionsdk.ParsedCiphertext

public class ParsedCiphertext
extends CiphertextHeaders

Exposes header information of ciphertexts to make it easier to inspect the algorithm, keys, and encryption context prior to decryption.

Please note that the class does not make defensive copies.

Constructor Details

ParsedCiphertext

public ParsedCiphertext(byte[] ciphertext,
 int maxEncryptedDataKeys)

Parses ciphertext. Please note that this does not make a defensive copy of ciphertext and that any changes made to the backing array will be reflected here as well.

Parameters:

ciphertext - The ciphertext to parse

maxEncryptedDataKeys - The maximum number of encrypted data keys to parse. Zero indicates no maximum.

ParsedCiphertext

public ParsedCiphertext(byte[] ciphertext)

Parses ciphertext without enforcing a max EDK count. Please note that this does not make a defensive copy of ciphertext and that any changes made to the backing array will be reflected here as well.

Method Details

getCiphertext

public byte[] getCiphertext()

Returns the raw ciphertext backing this object. This is not a defensive copy and so must not be modified by callers.

getOffset

public int getOffset()

The offset at which the first non-header byte in ciphertext is located.
