Constructor Detail

EncryptionMaterials

public EncryptionMaterials(KeyPair keyPair)

Constructs a new EncryptionMaterials object, storing an asymmetric key pair.

Parameters:

keyPair - The asymmetric key pair to be stored in this EncryptionMaterials object.

EncryptionMaterials

public EncryptionMaterials(SecretKey symmetricKey)

Constructs a new EncryptionMaterials object, storing a symmetric key.

Parameters:

symmetricKey - The symmetric key to be stored in this EncryptionMaterials object.

EncryptionMaterials

protected EncryptionMaterials(KeyPair keyPair,
                              SecretKey symmetricKey)

Base constructor for the EncryptionMaterials object. This is not publicly visible since it should not be possible to create an EncryptionMaterials object that contains both an asymmetric key pair and a symmetric key.

Method Detail

getKeyPair

public KeyPair getKeyPair()

Returns the key pair stored in this EncryptionMaterials object.

Returns:

the key pair stored in this EncryptionMaterials object.

getSymmetricKey

public SecretKey getSymmetricKey()

Returns the symmetric key stored in this EncryptionMaterials object.

Returns:

the symmetric key stored in this EncryptionMaterials object.

getMaterialsDescription

public Map<String,String> getMaterialsDescription()

Returns a snapshot of the current material description; never null.

getAccessor

public EncryptionMaterialsAccessor getAccessor()

Returns null since the EncryptionMaterials base class does not have a materials accessor. Subclasses may override this method.

Returns:

null

addDescription

public EncryptionMaterials addDescription(String name,
                                          String value)

Fluent API to add material description.

addDescriptions

public EncryptionMaterials addDescriptions(Map<String,String> descriptions)

Fluent API to add all the given material descriptions.

isKMSEnabled

public boolean isKMSEnabled()

Returns true if this is a KMS material description; false otherwise.

Returns:

false by default

getCustomerMasterKeyId

public String getCustomerMasterKeyId()

Throws:

UnsupportedOperationException - by default

getDescription

protected String getDescription(String name)
