Constructor Detail

EncryptionKey

public EncryptionKey(EncryptionType keyType,
                     byte[] keyValue)

Creates a new instance of EncryptionKey.

Parameters:

keyType -

keyValue -

EncryptionKey

public EncryptionKey(EncryptionType keyType,
                     byte[] keyValue,
                     int keyVersion)

Creates a new instance of EncryptionKey. This constructor supports 'keyVersion', which is sent over the wire as part of EncryptedData but makes more sense in the domain model to have here as part of the key itself. Therefore, the keyVersion should only be constructor-injected when EncryptionKey's are retrieved from persisted storage.

Parameters:

keyType -

keyValue -

keyVersion -

Method Detail

destroy

public void destroy()

Returns:

The key version.

equals

public boolean equals(java.lang.Object o)

Overrides:
