Method Detail

getEncryptionContext

Map<String,String> getEncryptionContext()

Return the encryption context used in the generation of the data key used for the encryption of content.

During decryption, this value should be obtained by parsing the ciphertext headers that encodes this value.

Returns:

the key-value map containing the encryption context.

getHeaders

CiphertextHeaders getHeaders()

getMasterKeys

List<K> getMasterKeys()

All used MasterKeys. For encryption flows, these are all the MasterKeys used to protect the data. In the decryption flow, it is the single MasterKey actually used to decrypt the data.
