Immutable response model returned by

co.ankatech.ankasecure.sdk.AnkaSecureSdk#reencryptFile(java.nio.file.Path, String, String)
.

This class encapsulates a new Compact JWE after re-encrypting an existing payload with a different key. It provides metadata for both the old decryption key and the new encryption key used by the platform.

Payload handling

The SDK persists the Compact JWE into the outputFile specified by the caller, encoded with UTF-8. The string already contains all five Base64URL segments defined by RFC 7516: 
BASE64URL(ProtectedHeader).
 BASE64URL(EncryptedKey).
 BASE64URL(IV).
 BASE64URL(Ciphertext).
 BASE64URL(Tag)
The application can either keep the file intact or process the string with a third-party JWE library.

Key metadata

  • oldKeyRequested: the kid originally supplied for decryption.
  • oldKeyUsed: the effective kid used by the server for decryption after rotation/succession logic.
  • oldKeyAlgorithmUsed: the hybrid algorithm negotiated for decryption.
  • newKeyRequested: the kid originally supplied for encryption.
  • newKeyUsed: the effective kid used by the server for encryption after rotation/succession logic.
  • newKeyAlgorithmUsed: the hybrid algorithm negotiated for encryption.

Thread-safety

Instances are immutable data carriers after construction and may be shared across threads safely, provided no mutator is invoked.

All getters return non-null values except getWarnings(), which may be null if no warnings were issued.
