class DynamicEncryptedMessageMaker

Defined at line 76 of file ../../third_party/cobalt/src/lib/util/dynamic_encrypted_message_maker.h

Thread-safe, hot-swappable EncryptedMessageMaker that validates key expiration

against a system wall clock before encrypting each message.

Public Methods

void DynamicEncryptedMessageMaker (SystemClockInterface * clock)

Constructs an uninitialized DynamicEncryptedMessageMaker. Calls to Encrypt()

will return false until UpdateKey() provides a valid key.

|clock| must be non-null and must outlive this instance.

void DynamicEncryptedMessageMaker (ParsedKey initial_key, SystemClockInterface * clock)

Constructs a DynamicEncryptedMessageMaker initialized with |initial_key|.

|clock| must be non-null and must outlive this instance.

bool Encrypt (const google::protobuf::MessageLite & message, EncryptedMessage * encrypted_message)

void UpdateKey (ParsedKey new_key)

bool IsExpired ()

Returns true if the maker is initialized with a key whose expiration

timestamp has passed. Returns false if the maker is uninitialized; callers

should also check IsInitialized() to determine whether the maker has a

valid key ready for encryption.

int64_t expiration_timestamp_secs ()

Expiration timestamp of the current key in seconds since the Unix epoch,

compared against SystemClockInterface::now(). Returns 0 if uninitialized.
