TableFieldQueue* KeyManager::CreateDefinition()

Creates definition of acTable - used only in constructor. The records from the table have 3 fields: ACID, PUB_KEY and PRIVATE_KEY.

Returns:

tableFieldQueue - model queue

GMessage* KeyManager::GetMixPublicKey(char * , char * )

Returns Mix public key. Extracts public part from asymetric key and returns it.

Returns:

Pointer to GMessage containing asymetric public key.

GMessage* KeyManager::GetPrivKeyByACID(ACID acID)

Finds the key according to its keyID. Returns private key associated with ACID from the keyManager's table.

Returns:

privKey (GMessage)

Parameters:

acid - ACID to find the key with.

KeyManager::KeyManager(ConfigFile *keyManagerConfigFile, LogFile * keyManagerLogFile, Cipherer *keyManagerCipherer, MessageQueue *keyManagerMessageQueue)

Key manager constructor. Stores pointers to objects that are need later for various tasks.
It also loads keys saved on disk into memory in case someone wants it.

Parameters:

keyManagerConfigFile - Pointer to cinfig that we ask for configuration options.
keyManagerLogFile - Log file that we have to write debug messages to.
keyManagerCipherer - Cipherer object that is used for key generation.
keyManagerMessageQueue - Message queue that is used for publishing keys.

KeyManager::KeyManager(LogFile *aLogFile, Char* aTableName)

Constructor of keyManager. Creates the keyManager table.

Parameters:

logFile - keyManager logFile
aTableName - Name of file to create keyManager table in.

Author:

See Also:

Err KeyManager::LoadAsymetricKeyPairIntoMemory()

Loads asymetric keys from disk. If there is a problem loading keys then an error is reported and exit called.

Returns:

OK if success else KO.

Err KeyManager::SaveKeys(ACID acid, GMessage *pubKey, GMessage *privKey)

Inserts keys into the table. Saves public and private key together with the associated ACID.

Returns:

error code

Parameters:

acid - Acid to save.
pubKey - PubKey to save.
privKey - PrivKey to save.
