Modify open source program

Modify the open source TrueCrypt program (<[login to view URL]>) and add a DLL interface to the program. Details see Deliverables section. **NOTE: The DLL only needs to interface with the TrueCrypt program. You don't have to add any new logic or features.** ## Deliverables **Task 1: **Take out the TrueCrypt ([[login to view URL]][1]) main GUI Program Menu window and its systray icon so that TrueCrypt will run in the background without any GUI. **Task 2: **Create a DLL which performs the tasks of the TrueCrypt GUI interface. The DLL should expose the following APIs: **1) DWORD TrueCryptStart(LPCWSTR szInstallDir);** Description: Simply runs [login to view URL] in that directory. Parameters: szInstallDir = TrueCrypt's installation directory Return value: Returns error code. Please review the TrueCrypt code and list possible error values. A zero should indicate the operation was successful. **2) DWORD TrueCryptCreateStandardVolume( LPCWSTR szFilename, LPCWSTR szEncryptionAlgorithm, LPCWSTR szHashAlgorithm, DWORD dwMaxSizeMBytes, LPCWSTR szPassword);** Description: This API carries out the tasks done by the TrueCrypt Volume Creation Wizard to create a standard regular (non-Dynamic) TrueCrypt volume using FAT filesystem and Default cluster size. Parameters: szFilename = full file path of the TrueCrypt volume file Possible values for szEncryptionAlgorithm: - AES - Serpent - Twofish - AES-Twofish - AES-Twofish-Serpent - Serpent-AES - Serpent-Twofish-AES - Twofish-Serpent Possible values for szHashAlgorithm: - Whirlpool - SHA-1 - RIPEMD-160 dwMaxSizeMBytes = maximum size of the encrypted volume in MB szPassword = password for the encrypted volume Return value: Returns error code. Please review the TrueCrypt code and list possible error values. A zero should indicate the operation was successful. **3) DWORD TrueCryptMountVolume( WCHAR chDriveLetter, LPCWSTR szFilename, LPCWSTR szPassword, BOOL bMountAsReadOnly, BOOL bMountAsRemovable); ** Description: Mount a TrueCrypt file as a volume at a specific drive letter. Parameters: chDriveLetter = drive letter to be used for mounting szFilename = full file path of the TrueCrypt volume file szPassword = password for the encrypted volume bMountAsReadOnly = Mount volue as read-only (see TrueCrypt - Mount Options window) bMountAsRemovable = Mount volume as removable medium Return value: Returns error code. Please review the TrueCrypt code and list possible error values. A zero should indicate the operation was successful. **4) DWORD TrueCryptDismountAll();** Description: Dismount all mounted volumes. Return value: Returns error code. Please review the TrueCrypt code and list possible error values. A zero should indicate the operation was successful. **5) DWORD TrueCryptExit();** Description: Close the TrueCrypt program gracefully. Do not use KillProcess, use some interprocess-communications means to notify TrueCrypt to exit. Return value: Returns error code. Please review the TrueCrypt code and list possible error values (Such as why it cannot exit). A zero should indicate the operation was successful. The following 2 APIs (6 & 7) aim to get the information in the TrueCrypt volumes information below: ![][2] ** 6) DWORD TrueCryptGetDriveLetterStatuses([IN] int * pDrives);** Description: Get the status of each drive letter. Parameters: pDrives = an array of integers of size 26 (that is, int[26]) When the function returns, each element in the array represents the status of the drive letter. The statuses can be one of the following values: 0 = drive letter not available for mounting 1 = drive letter is free for mounting TrueCrypt volumes 2 = drive letter is already mounted with a TrueCrypt volume Return value: Returns error code. Please review the TrueCrypt code and list possible error values. A zero should indicate the operation was successful. Example: int drives[26]; DWORD result = TrueCryptGetDriveLetters(drives); if (result == 0) { for (int i = 0; i < 26; i++) { switch (drives[i]) { case 0: wprintf(L"drive letter %c is not available for mounting\n", L'a' + i); break; case 1: wprintf(L"drive letter %c is available for mounting\n", L'a' + i); break; case 2: wprintf(L"drive letter %c is already mounted with a TrueCrypt volume\n", L'a' + i); break; } } } **7) DWORD TrueCryptGetVolumeProperties( WCHAR chDriveLetter, PWCHAR szFilename, int * size, PWCHAR szEncryptionAlgorithm, PWCHAR szType);** Description: Get the properties of the mounted volume. Parameters: chDriveLetter = drive letter with a TrueCrypt volume mounted szFilename = returns the volume's filename (can assume the buffer has MAX_PATH size) size = returns the size of the volume in BYTES szEncryptionAlgorithm = returns the encryption algorithm used e.g., "AES" (can assume the buffer has MAX_PATH size) szType = returns the type of the volume e.g., "Normal" (can assume the buffer has MAX_PATH size) ============== 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
