Powerful LockBox3 Cryptography Library Available For Delphi And C++Builder

LockBox3 is a Delphi library for cryptography. It provides support for AES, DES, 3DES, Blowfish, Twofish, SHA, MD5, a variety of chaining modes, RSA digital signature and verification.

This is a source-only release of TurboPack LockBox3. It includes designtime and runtime packages for Delphi and C++Builder and supports VCL, FMX, Win32, Win64, macOS, iOS, and Android.


Reading the information from http://lockbox.seanbdurkin.id.au/HomePage, “the user interface shall be clean and simple. For Ciphers and Hashes, two styles shall be provided: A component and an interface pointer. IV, salting of ciphers and signaling of IV’s shall be managed and hidden from the developer-client. The main encryption functions shall be implemented in 100% native Delphi code. (TOpenSSL_Signatory component is the exception to the rule).

That is to say it shall not rely on links to third party libraries (at least as far as the core functionality is concerned).

LockBox 3 is has easy traceability to standards. Developers should be able to open cipher standards and open the respective implementing source code; put them side-by-side, and very quickly observer that one implements the other.

implementing source should borrow the style and symbols and the specifiying cipher standard.It shall be as easy as it can be to extend the library with new hashes and block ciphers. The selection, implementation and usage of ciphers shall be divorced from the chaining mode.

LockBox3CR.bpl (C++Builder Runtime) and LockBox3CD.bpl (C++Builder Designtime).

TurboPack LockBox3 is available via the GetIt Package Manager where you can quickly and easily install and uninstall it.

To manually install TurboPack LockBox3 into your IDE, take the following steps:

  • Unzip the release files into a directory (e.g., d:lockBox3);
  • Start RAD Studio;
  • Add the source directory (e.g. d:lockBox3run and all the subdirectories) to the IDE’s library path. For C++Builder, add the hpp subdirectory (e.g., d:lockBox3sourcehppWin32Release) to the IDE’s system include path;
  • Open & install the designtime package specific to the IDE being used. The IDE should notify you the components have been installed;

I can tell for sure that this is the best choice for cryptography library !
