Xceed Encryption Library is an ActiveX component that allows Windows applications to encrypt and decrypt data using the latest industry standard strong encryption algorithms. It supports traditional secret-key encryption as well as public-key encryption, and can encrypt/decrypt memory buffers, strings, blobs, streaming data or files.
For traditional strong encryption, the library supports the newly adopted AES (US Advanced Encryption Standard) secret-key encryption algorithm (Rijndael), which uses 128, 192 or 256-bit keys. It also supports the Twofish encryption algorithm, a runner-up for AES. For public-key encryption, it offers the RSA algorithm unlimited key bit-sizes. It includes a test vector sample application with the test vectors required to demonstrate correct implementation of the encryption algorithms offered.
The library uses the modern SHA-2 and HAVAL hashing algorithms so that passphrases can be converted to exactly the amount of bits required for an encryption key and with better mathematical properties than older hashing algorithms such as MD5.
Like all Xceed components, this library is designed to be flexible yet extremely easy to use. In fact, it only takes one line of code to encrypt or decrypt memory or files. A single line of code can even be used to chain together multiple Xceed components like the Xceed Streaming Compression Library and the Xceed Binary Encoding Library, so you can compress, encrypt and encode data into text just as easily.
The fully self-contained ActiveX control at the core of the library is all you need to include with your projects. It has no external dependencies such as MFC DLLs, runtime libraries or other resources. That translates to minimal hassle at distribution time. The library also supports all the available ActiveX functionality designed to make your programming job easier, such as categorized properties, built-in constants and enumerations, context-sensitive F1-help, optional para

This high-performance Zip & Unzip data compression library lets your applications create and manipulate 100% PKZip compatible Zip files as well as compress/uncompress data directly in memory. Offers the ultimate flexibility and is the easiest to use product of its kind. Includes a state-of-the-art, fully documented ActiveX COM component that provides the industry's most complete feature set and the fastest multi-threaded compression engine.
This ActiveX component supports single-threaded (STA) and multi-threaded (MTA) apartment models and has very low memory requirements. Perfectly suited for use in environments running multiple zip/unzip operations simultaneously, can run in the background and can be dynamically instantiated for formless use.
Xceed Zip, already known for being superbly designed and easy to use, now offers categorized properties, built-in constants and enumerations, context-sensitive F1-help, optional parameters and built-in help strings.
With Xceed Zip, applications receive detailed information about the current compression activity, have full control over each file's information as it is being zipped and unzipped and can be consulted by the library when choices need to be made.
Xceed Zip is 100% compatible with the latest PKZip 4.5 zip file format as well as the traditional 2.04g format.
Xceed Zip includes comprehensive online documentation with examples to help you accomplish your tasks effortlessly. Fully commented sample applications are included for many languages. You can copy examples from the help file or samples, paste them into your project, and create a Zip files without writing a single line of code!
Xceed Zip includes complete sample applications, free expert support, and includes the multi-threaded ActiveX component, a DLL interface and an excellent 16-bit support package. It works with VB, VC++,Delphi, C++Builder, Visual FoxPro, ASP, VB Script, and most any other 32-bit Windows developm
