Supports multiple instances running simultaneously

An encryption library with fast, low memory usage algorithms that supports file-based encryption/decryption as well as streaming

Robust and Reliable

Supports various industry standard encryption algorithms

Works with buffers, streams, or files.

Supports multiple instances running simultaneously.

Highest quality design

A versatile library that makes it easy for your app to perform a variety of encryption-related tasks. Encrypt or decrypt, digitally sign, hash, authenticate, digital envelope, and more.

Performs strong AES symmetrical encryption/decryption with 128-, 192-, or 256-bit keys. Or use public-key encryption with the RSA algorithm. Also supports Twofish, SHA-2, ECB and CBC, and more. Includes a random number generator that can warn your app if there is not enough entropy.

Technically superior

One fully self-contained object, written with ATL 3.0 for no external dependencies, STA and MTA multi-threaded apartment models, fast and efficient.

A single fully self-contained COM object and ActiveX control written with ATL 3.0.
Requires no external DLLs, ATL, MFC, or runtime libraries.
Both single-threaded (STA) and multi-threaded apartment (MTA) model design.
Instantiate the component dynamically without putting it on a form.
Supports multiple instances running simultaneously.
Uses native Unicode API calls for best performance.
ActiveX control interface has all constants, enumerations, and types built in. Code completion, property categories, help strings, and context-sensitive F1 help fully supported.
Works with all 32-bit development environments that can use ActiveX controls, including VB, VC++, Delphi, C++ Builder, VFP, Office, Web scripting languages, ASP, and DCOM projects.

Supports both strong secret-key encryption and public-key encryption.
Supports AES (Advanced Encryption Standard / Rijndael) algorithm, the Twofish algorithm, and the RSA encryption algorithm (RSAES-OAEP).
Secret-key (symmetrical) encryption support for 128-, 192-, or 256-bit keys.
Public-key (asymmetrical) encryption supports keys of 338 bits and up.
Supports Electronic Code Book (ECB) and Cipher Block Chaining (CBC) encryption modes.
Offers the SHA-2 hash functions.

RFC-2437 compliant.
Fast, low memory usage algorithms.
Encrypt and decrypt data.
Digitally sign data.
Verify data against a digital signature.
Hash data (create message digests).
Sophisticated random number generator.
Process data directly from one memory buffer to another.
Process data from file to memory or from memory to file.
Process data from one file to another.
All function modes support streaming data.
Settable initialization vector for Cipher Block Chaining encryption mode.
Compare data byte-for-byte.
Offers all the tools you need to create a digital envelope.
Can efficiently work with the streaming compression library included with Xceed Zip for ActiveX, and/or Xceed Encoding for ActiveX to compress, decompress, encode, or decode data before encrypting or decrypting it, in a single pass.

Complete, comprehensive documentation provided in an MSDN-style HTML format which is fully context-sensitive so that pressing F1 on a keyword in your IDE opens up the manual to the correct relevant topic.
