CryptoSys APIThe CryptoSys API is a developer's toolkit of fast, efficient cryptographic functions in Visual Basic, VBA, VB.NET/VB2005/8, C/C++, C#, and ASP. It can be called from VBA applications like Access, Excel and Word. It provides four of the major block cipher algorithms, a stream cipher algorithm, key wrap, secure message digest hash algorithms, the HMAC message authentication algorithm, the CMAC algorithm, a data compression facility, a password-based key derivation function (PBKDF2), a secure random number generator and other utilities. If you need to do public key cryptography, see our alternative product CryptoSys PKI Toolkit.

I downloaded the Personal package about two hours ago, and my application is up and running with no problems!
You have done a great job.
-Anthony W.
First thanks for the great documentation with your product.
I had spent three days trying some other solutions to my HMAC problem,
and 1 hour after downloading your trial, my problem was solved.
-James S.
For developers, your product is great.
-Mark H, US Navy
Thanks for putting together such a great and easy to use library.
Your product is great and support is excellent as well.
-Mark W.
Thanks for an awesome product!
-James H.
Thank you very much. Your software worked great for our project.
-Chris C.
Thanks for your quick response. And thanks for Cryptosys API and other related
tools. You have done a great job.
I like the fact that Cryptosys comes in the form
of a DLL whose cipher algorithms can be called from VB and C/C++.
-Jalal R.
Thanks for your response...truly stellar, and I appreciate your
company's great product.
-Steve J.
One finds that rarely! So clear information and so clean program code:
ACCESS VBA, CryptoSys API, Cryptography generally. Thank you!
-Felix S.
Thank you very much. This answers our questions and we have everything working correctly.
Your support was very timely and precise. We are very pleased to have worked with you.
-Dan B.
The
CryptoSys API was easy to master and provided ARMP with a fast solution
to our Smart Card encryption software developed with Visual Basic.

The block cipher algorithms in the CryptoSys API are:
The one-way message digest hash functions the Secure Hash Algorithm (SHA-1), the stronger SHA-256 version, and SHA-224, SHA-384, SHA-512, MD5, MD2 and RIPEMD-160. The stream cipher (PC1) is fully compatible with RC4. The random number generator complies with the Federal Information Processing Standards Publication FIPS PUB 140-2 Security Requirements for Cryptographic Modules. Data compression functions are included based on Jean-loup Gailly's excellent 'zlib' product. We suggest one way of using compression with CryptoSys and show how to store the compressed plaintext in a simple packet structure before encryption. Another technique of compression and encryption is shown in our demonstration VB6 project of MySecret with CryptoSys API.
New Random Number Generator (RNG): Version 4 of CryptoSys API includes a new improved thread-safe random number generator (RNG) based on the strict NIST SP 800-90 standard. This is compliant with FIPS PUB 140-2. To that end, we publish the full details of the random number algorithms used in CryptoSys. Your comments and review are welcome.
The CryptoSys API functions allow you to encrypt, decrypt, hash and authenticate data in a variety of formats, as well as generating secure random keys to use in your applications. Your input data can generally be in a byte array, encoded as a hexadecimal string, or in a file. The functions can process the data in a one-off manner, or, for longer inputs, you can call the "update" functions sequentially after initialising. The block cipher algorithms work in Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB) and Counter (CTR) modes. AES with Galois/Counter Mode (AES-GCM) is provided. You can generate random keys and nonces in a secure manner. All functions are thread-safe. See the Examples page.
GCM_Encrypt.WIPE_File function - up to three times faster for large files.There are over 200 cryptographic functions in the CryptoSys API. The installed footprint is relatively small, about 450 kB. It comes with an easy to use installation program, demo projects, sample test source code, and a complete manual with examples.
The CryptoSys API uses a straightforward and independent Win32 DLL which is compatible with all versions of 32-bit Windows (95/98/Me/NT4/2K/XP/2003/Vista). There is no "COM", no "Active-X", and no requirement to "register" it with Windows to use it. The products do not use or rely on the Microsoft Cryptographic API (CRAPi [sic]) cryptographic providers in any way. Developers can distribute to their clients by simply copying a single file into the correct directory. For those users who do want ActiveX capability so they can call it from an ASP page, there is an ActiveX Interface.
Linux Version: There is also a beta Linux Version
with a static library which you are free to test and use on your own Linux system.
We created the static library on a Fedora Core 1 system and we've tested it on other Red Hat and Ubuntu systems without problems.
If it compiles OK and the detailed tests run without error then we are pretty confident that it will work for you.
There are three editions available. All have identical functions.
Please test the CryptoSys API before purchasing using either the Personal or Server Trial edition.
All editions include the full manual and test functions in Visual Basic, C, VB.NET and C#. The Server and Developer Editions include an ActiveX interface which can be called from ASP pages and other COM applications. The source code for the ActiveX and DotNet Class Library DLLs is included.
The install program and the product functions have been tested on W95, W98, NT4, W2K and XP systems. The functions have been tested using Visual Basic 6, Microsoft Office VBA (97 and 2003), Microsoft .NET Framework 2.0, Microsoft Visual C++ versions 5, 6, 7, 8 and 9, and Borland C++Builder version 5.5.
Both the Personal and Server Editions have the same core cryptographic functions except the ActiveX interface does not work with the Personal Edition. The Personal Edition is for use on a stand-alone personal computer. It does not expire but has a pop-up when it is first used. The Server Edition is designed for use on both a server in an IIS/ASP environment or on a stand-alone or networked computer. Either edition may be used for evaluating the licensed Developer Edition, which works in any environment.
Hint: If for some reason you are having problems getting the Personal Edition to work, try installing the Server Edition instead.
See Using CryptoSys API with Microsoft Excel for an example of how to call a function in CryptoSys API from an Excel spreadsheet.
The functions in CryptoSys API can be called from a Delphi program in the same way you would call Win32 API functions. You need to provide a function statement with the correct parameters and types, and an external reference to 'diCryptoSys.dll'.
Sebastian Jäschke provided this simple interface to Delphi
showing how to call the SHA2_FileHexHash function to generate the SHA-256 digest of a file.
Humberto Souza has provided a Delphi program showing how to encrypt and decrypt
using the BLF_HexMode function together with
conversions to and from base64 and hex encoding for strings.
Humberto's full code and executable is in Delphi_example1.1.zip (216 kB)
(we have not tested this code). Last updated 2008-09-18.
The core product can be accessed directly using the classic Visual Basic, VBA, C and C++ programming languages. There are interfaces included in the installation download for .NET (C# and VB.NET) and ActiveX/COM. Browse the on-line .NET help manual. A beta Linux version is also available.
Hint: If you are considering writing an interface to CryptoSys API,
please note that the DLL is a simple Win32 DLL not an ActiveX one,
and that only 32-bit signed integers (LONG) and ANSI strings (LPSTR) are used throughout.
You call the functions in the same way you call Win32 API functions like GetUserName.
Refer to the sections of the manual on
Return Values
and
Type Conversions.
See above.
Jeff Luther has produced an interface using Team Developer (TD v1.5). See Jeff's Code Samples and scroll down to find CRYPTOGRAPHIC SAMPLES.
Users have sent in interfaces to the API's sister product CryptoSys PKI in PowerBuilder, the D programming language, Stony Brook Iso Modula-2 and PowerBASIC. Although not directly created for the CryptoSys API, those interfaces should give you enough hints on how to create an interface in your language. See Extra Interfaces.
Check the integrity of your CryptoSys API software.
Please refer to our brief introductions to Using Keys in Cryptography and Using Padding in Encryption.
No. For public key cryptography, see our CryptoSys PKI Toolkit.
The CryptoSys Blowfish and CryptoSys Hash products have been withdrawn. All functions in both products are available in CryptoSys API, which is fully supported and has interfaces for C# and VB.NET programmers. Existing licence holders can still Download a Developer Version of CryptoSys Blowfish and Download a Developer Version of CryptoSys Hash.
CryptoSys Encode version 2.0 released 17 August 2003 is still available for free.
For free cryptographic code written by David Ireland, including Blowfish in Visual Basic, a full set of multiple-precision arithmetic routines written in ANSI C, base64 encoding; CRC-16, CRC-24 and CRC-32 routines; the MySecret Blowfish utility, and more, visit DI Management's Cryptography Software Code Page.
