wodCrypt is a lightweight component that provides strong encryption for your applications. It provides support for most common crypto algorithms, such as
For performing data manipulation, wodCrypt works with Blobs (Binary Large OBjectS - although they don't have to be Large!). The Blob is our object for reading and writing data - which means you can read and write string variables and bytes arrays. What's more, they can present the information in BASE64 and HEX encoded format if your environment doesn't like to work with binary data. A Blob is, by definition, an abstract object. We have created three variants of it: MemBlob, FileBlob and StreamBlob - you can use whichever of these is more appropriate to your application.
wodCrypt can create digital signatures based on Microsoft Authenticode technology. Assuming you have valid code signing certificate, you should just call SignEXE method to have your file digitally signed. No more Internet Explorer warnings will appear after you sign your files.
Besides working in accordance with cryptography standards (i.e. without random padding and internal wrapping), wodCrypt can also work in Optimized mode. In this case it is unlikely that other encryption tools will be able to (directly) access your encrypted data, because wodCrypt will add specific information to it such as the size of the Blob. Optimised mode ensures that after decryption you will get exactly the same plaintext as you had before encryption. When working to standards, wodCrypt has to look after block sizes, key sizes etc.. for each protocol, so any empty spaces need to be filled with zeros. It's not a smart way to protect the data - but it's necessary so that text that has been encrypted by wodCrypt remains accessible to other decryption tools and continues to give the expected results.
wodCrypt is royalty free - once you create your application you can distribute binary versions of wodCrypt free of charge. Licenses are purchased for design-time development only, one license for each developer on the project is required - and that's all!
Besides the ActiveX version (which can be used even in FoxPro), wodCrypt has a COM object as well, which can be used from many environments, such as VB, VC, Delphi, VBS, ASP etc..
* The wodKeys component is included in our setup package free of charge. It can be used for private key management - to Generate new keys, Load/Save keys, obtain public keys etc.. The helpfile can be found here.

Thank you for the great customer service ... I am really impressed with the wodSSH ActiveX control.
Thanks! We love your software and your great support!
You have been great as far as offering support is concerned and has been extremely responsive to both support requests and suggestions for product enhancements.
Your support is fantastic.
Just thought you'd like to know that my gateway app with your SMTP Server component held the line against a DDOS attack today...
...with the SFTP interface you produced, everything was so simple to understand, we were able to start coding almost immediately!
