Options for wodCrypt
Lightweight component that provides strong encryption for your applications. It provides supports for most common crypto algorithms, such as
for symmetric encryption and decryption,
for making and verifying signatures, and
for creating hashes.
Working with Blobs
wodCrypt works with Blobs - Binary Large Objects (it doesn't have to be big, of course) when it comes to data manipulation. Blob is our object that can read files, string variables and bytes array, and provide the same as their output. Even more, it can present the information in BASE64 and HEX encoded data - in case your environment just doesn't like to work with binary data.
Besides working in regular way - without random padding and internal wrapping, wodCrypt can work in Optimized mode as well. In that case most probably no other encryption tool will be able to access (directly) your encrypted data - because wodCrypt will add specific information to it - such as size of blob. This way when decryption is done, you will get exactly the same plaintext as it was before encryption. In regular way, wodCrypt has to look after block sizes for each protocol, key sizes etc.. so any empty space needs to be filled with zeros. It's not smart way to protect the data - but it's necessary to make encrypted text open to other decryption tools, for you to get the results as expected.
Licensing - royalty free
wodCrypt is royalty free - once you make your application, you can distribute binary versions of wodCrypt free of charge. Licenses are purchased only for design-time development, one license per each developer on the project - and that's all!
Besides ActiveX version (which can be used even in FoxPro), wodCrypt has COM object as well, which can be used from many environments, such as VB, VC, Delphi, VBS, ASP etc..
