Each license includes one year of free updates, and unlimited lifetime
technical support. Remember that each developer must have his own
design-time license.
General information
wodCrypt is a lightweight component that provides strong encryption for
your applications. It provides support for most common crypto algorithms,
such as
AES
DES, TripleDES
Blowfish
Cast
RC2
RC4
RC5
UNIX crypt command
for symmetric encryption and decryption,
RSA
DSA
for making and verifying signatures, and
MD5
SHA1
for creating hashes.
Working with Blobs
For perfroming 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 two variants of
it: MemBlob and
FileBlob - you can use whichever of these
is more appropriate to your application.
MS Authenticode signatures
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.
Optimized code
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.
Licensing - royalty free
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..
Additional notes
* 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.
