wodCrypt ActiveX Control - FileBlob Object
FileBlob Object
    
 
Description

FileBlob Class


Remarks

The FileBlob object stores any type and size of data into the file of your choice (through the Filename property).

You should use FileBlob when you have large amounts of data to be encrypted/decrypted. The definition of 'large amounts' depends on your application - it can even be a few hundred megabytes. wodCrypt will never load the full file at once - it will read/write to it as needed, using smaller chunks.

In addition to the following properties and methods, a FileBlob can be also referenced through its Blob interface. For the Blob interface specification, please look here.
