I want to write a minifilter driver to do block by block
encryption/decryptionn with chaining mode for encryption in units of data
blocks i.e.
I want to encrypt and decrypt whole data block and work in terms of data
blocks only. Is it possible in minifilter??
Or is there any other alternative?

If what you refer to as ‘block encryption’ means sector level encryption
and not file level encryption, then a volume or disk filter is the way
to go. Mini-filter’s will provide you a mechanism for encrypting on a
per file basis.

Exaclty…
Can you tell me from where to start to write “disk filter driver”?
Are there any examples of disk filter drivers?

You can always look through the DiskPerf example in the DDK. This gives
you a good starting point and can easily be made into either a disk or
volume class filter.
