Hi Everyone,
I am developing a minifilter driver which encrypt and decrypt files on fly. When i save txt file i receive a sector aligned buffer in my prewrite function with nocache io flag set. Basically iopb->Parameters.Write.Length gives size of buffer not the size of content in that and hence i am encrypting whole buffer not just my content. Next challenge is i am not able to save the extra bytes, generated during encryption, to disk.
How can make this work?
Thanks in advance.
