Improve encrypting ocx

I need improve OCX file with encryption algorithms. Just fixing binary file access read/write and some other light bug fixes.

## Deliverables

I need the following bugs fixed in the attached OCX: 1. each algorithm (module) used in that ocx reads THE WHOLE file into the memory and then encode/decode it. Its a wrong way, as it is limited to computer's RAM and program returns error on a large files. This should be fixed, OCX should read and write files (encode/decode) partially (may be by blocks), allowing unlimited file sizes. 2. coder must improve (suggest ways) to improve speed of the encryption/decryption algorithms, as they all very slowly. 3. each change in the code should be commented and I can lookup all changes using "Find" 4. When you're done: please check that encoding and decoding functions works fine, even on a large files, accepting only correct pass-key.
