cryptography+FAT12 Help
Posted: Mon Mar 04, 2002 12:00 am
I like to develop a Crytographic FAT12 system
(real mode,Turbo C,dos)
Its simple,
Encryption (while creating a file)
* get a key from user (when he logs in)
* encrypt the files content
* write to disk
Decrytion (while reading a file)
* get key from user (when he logs in)
* read file content from disk
* decrypt the file content
I think there's a lot of disadvg. in it. Live it.
I wrote the code for reading a file with errors,
I feel hard to create a file.
If you have any codes for FAT12 file create/read
in C(dos). plz share with me.
