full disk encryption software development
I'm interested in full disk encryption for professional and personal reasons. I Tried a bunch of software but none of them ever meet all of my criteria witch are:
-very strong encryption (AES 256 is enough of course)
-Transparency, no need of a fancy interface. I just want to enter my key before booting my OS's...
-simple and effective: I really don't need features like key changing or keylog protection
-Multi-Boot compatible witch is the most important thing for me and Multi-drive compatible
Based on my new experience in that area after trying Diskcrypt plus pack, truecrypt, PGP encryption, Diskcryptor and a few other, I came with an idea: Since I know exactly what i'm looking for, why can't I program it myself? Of course I'm talking about a very tiny piece of software but I'm not particularly an expert in that matter so I'd like to ask some advices but first let me explain what I had in mind...
What I want is some sort of pre-boot authentication by password, the perfect thing for me would be that the password needed to gain access to the computer is actually the encryption key. I have a very good memory and memorize a 256 sequence of random characters is nothing I'm afraid of. When the user has eventually succeeded the pre-boot authentication, my special program will then chain boot on a bootloader like GRUB for instance, and therefor everything will look at the user's eyes like the system is absolutely not encrypted.
So, what I concretely need is a small program that can encrypt my hard drives, block access of the whole system at boot-level, require an encryption key and then use that key to decrypt my hard drives in real time (independently of the OS running ideally, although I don't know if it is possible on a software basis) and then chainboot on a bootloader like GRUB.
The problem is I don't really know how to start... Do I need to make a bootable partition on my system drive to force the computer to boot on it and run my program that way (that seems quite complicated) or could a small software stored on the MBR like GRUB actually do all this?
I would also like to add a few things:
This is a most serious project. Even if I'm not an expert, I'm ready to learn and/or study hard
If all this eventually tends to become usable and functional, I'm clearly willing to publish it as an open-source project or a freeware.
Thank you all in advance for your help.
