Aes ctr openssl submodule

[Knogle]

Ahoy, OpenSSL integrated through git submodule :) Stically linked during build.

Thanks, I'll check this out shortly. I'm finalising stfp transfers for ShredOS, as soon as I'm done with that I'll review this PR. What did you get nwipe's binary size down too in the end?

[Knogle]

Currently we are on 3.7M (still w.o. compression) , we can crop this down even further, but in order to do so i have to check with the OpenSSL IRC, what else we can remove during build, there are a few things that can be stripped still. If you say this is OK so i can invest some little more time and do some further optimizations on this PR.

Yes, I'd like it stripped down to the absolute minimum, I'd hate to go from 1MB to nearly 4MB just to add one prng. However once it's size has been optimised as far as it will go, I'll test it in ShredOS on some older systems to make sure there's no obvious performance issues.

I do hate bloat though, so the smaller you can make it the better. 😁

I think we won't reach something similar to the dynamic library approach with around 1M, but maybe we can get a little closer :) My current nwipe binary is around 2.3M now. I think i can still get it a little lighter.

So the best i can currently do is 2.3M, if we remove instrinsics and assembler instructions it goes down to 1.5M but at cost of speed (AES get's very slow, as it doesn't use CPU acceleration anymore). Another option, have the libcrypto.soinstead in the directory, so a shared library.

Or, using upx, to put it down to 1.1M.

@PartialVolume This one as a second option. 432k binary, and the libcrypto.so (symlinked to libcrypto.so.3 etc.) in the same folder as shared library.

Closed due to dynamic approach.
