utils

• aesSource : I implemented AES from source (and by lookup table). Wanted a better understanding of how it worked and stuff for when I perform Reverse Engineering steps.

• simpleFileEncryption : Makes is easy to use OpenSSL to encrypt files. Behaves like a copy command for a single file at a time. Works on both Linux and Windows.

• entropy : Two python utilities that were posted on the internet (not my own source) for determing entropy of a file (and a good indicator if a file is compressed or encrypted). I realized after making this, binwalk has a -E filename option that is great, graphs entropy and everything.

• FindFloats: Tool that will take raw hex, ignores extra non-hex characters, and dumps out all the possible values the hex could be converted to. For instance, the hex below contained a constant of pi in it
