v1.1.0

Added 1-level recursively functionality so that a folder can be provided and all VALID files within that folder are encrypted/decrypted accordingly.

Known vulnerability that causes a seg fault. Only resultant errors are related to "address sanitisation". Potentially worth looking into in the future?

v1.0.0

Initial Release. Currently on tested on Linux as OpenSSL building (for static linking) requires troubleshooting on Windows.
