- Future plan would be not to use OpenSSL directly, but to go via PlatformCrypto or something like it which could provide platform specific RSA functionality if it exists
- Also contains some compensation code for platforms that are still stuck on an older version of OpenSSL (everything except windows)
- On platforms that use OpenSSL < 1.1.1, register a locking callback so we can provide mutexes and stop it crashing horribly when the same RSA key is used concurrently on different threads
Changed default key size in the CryptoKeys plugin to 4096 bits.

- CryptoKeys plugin can now be told how many bits to use for keys. Defaults to 2048 as a happy medium between security and performance
- After creating the OpenSSL RSA key, use the exp/mod values directly rather than recomputing from primes
- Added RSA.h with some TBigInt based helpers for RSA keys
- Added FPakSignatureFile to wrap the contents of the pak .sig file, including determining that it is of a new format that supports versioning. Wraps the encryption and decryption of he master table hash
- Changed pak master signature hash from crc to SHA1
- Modified access to executable embedded public key data so that it is just an array of bytes. Will allow custom key sizes in the future.

Reuse previously decompressed buffer where possible to avoid repeatedly deserialising and decompressing the same block when serializing data < compressed block size.

- Added memory mapped IO concept to the engine
- Implemented and tested on Windows and IOS
- Not in use by anything yet, however, as the use cases are narrow and special (bulk data that does not need massaging after load - so it can be swapped out and back in silently by OS)
