- 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)

Workaround for UE-58013, though not a full fix. Requires setting bAllowNonUFSIniWhenCooked in the Target.cs and using a cooked build with pak files.

- Added support for compression plugins
- Removed the Custom compression concept, now using plugins properly
- Modified UnrealPak to use FNames, and allow for multiple compression methods (fallbacks on error or unavailability, etc)
- Added project settings for compression method selection for UnrealPak, and additional settings to be passed to UnrealPak (for instance, to control compression size/speed, etc)
- Deprecated a bunch of old function calls
- Improved pak file "old format" reading ability
- Brought over some changes from Fortnite for pak file encryption and memory savings
- Implemented a parallel compression pull request (#4129) to speed up pak file compression
