class FSHA1

	Type	Name	Description
		FSHA1 ()	Constructor and Destructor.

	Type	Name	Description
		~FSHA1 ()

Type	Name	Description
void	Final ()	Finalize hash and report.
FSHAHash	Finalize ()	Finalize hash and return it.
bool	GetFileSHAHash ( const TCHAR* Pathname, uint8 Hash, bool bIsFullPackageHash )	Gets the stored SHA hash from the platform, if it exists.
void	GetHash ( uint8* puDest )	Report functions: as pre-formatted and raw data.
FSHAHash	HashBuffer ( const void* Data, uint64 DataSize )	Calculate the hash on a single block and return it
void	HashBuffer ( const void* Data, uint64 DataSize, uint8* OutHash )	Calculate the hash on a single block and return it
void	HMACBuffer ( const void* Key, uint32 KeySize, const void* Data, uint64 DataSize, uint8* OutHash )	Generate the HMAC (Hash-based Message Authentication Code) for a block of data.
void	InitializeFileHashesFromBuffer ( uint8* Buffer, uint64 BufferSize, bool bDuplicateKeyMemory )	Shared hashes.sha reading code (each platform gets a buffer to the data, then passes it to this function for processing)
void	Reset ()
void	Update ( const uint8* data, uint64 len )	Update the hash value.
void	UpdateWithString ( const TCHAR* data, uint32 len )	Update the hash value with string.
