I have already published a lot of AutoIt UDF about algorithm, but all of them only support 32 bits or so called X86 system. Recently I got a computer with Windows 7 64 bits, so I finally added X64 support to most of my old projects. Besides, I also added some new. For example, some compression algorithm and SHA3 Candidates.   Following are the algorithms list:   Checksum CRC16 CRC32 ADLER32 Compression FastLZ LZF LZMA LZMAT MiniL
