See http:https://en.wikipedia.org/wiki/Cyclic_redundancy_check for more information.

This package is deprecated. Please use the CRC32 implementation in any of the following libraries:

• CRC32.jl -- interface to the optimized CRC-32 implementation in Zlib
• CRC.jl -- written in pure Julia, supports many CRC variants
• CRC32c standard library -- highly optimized implementation of the closely related CRC-32c checksum

That being said, this package demonstrates a minimal, simple implementation of CRC32 in pure Julia code, which may be of educational interest.

julia> using CRC32

julia> crc = crc32("hello")
0x3610a686

julia> crc32(", world", crc)
0xffab723a

julia> crc32("hello, world")
0xffab723a
