CRC32C Calculator के बारे में

CRC32C uses the Castagnoli polynomial (0x82F63B78 reflected), which provides better error-detection properties than standard CRC32 and has direct hardware acceleration on Intel/AMD (SSE4.2) and ARM CPUs. It is the checksum standard for Google Cloud Storage, AWS S3, Ceph, and SCTP.
