Description

CRCTable_DEPRECATED

DEPRECATED These tables and functions are deprecated because they're using tables and implementations which give values different from what a user of a typical CRC32 algorithm might expect.lookup table with precalculated CRC values

CRCTablesSB8

Lookup table with precalculated CRC values - slicing by 8 implementation

CRCTablesSB8_DEPRECATED

Lookup table with precalculated CRC values - slicing by 8 implementation
