Function Documentation

ComputeCRC32()

uint32_t Aws::Crt::Checksum::ComputeCRC32 ( ByteCursor  input, uint32_t  previousCRC32 = 0  )

noexcept

The entry point function to perform a CRC32 (Ethernet, gzip) computation. Selects a suitable implementation based on hardware capabilities. Pass previousCRC32 if updating a running checksum.

ComputeCRC32C()

uint32_t Aws::Crt::Checksum::ComputeCRC32C ( ByteCursor  input, uint32_t  previousCRC32C = 0  )

noexcept

The entry point function to perform a Castagnoli CRC32c (iSCSI) computation. Selects a suitable implementation based on hardware capabilities. Pass previousCRC32C if updating a running checksum.

ComputeCRC64NVME()

uint64_t Aws::Crt::Checksum::ComputeCRC64NVME ( ByteCursor  input, uint64_t  previousCRC64NVME = 0  )

noexcept

The entry point function to perform a CRC64-NVME (a.k.a. CRC64-Rocksoft) computation. Selects a suitable implementation based on hardware capabilities. Pass previousCRC64NVME if updating a running checksum. There are many variants of CRC64 algorithms. This CRC64 variant is bit-reflected (based on the non bit-reflected polynomial 0xad93d23594c93659) and inverts the CRC input and output bits.
