awscrt.checksums

awscrt.checksums.crc32(input: bytes, previous_crc32: int = 0) → int

Perform a CRC32 (Ethernet, gzip) computation.

If continuing to update a running CRC, pass its value into previous_crc32. Returns an unsigned 32-bit integer.

awscrt.checksums.crc32c(input: bytes, previous_crc32c: int = 0) → int

Perform a Castagnoli CRC32c (iSCSI) computation. If continuing to update a running CRC, pass its value into previous_crc32c. Returns an unsigned 32-bit integer.

awscrt.checksums.crc64nvme(input: bytes, previous_crc64nvme: int = 0) → int

Perform a CRC64 NVME computation. If continuing to update a running CRC, pass its value into previous_crc64nvme. Returns an unsigned 64-bit integer.
