* CRC64: cyclic redundancy check, 64-bits
|
|
*
|
|
* In order to validate that artifacts are not being corrupted over the wire, this redundancy check allows us to
|
|
* validate that there was no corruption during transmission. The implementation here is based on Go's hash/crc64 pkg,
|
|
* but without the slicing-by-8 optimization: https://cs.opensource.google/go/go/+/master:src/hash/crc64/crc64.go
|
|
*
|
|
* This implementation uses a pregenerated table based on 0x9A6C9329AC4BC9B5 as the polynomial, the same polynomial that
|
|
* is used for Azure Storage: https://github.com/Azure/azure-storage-net/blob/cbe605f9faa01bfc3003d75fc5a16b2eaccfe102/Lib/Common/Core/Util/Crc64.cs#L27
