Interface ObjectChecksumsOrBuilder (2.58.1)

CRC32C digest of the object data. Computed by the Cloud Storage service for all written objects. If set in a WriteObjectRequest, service will validate that the stored object matches this checksum.

optional fixed32 crc32c = 1;

Optional. 128 bit MD5 hash of the object data. For more information about using the MD5 hash, see https://cloud.google.com/storage/docs/hashes-etags#json-api. Not all objects will provide an MD5 hash. For example, composite objects provide only crc32c hashes. This value is equivalent to running cat object.txt | openssl md5 -binary
