The cryptographic hash value for an object is a form of fingerprint. HCP uses a cryptographic hash algorithm to calculate this value from the object data. HCP then uses this hash value to check that object data remains unchanged.

You can view this value, but you cannot change it.

With HTTP, cryptographic hash values are returned by the X-HCP-Hash response header. With the WebDAV, CIFS, and NFS protocols, you view this value in the hash.txt metafile.

HCP does not generate cryptographic hash values for multipart objects. Therefore, the X-HCP-Hash header is not returned for these objects.
