Signs data using a CryptoKeyVersion with CryptoKey.purpose MAC, producing a tag that can be verified by another source with the same key.

post/v1/{+name}:macSign

Path parameters

namestring required

Required. The resource name of the CryptoKeyVersion to use for signing.

Request body

dataCrc32cstring int64

Optional. An optional CRC32C checksum of the MacSignRequest.data. If specified, KeyManagementService will verify the integrity of the received MacSignRequest.data using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(MacSignRequest.data) is equal to MacSignRequest.data_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.

datastring byte

Required. The data to sign. The MAC tag is computed over this data field based on the specific algorithm.
