SecretPayload

A secret payload resource in the Secret Manager API. This contains the sensitive secret payload that is associated with a SecretVersion.

JSON representation 
{
  "data": string,
  "dataCrc32c": string
}
Fields
data

string (bytes format)

The secret data. Must be no larger than 64KiB.

A base64-encoded string.
dataCrc32c

string (int64 format)

Optional. If specified, SecretManagerService will verify the integrity of the received data on SecretManagerService.AddSecretVersion calls using the crc32c checksum and store it to include in future SecretManagerService.AccessSecretVersion responses. If a checksum is not provided in the SecretManagerService.AddSecretVersion request, the SecretManagerService will generate and store one for you.

The CRC32C value is encoded as a Int64 for compatibility, and can be safely downconverted to uint32 in languages that support this type. https://cloud.google.com/apis/design/design_patterns#integer_types
