NAME
    gcloud alpha kms mac-sign - sign a user input file using a MAC key version

SYNOPSIS
    gcloud alpha kms mac-sign --input-file=INPUT_FILE
        --signature-file=SIGNATURE_FILE [--key=KEY] [--keyring=KEYRING]
        [--location=LOCATION] [--skip-integrity-verification]
        [--version=VERSION] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) Creates a digital signature of the input file using the provided
    MAC signing key version and saves the base64 encoded signature.

    The required flag signature-file indicates the path to store signature.

    By default, the command performs integrity verification on data sent to and
    received from Cloud KMS. Use --skip-integrity-verification to disable
    integrity verification.

EXAMPLES
    The following command will read the file '/tmp/my/file.to.sign', and sign
    it using the symmetric MAC CryptoKey dont-panic Version 3, and save the
    signature in base64 format to '/tmp/my/signature'.

        $ gcloud alpha kms mac-sign --location=us-central1 \
            --keyring=hitchhiker --key=dont-panic --version=3 \
            --input-file=/tmp/my/file.to.sign \
            --signature-file=/tmp/my/signature

    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud kms mac-sign
