NAME
    gcloud alpha kms raw-decrypt - decrypt a ciphertext file using a raw key

SYNOPSIS
    gcloud alpha kms raw-decrypt --ciphertext-file=CIPHERTEXT_FILE
        --plaintext-file=PLAINTEXT_FILE --version=VERSION
        [--additional-authenticated-data-file=ADDITIONAL_AUTHENTICATED_DATA_FILE]
        [--initialization-vector-file=INITIALIZATION_VECTOR_FILE] [--key=KEY]
        [--keyring=KEYRING] [--location=LOCATION]
        [--skip-integrity-verification] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) gcloud alpha kms raw-decrypt decrypts the given ciphertext file
    using the given CryptoKey containing a raw key and writes the result to the
    named plaintext file. The ciphertext file must not be larger than 64KiB.

    The supported algorithms are: AES-128-GCM, AES-256-GCM, AES-128-CBC,
    AES-256-CBC, AES-128-CTR, and AES-256-CTR.

    AES-GCM provides authentication which means that it accepts additional
    authenticated data (AAD). So, the flag --additional-authenticated-data-file
    is only valid with AES-128-GCM and AES-256-GCM algorithms. If AAD is
    provided during encryption, it must be provided during decryption too. The
    file must not be larger than 64KiB.

    If --plaintext-file or --additional-authenticated-data-file or
    --initialization-vector-file is set to '-', that file is read from stdin.
    Similarly, if --ciphertext-file is set to '-', the ciphertext is written to
    stdout.

    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 reads and decrypts the file path/to/input/ciphertext.
    The file will be decrypted using the CryptoKey KEYNAME containing a raw
    key, from the KeyRing KEYRING in the global location. It uses the
    additional authenticated data file path/to/input/aad (only valid with the
    AES-GCM algorithms) and the initialization vector file path/to/input/iv.
    The resulting plaintext will be written to path/to/output/plaintext.

        $ gcloud alpha kms raw-decrypt --key=KEYNAME --keyring=KEYRING \
            --location=global --ciphertext-file=path/to/input/ciphertext \
            --additional-authenticated-data-file=path/to/input/aad \
            --initialization-vector-file=path/to/input/iv \
            --plaintext-file=path/to/output/plaintext

REQUIRED FLAGS
     --ciphertext-file=CIPHERTEXT_FILE
        File path of the ciphertext file to decrypt.

     --plaintext-file=PLAINTEXT_FILE
        File path of the plaintext file to store the decrypted data.

     --version=VERSION
        Version to use for decryption.

OPTIONAL FLAGS
     --additional-authenticated-data-file=ADDITIONAL_AUTHENTICATED_DATA_FILE
        File path to the optional file containing the additional authenticated
        data.

     --initialization-vector-file=INITIALIZATION_VECTOR_FILE
        File path to the optional file containing the initialization vector for
        decryption.

     --key=KEY
        The (raw) key to use for decryption.

     --keyring=KEYRING
        Key ring of the key.

     --location=LOCATION
        Location of the keyring.

     --skip-integrity-verification
        Skip integrity verification on request and response API fields.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

NOTES
    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 raw-decrypt

        $ gcloud beta kms raw-decrypt
