gcloud beta kms raw-decrypt

NAME
gcloud beta kms raw-decrypt - decrypt a ciphertext file using a raw key
SYNOPSIS
gcloud beta 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
(BETA) gcloud beta 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.
