To perform this step, you must acquire the AWS Clean Rooms collaboration ID and the shared secret key. For more information, see the Prerequisites.
In the following example, we run the encryption on ads.csv, using the schema
that we created called ads.json.
To encrypt data
-
Store the shared secret key for the collaboration in Step 6: Store the shared secret key in an environment variable.
-
From the command line, enter the following command.
java -jar c3r-cli.jar encrypt<name of input .csv file>--schema=<name of schema .json file>--id=<collaboration id>--output=<name of output.csv file><optional flags> -
For
<name of input .csv file>, enter the name of the input .csv file. -
For
schema=, enter the name of the .json encryption schema file. -
For
id=, enter the collaboration ID. -
For
output=, enter the name of the output file (for example,ads-output.csv). -
Include any of the command line flags described in Cryptographic computing parameters and Optional flags in Cryptographic Computing for Clean Rooms.
-
Run the command.
In the example for ads.csv, we run the following command.
java -jar c3r-cli.jar encrypt ads.csv
--schema=ads.json
--id=123e4567-e89b-42d3-a456-556642440000
--output=ads-output.csv
In the example for sales.csv, we run the following command.
java -jar c3r-cli.jar encrypt sales.csv
--schema=sales.json
--id=123e4567-e89b-42d3-a456-556642440000
Note
In this example, we don't specify an output file name
(--output=). As a result, the
default output file name sales-output.csvname-of-file.out.csv was generated.
You are now ready to verify the encrypted data.
