DECRYPT

PDFRSS

You can use the DECRYPT transform to decrypt inside of DataBrew. Your data can also be decrypted outside of DataBrew with the AWS Encryption SDK. If the provided KMS key ARN does not match what was used to encrypt the column, the decrypt operation fails. For more information on the AWS Encryption SDK, see What is the AWS Encryption SDK in the AWS Encryption SDK Developer Guide.

Parameters

• sourceColumns – An array of existing columns.

• kmsKeyArn – The key ARN of the AWS Key Management Service key to use to decrypt the source columns. For more information on the key ARN, see Key ARN in the AWS Key Management Service Developer Guide.

{
   "sourceColumns": ["phonenumber"],
   "kmsKeyArn": "arn:aws:kms:us-east-1:012345678901:key/<kms-key-id>"
}

When working in the interactive experience, in addition to the project’s role, the console user must have permission to kms:GenerateDataKey and kms:Decrypt on the provided KMS key.

Sample policy:

  "Version": "2012-10-17",
  "Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "kms:GenerateDataKey",
            "kms:Decrypt"
        ],
        "Resource": [
            "arn:aws:kms:us-east-1:012345678901:key/<kms-key-id>"
