This will allow the role to use the decrypt method for the specified encryption key:Īdd the ARN for your encryption key (the one you copied above) and select Add Statement to add the decrypt action on the specified encryption key to the newly created role policy. Select the AWS Key Management Service, and then select the Decrypt action. You can use the policy generator tool to create the policy: From the IAM console, select Roles and then the role you’re interested in: You now need to add the ARN for this encryption key to a policy that defines what the role used to execute the Lambda function can do. Select the encryption key and make a copy of the ARN that identifies it:

Once you’ve assigned the roles and defined the encryption key, you should be able to see it from the IAM Encryption Keys console listing: I avoided giving anyone administrative permissions:īut I did give usage permissions to the role I’d defined to execute my Lambda function: You then need to set various permissions for potential users of the encryption key. The is generated from the IAM console – select the Encyrption Keys element from the left hand sidebar, and then make sure you select the correct AWS region (that is, the region that the Lambda function is defined in) before creating the key:Ĭheck again that you’re in the correct region, and then give your key an alias (I used slackslashtest): The method is described here but I’ll walk you though it… To begin with, you’ll need to create an AWS encryption key.

In this post, I’ll describe how to to step up to the mark and use the encrypted token.Īlthough I tried to limit myself to free tier usage, an invoice from Amazon made me realise that there’s a cost associated with generating and subscribing to AWS encryption keys of $1 per month… In an earlier post, Implementing Slack Slash Commands Using Amazon Lambda Functions – Getting Started, I avoided the use of an encrypted Slack token to identify the provenance of an incoming request in favour of the plaintext version to try to simplify the “getting started with AWS Lambda functions” aspect of that recipe.
