Encrypt the Chef User’s Private Key
Chef Server uses public key cryptography to authenticate API requests. This requires the client to sign a hash of requests using a valid private key. In this example, we’ll use KMS to encrypt a copy of our Chef Server certificate (with its associated private key) and then decrypt it on the fly with the Lambda function as needed. This allows us to safely store our Chef Server credentials at rest in encrypted form without the risk of unauthorized users discovering the decryption key needed to access the credentials.

Create a customer master key (CMK) in KMS and note the keyId that is automatically generated. Make sure the IAM user you want to use for encrypted the Chef Server certificate and the Lambda role created in the previous section are added as a key users in KMS. Your IAM user needs kms.encrypt permissions to encrypt the certificate, while your Lambda user (via an IAM role) needs kms.decrypt permissions at runtime to access the certificate.
