How to use Boto3 to get the secret keys saved as plain text from AWS Secret Manager

Problem Statement: Use boto3 library in Python to get secret keys from AWS Secret Manager

Approach/Algorithm to solve this problem

  • Step 1: Import boto3 and botocore exceptions to handle exceptions.

  • Step 2: secret_stored_location is the required parameter. It is a place where secrets are saved.

  • Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.

  • Step 4: Create an AWS client for secretmanager.

  • Step 5: Call get_secret_value and pass the secret_stored_location as SecretId.

  • Step 6: It returns all the secrets that are present without encryption in the given location.

  • Step 7: Handle the generic exception if something went wrong while retrieving values.

Example Code

Use the following code to get the plain text secret from AWS Secret Manager −

import boto3
from botocore.exceptions import ClientError

def get_secret_details(secret_stored_location):
   session = boto3.session.Session()
   s3_client = session.client('secretmanager')
   try:
   response = s3_client.get_secret_value(SecretId=secret_stored_location)
   return response
   except ClientError as e:
      raise Exception("boto3 client error in get_secret_details: " + e.__str__())
   except Exception as e:
      raise Exception("Unexpected error in get_secret_details: " + e.__str__())

a = get_secret_details('/secrets/aws')
print(a['SecretString'])

Output

{"aws.user":"SERVICE_USER","aws.accesskey":"I**************"}
