How to use Boto3 to generate a random password in AWS Secret Manager
Problem Statement: Use boto3 library in Python to generate a random password in AWS Secret Manager
Approach/Algorithm to solve this problem
Step 1: Import boto3 and botocore exceptions to handle exceptions.
Step 2: There are no parameters here.
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_random_password and pass the parameter as per the desired complexity.
Step 6: It returns a random password.
Step 7: Handle the generic exception if something went wrong while generating the random password.
Example Code
Use the following code to generate random password −
import boto3
from botocore.exceptions import ClientError
def generate_random_password():
session = boto3.session.Session()
s3_client = session.client('secretmanager')
try:
response = s3_client.get_random_password(PasswordLength=18,
ExcludeCharacters="",
ExcludeNumbers=False,
ExcludePunctuation=True,
ExcludeUppercase=False,
ExcludeLowercase = False,
IncludeSpace=False,
RequireEachIncludedType=True
)
return response
except ClientError as e:
raise Exception("boto3 client error in generate_random_password: " + e.__str__())
except Exception as e:
raise Exception("Unexpected error in generate_random_password: " + e.__str__())
a = generate_random_password()
print(a["RandomPassword"])Output
