Can I use this for AWS S3 bucket policies?
Yes. The generated JSON uses the standard AWS Policy format (`Version: 2012-10-17`), which is fully compatible with IAM Users, Roles, and inline S3 Bucket Policies.

How AWS IAM Policy Generator Works
Users dynamically add Statement blocks, configuring the Effect, comma-separated Actions, and specific Resource ARNs. The tool instantly serializes this configuration into a valid, rigorously formatted IAM JSON policy payload ready to be pasted into the AWS Console or Terraform.

Practical Application & Code Integration
Use-Case Context
AWS Identity and Access Management (IAM) requires strict adherence to the Principle of Least Privilege. Hardcoding broad `s3:*` permissions is a massive security risk. Generating precise JSON policies (e.g., allowing `s3:GetObject` only on a specific bucket ARN) prevents catastrophic data breaches if an EC2 instance is compromised.
Least-Privilege S3 Policy
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": ["s3:PutObject"],
"Resource": "arn:aws:s3:::wtkpro-uploads-bucket/*"
}]

Common Questions About AWS IAM Policy Generator
How do I specify multiple actions?
Simply type them as a comma-separated list (e.g., `s3:GetObject, s3:ListBucket`). The generator will automatically format them into a valid JSON array.
