This is a Burp extension for signing AWS requests with SigV4. Signature Version 4 is a process to add authentication information to AWS HTTP requests. More information can be found here

SigV4 uses a timestamp to give signatures a limited lifetime. When using tools like Burp repeater, this plugin will automatically compute a new signature with the current timestamp. You can also repeat requests using different AWS credentials.

Features:

• Credentials can be imported from a file or environment variables.
• Automatically select a profile based on the key id in the request.
• Resend requests with different credentials.
• Context menu item for copying s3 presigned URLs.
• Assume a role by providing a role ARN and optional external ID.
