Presigned URL in S3

 Presigned URLS

By default, all Amazon S3 objects are private, only the object owner has permission to access them. However, the object owner may share objects with others by creating a presigned URL. A presigned URL uses security credentials to grant time-limited permission to download objects. The URL can be entered in a browser or used by a program to download the object. The credentials used by the presigned URL are those of the AWS user who generated the URL.

 

You can use the Amazon S3 console to generate a presigned URL for sharing an object by following these steps. When using the console the maximum expiration time for a presigned URL is 12 hours from the time of creation.

 

1. To generate a presigned URL by using the Amazon S3 console

Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/.

 

2. In the left navigation pane, choose Buckets.

 

3. In the Buckets list, choose the name of the bucket that contains the object that you want a presigned URL for.

 

4. In the Objects list, select the object that you want to create a presigned URL for.

 

5. On the Object actions menu, choose Share with a presigned URL.

 

6. Specify how long you want the presigned URL to be valid.

 

7. Choose Create presigned URL.

 

8. When a confirmation appears, the URL is automatically copied to your clipboard. You will see a button to copy the presigned URL if you need to copy it again.
