Amazon S3 Utilities

Overview

The Amazon S3 Utilities Plug-in leverages the Amazon AWS Java API to connect with Amazon S3 to store and retrieve files.  

Key Features & Functionality

The following smart services are included:

  • Upload documents to AWS S3
  • Download documents from AWS S3
  • Create Folders in AWS S3
  • Delete documents from AWS S3

The plug-in also includes a function:

  • getPreSignedURLForS3 that generates a V4 pre signed url that expires after 5s. This allows for a short term access grant to a secured resource. It can be used in a WebAPI object to redirect a user from Appian to a resource on S3.

Amazon S3 Utilities supports the following Amazon S3 features:

 

Note:  The plug-in requires Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files when using client side encryption.

The Appian Secure Credential Store is leveraged for the credentials to integrate with Amazon S3. Before executing the plug-in, create an new secure credential store with the following 3 attributes.  These values are obtained from Amazon AWS IAM console.

  • accesskeyid: this is the access key id for connecting to AWS S3
  • accesskeysecret: this is the access key secret for connecting to AWS S3
  • kmscmkid: this attribute is only required if using AWS Client Side Encryption

  • Can we have parameter to set expiration time, instead of just defaulting it to 5Secs can we set it from Appian function. Reason is we are pulling the preassigned link and passing it to PDFTron plugin to display on Appian interface and the link is giving 403 if the document size is in MBs (Larger files). So please open the parameter as S3 bucket allows end users to set it up based on their need.

    I don't think the expiration time has anything to do with the issue, the 5s is just an expiration for the user/system to initiate the request - once started, the download will continue until completion.

    If we leave the expiration open then the generated link can be shared and document accessible to anyone.
