Amazon Web Services (AWS) Simple Storage Solution (S3) has upgraded its application programming interface (API) to support HTTPS. This upgrade involved a redesign of the authentication process at AWS. The authentication process now involves authenticating the user and verifying the canonical request made to AWS S3.
Morten Braten and Jason Straub have published and supported tools related to AWS S3 and Oracle PL/SQL. These tools, located within the Alexandria Library, do not support the new AWS4 signature and do not support HTTPS.
During the recent months, I have researched the AWS interface and written an updated package. I have hosted these tools at my github . I think with solid collaboration and greater testing from our Oracle and APEX community we can get this package solid enough to be included in the library.
At Storm Petrel, we use AWS S3 to augment the database for the storage of documents in our various document management tools. We keep an original in a BLOB and a modified copy at S3. We have wanted to make sure that ALL communication between the users and our infrastructure is 100% encrypted. With the link to AWS S3 travelling via HTTPS, we can stand behind this statement.
Initially, AWS S3 was all hosted from the Northern Virginia region. S3 is now hosted in 15 regions. Some of these regions require HTTPS and some require the AWS4 signature. It seems that AWS will want to depreciate the HTTP interface in time. Best to stay ahead of the demand!
This was well out of my comfort zone. In 2015, we wrote an interface to MailChimp. In 2016, interfaces to FEMA and to Nexmo for SMS and multifactor authentication. The AWS S3 stuff was tough!!!!
What is next?
I focused on getting the feature we use in place. AWS S3 has a huge number of features. This package does not even have all of the features that Morten put in to the original effort. So, testing and continued development is what is next.
I can’t do it alone. The foundation is here. The authentication stuff and HTTPS stuff works. Now to add the other bits that S3 has to offer, or that we need.
Please direct yourself to the Github site for more information about the package, and to get the packages. At that site you will find:
