• Guru: A Faster Way To Sign A JWT

  July 21, 2025 Chris Ringer

  In my prior article, which you can read here, I discussed using the OpenSSL tool to asymmetrically sign a JWT. I like OpenSSL because it’s an open source solution available on many platforms and easy to use. But the decision to use OpenSSL should be coupled with the performance level expectations (the PLA) for your project.

  For instance, how many tokens will you need to create in a given interval? Will your newly minted tokens expire 24 hours from now or in 5 minutes? In my case currently, only about 5 JWTs are needed per day so …

• IBM Bolsters Db2 for i With Tech Refreshes

  October 23, 2024 Alex Woodie

  IBM is delivering a handful of new database capabilities with the latest batch of Technology Refreshes for IBM i 7.5 and 7.4, including new function to create Universally Unique Identifiers (UUIDs), new capabilities for the security data mart, and various enhancements to SQL-based IBM i Services.

  A UUID is a random 36-character, 128-bit alphanumeric string that can be used to identify something, such as a row or table in a database, with near certainty that the identifier is unique, has never been used before, and will never be used again.

  The UUID system was first implemented by the Open Software …

• Guru: Web Concepts For The RPG Developer, Part 3

  July 22, 2024 Chris Ringer

  Greetings everyone. Articles part one and two were both an introduction on how to build components in an HTTP request. In part three, we will begin to connect the dots and discuss how to asymmetrically sign a simple string. If you ever need to send a secure HTTP request to a government agency or financial institution, you likely will authenticate with a signed token. So, here we go!

  Base64 Take Two

  In part one, the SQL scalar function BASE64_ENCODE embedded in RPG converted a string to base64. This technique will cover most use cases, but what if you need …

• Guru: Parsing JSON That Has Spaces In The Key

  July 8, 2024 Mike Larsen

  One of my favorite tasks is working with APIs. I’ve worked with many APIs over the years, and some introduce unique challenges that must be overcome. Recently, I worked on a project where I was to consume a REST API that provided a JSON payload. While that seems straight forward, I quickly discovered a challenge.

  The JSON payload had keys that have spaces in them (Figure 1). That may be considered bad practice, but I still needed to figure out how I could parse it correctly. Having never seen JSON like this before, I started with a Google search. I …
