10 sourcesMy company just released a JWT library for java that supports Ed25519[0]. Any idea how I can submit that to the ianix list?

In A Vulnerability in LibsodiumFusionauth-JWT v6.0.0 Released
1 points · Open discussionI had not used gemini before, so spent a fair bit of time yak shaving to get access to the right APIs and set up my Google project. (I have an OpenAPI key but it wasn't clear how to use that service.)
I changed it to use this line:
api_key=os.getenv("GEMINI_API_KEY", "your-api_key")
instead of the default project/location option.
and I changed it to use a different model:
model = os.getenv("GEMINI_MODEL", "gemini-2.5-pro-preview-03-25")
I used the preview model because I got rate limited and the error message suggested it.
I used this on a few projects from my employer:
- https://github.com/prime-framework/prime-mvc a largish open source MVC java framework my company uses. I'm not overly familiar with this, though I've read a lot of code written in this framework.
- https://github.com/FusionAuth/fusionauth-quickstart-ruby-on-...
Read the rest
a smaller example application I reviewed and am quite familiar with.
- https://github.com/fusionauth/fusionauth-jwt a JWT java library that I've used but not contributed to.
Overall thoughts:
Lots of exclamation points.
Thorough overview, including of some things that were not application specific (rails routing).
Great analogies. Seems to lean on them pretty heavily.
Didn't see any inaccuracies in the tutorials I reviewed.
Pretty amazing overall!
I work for the company behind this library but not on it.
RSA is by far the most common algo needed for integrations, so I can't imagine not supporting it.
We have an open issue about supporting EDDSA (of which Ed25519 is the most likely implementation) https://github.com/FusionAuth/fusionauth-jwt/issues/13 but it hasn't gotten shipped due to other priorities.
In A simple to use Java 8 JWT LibraryThis doesn't depend on BouncyCastle AFAICT, by default it uses javax.crypto but you can change it for a BouncyCastle security provider.

Another data point. Our open source JWT library[0] and Java client library[1] both target Java 8 because that is widely used.
