Project status?

[nbubna]

Is this project still functional?

I have a spring preauth filter that is trying to use BasicLTIUtil.validateMessage(req,url,secret) to verify signatures from a LaunchPad LMS, and it only works occasionally. Same when i test it with other LTI-1p0 Tool Consumer emulators. Sometimes it succeeds, but more often i get invalid signature errors.

There's not much documentation, and i can't find any reason why this is wrong. I'm wondering if this is due to outdated dependencies in this project? Especially wondering about this one:

        <groupId>net.oauth.core</groupId>
        <artifactId>oauth-provider</artifactId>
        <version>20100527</version>

Help?

This project is mostly maintained by me in my free time, with generous help from others at times.

I'll need a bit more detail to help you through your issue.

Would you be able to provide a valid launch (a list of signed parameters + url) that the BasicLTIUtil .validateMessage method fails?

Is the invalid signature error the only error you see, or are there others?
