These instructions don't create the private key - which is needed for LTI to work. #1861

This is still an issue 2 years later. That comment is very misleading. |

I spend a good amount of time trying to debug an issue where the only error message was "Private key is needed" (see below)
It turned out the LTI keys that were generated using the code in the comment was creating public keys (which the command does indicate) - but it's not the private key needed for LTI to work.
I ended up using Canvas::Security::RSAKeyPair.new.to_jwk.to_json which worked and stopped the below error. I'd recommend updating the comment in this file to reflect this as I couldn't find any other documentation on this.
`Private key is needed.
