Really interesting. I had to sign invoices using a private key so that the local financial authorities could decrypt / verify the data using our public key. I used openssl for this: from key generation to message signing. What I found out is that using openssl inside php results in an encryption that could not be validated by the financial authorities, but inserting the same code inside an artisan command solved the issue. To this day I cannot figure out why it is the case. I took me 3 days to come up with a solution.


Therefore, an example would be greatly apreciated. If you'd like I can show you my implementation :)
