When generating VAPID keys getting an error

[DomantasDielektrik]

When trying to generate VAPID keys on the terminal, I got an error: "Unable to create the key".

Using:
Laravel: 8.x, PHP: 7.4
Any suggestions?

Do you find any solution?

Do you find any solution?

I tested this on several Laravel projects. One was written on Laravel 8, another written on Laravel 5.7. Only on the Laravel 5.7 project, I manage to generate VAPID keys.

You need to install the OpenSSL to resolved this problem

i already enable OpenSSL in xampp extension but still not working. i am using windows 10.

Maybe you can try this way:
https://stackoverflow.com/questions/17272809/openssl-pkey-export-and-cannot-get-key-from-parameter-1/18869750#18869750
on step9, I used "c:\xampp\apache\conf\openssl.cnf".
My Laravel is 8.7x and windows 10,and keep ";extension=openssl" on php.ini.
Hope it can help you.

Even with open ssl, laravel version 8 gives an error while creating vapid key. There is no error in laravel 5, but I did not find a valid solution for laravel 8.

[BienvenidoBoriko]

for laravel 9 worked instaling opnssl https://slproweb.com/products/Win32OpenSSL.html

If you're on Windows, the easiest way is to install openssl with scoop like this:

scoop install openssl

Then the VAPID keys will be created successfully:

php artisan webpush:vapid
