Generating publick and private keys

How to Generate Private and Public keys for JWT Authentication

Generating the private and public keys yourself can be challenging so am going to use this website: http://travistidwell.com/jsencrypt/demo/ to easily generate them.

On the website, you can use either 4096 bits or 2046 bits as the key size but am going to use 4096 bits. After selecting the key size, click on the “Generate New Key” button to generate the keys.

Now let’s visit this website:https://www.base64encode.org/ to encode both keys in base64. Copy each of the keys and paste it into the “Encode to Base64 format” Textarea then click on the “Encode” button. Ensure you encode the private key first before encoding the public key. Ensure your change the destination to ASCII and choose CRLF(Windows) as the line separator.

After each encoding copy the encoded key and paste it into the .env file respectively.
