Client-side SSL

Convert SSL certificate from CRT format to PEM

openssl x509 -in server.crt -out server.der -outform DER
openssl x509 -in server.der -inform DER -out server.pem -outform PEM

Associating an in-game player with a Discord account

Why

• Want to have a Discord user be able to enter commands to a bot and have actions impact their account in-game or not.
• Want an in-game user to be able to enter commands and have a bot "carry those over" to Discord
• Want to have the bot be able to access players' information

Examples:

1. Discord user enters /mystats and bot replies with info about their money, score, etc, and whether they're currently connected or not.
2. Player "John12" enters command '!dsay hello discord' and bot sends that message on a discord channel
