(Hopefully) Daily Coding Challenge #1

Because it's becoming a trend to make quizzes and challenges and stuff. Also because it might help you become better at coding. So my first challenge is to make a text to Base64 converter. If you don't know what Base64 is, go to Wikipedia or read my short explanation in the answer below. I already made one, here it is: https://code.sololearn.com/cuSmXYEVZIbg/?ref=app For increased difficulty, make it able to convert a string to and from Base64, having the user specify whether it should de- or encrypt.

I prefer challenges that I can do in my head... But I'll have to read up on this and I'll probably make one in C# Later on... maybe... idk

So basically you take the ascii values of the symbols in a string, convert them to bytes, put them togeter to a big list, split them into 6-digit binary numbers, if last number is too short add 0s to it, then convert those numbers back to decimal and turn them into symbols of the Base64 alphabet: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/ where A = 0, B = 1 etc. Put those together. If the length of the original string % 3 isn't 0, add as many = to the end of the output string as there are missing characters to make the length be dividable by 3 in the original string. Yes I know shitty explanation

@Jafca this is a coding challenge, not a thinking challenge ;)
