Welcome!
Welcome to all who will attempt this challenge so the goal is to decrypt the message first.
The message

f6A=LJu9ii0ep6HyfiB4LJuZDi0eM6HyfiB1LJugKl0eMx9yfxkHLJu9Hi0eM6HyfyBQQfTG

Post your result below when you think you got it.

Solution will be posted at 9:30 pm EST if no one solves it.

Good luck!

Hints
I will post three hints over the course of 3 hours to make it easier.

Hint 1: 64+64=
Hint 2: It has 3 layers of encryption figure them out.

Im assuming this is a troll/beg for attention because there is nothing hidden in the OP

Sorry I forgot to paste the code I accidentally hit the post button before I was done.

it's a base64 string but decoding it gives gibberish. considering the fact that the = is in the middle of the text when it should be at the very end I'm going to go out on a limb and say the characters are rearranged somehow, but the fact that you've given us no information on how means that it would be nearly impossible to decode.

I've got one for you guys to decode.

What the hell
What bit size is this?
Also Isnt PGP for SSL Certificates or is that RSA

256 I believe. SSL uses RSA encryption.

how'd you get so computer literate?
can you teach me some stuff pls

Ipquarx probably knows more about encryption than I do. My post was a joke because PGP encryption is nearly impossible to crack. You need a 256 bit public key to decrypt it which means there are roughly 11579209000000000000000000000 00000000000000000000000000000 00000000000000000000 possible combinations (2^256), on every which possibility you have to run expensive calculations to decrypt the message.

The second level of encryption is base 64 so you got part of it right.

Hint: 64+64 =
