Solution

Here is a breakthrough, showing step by step what you had to do in order to solve the crypto-puzzle.
The two given hints were:
base64
http://www.xup.in/dl,60841354/breakit.rar/

and
Caesar Encryption

User @anduweb found out that the password to decrypt the .rar file was given in the header image. The letters LOXYZYZKVOYJJUTK is Caeser-shifted and decrypted is the following: firststepisdone. This however is not the password to unlock the rar file. Notice that I had a spelling mistake in the headline. P and Y are switched and have a number each, 1 and 2. The encrypted word has also the numbers 1 and 2, which lead to the conclusion so switch the letters here as well. Bingo now it works!

@waldfee finally was able to solve the puzzle and found out that inside the .rar file was a picture. This picture contained the pastebin logo and a code. The code was part of the URL to the pastebin doc. Inside this pastebin doc was a base64 encoded passphrase U3RlZW1mZXN0MnJvY2tzIQ==. She successfully decrypted the word and got the right solution! steemfest2rocks!
