Tiến hành Decode Base64

Hmm, gì đây nhỉ, có cả kí tự k đọc được và kí tự đọc được, mà bài này lại là bài warn up là ở dạng dễ
Mình nghĩ rằng có thể nó là xor , cơ mà khi thử cả xortool lần xortay thì nhận ra rằng tầm bậy r
Vậy có thể là ascii ceasar quay vòng vòng nhỉ?
Thử viết script để test xem sao?


ok vẫn fail :)) cay rồi
How about Caesar thẳng cái base64 -_-  và cuối cùng tại ROT13, ta nhận được flag

Report - Misc ( 200 + 0 ) Mr. Belford sucks, is he hiding something.... Download:  http://dl.ctf.rocks/Report.tar.gz We are given a PDF file, at first i though maybe they hide some image or hidden text inside the pdf, so i use this site to extract   But wow, the are neither image nor font ,  nothing but text and metadata, cool  :D  So i was googling to see if the anyway to hide data in PDF We know that hidden data can be embeded in  But in SHA2017 CTF, i have solved something encrypted with AES , to recover, we must know how the PDF Structure to get key, so i think maybe the data is embeded in the OBJ section like  and below is the hidden data that we need to find.  So I used binwalk to extract data in pdf file ( fore some reason i cant use any pdf tool in my ubuntu, still working on fixing lol ) , then check the obj section ( in .zlib ) as u can see, we know that the prefix "SECT" in hex are : 53 45 43 5...

1. Crypt100 : Stackoverflow I had some issues implementing strong encryption, luckily I was able to find a nice example on  stackoverflow  that showed me how to do it. Challenge:  stackoverflow.tgz File contains: - Script At first, when we check the given site above, we know that this pdf was encrypted with AES-CTR mode, and more interesting, we can see that they reuse the Counter -> that make AES-CTR vulnarable to Known-Plaintext attack crypto = AES.new(os.urandom(32), AES.MODE_CTR, counter=lambda: secret) with secret = os.urandom(16) Okay, let take look at the AES-CTR , let see the reason why they are vulnerable to Known-Plaintext attack: 107.50 KB Normally Counter must be UNIQUE , so that the keystream will be different every step. It is more secured than reused , it will make AES-CTR encryption become:  E(m[i]) = message[i] ^ keystream = cipher[i] and when we know the plaintext message[i] and the cipher[i] , we will get t...
