So I’m trying to encrypt my {s:tr,i:ng} but for some reason the one i get has some weird characters at the end and the cookies I’m trying to use does nothing…

Any advice?

The user name and cookie is available, can someone point me in the right directions.

Hi, I am getting this error during decryption. Help?
"ERROR: All of the responses were identical.

Double check the Block Size and try again."

You may be using the command in a wrong way.

Any tips for solving this challenge? I just solved ‘Grammar’. Is it similar to that?

Just figured this out. Awesome challenge.

i use tools to get the key of the cookie,but error.

ERROR: All of the responses were identical.

Double check the Block Size and try again.

any idea or Hint ?

Pls PM me/

I’ve decrypted the cookie. However when I encrypt the parameters it doesn’t do anything. I’ve tried many different variations, but now I am quite confused at what I could be doing wrong. I have the tool, I have the {“u”:“s”,“r”:“a”} plaintext. And ideas on what I could be missing?

I am on the same spot. tried to change the other part of the cookie also to True. but no result

I’m also stuck here.

Got it. Was an error on my part.

Can anyone help me? i’ve tried the bitflipping with burpsuite grepping the username on profile, but the problem is that i don’t get error and so i’m not able to enumerate the users to find others.
Can anyone give me a hint or PM me?

Thank you for your big help and “wasting” your valuable time to help me with a problem.
I do appreciate that! Thx.

I really enjoyed this challenge. It did have some tricky parts.
Ok to DM me if anyone hits a wall and needs a sanity check / guidance.
