Perform a length extension attack on SHA256. Can someone help me find what I'm doing wrong?
I have performed the attack using this hash_extender and got the correct signature, but I'm getting the wrong answer when I try to perform the attack by modifying the original algorithm.

YouTube: Google has found a way to break Invidious
A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.
I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

PicoCTF 2024- CanYouSee
❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

CyberChef from GCHQ: The Cyber Swiss Army Knife
It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.
The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

Lets try this again. Got a code for you to break.
I think this can be deciphered using CyberChef...
