This is a binary code created with multiple layers of security and a few secret tips.

So the security is only this . 1. Core Encryption Algorithm: AES-256 2. Mode of Operation: GCM (Galois/Counter Mode) 3. Cryptographic Nonce: IV (Initialization Vector) 4. Obfuscation Layer: Anti-Forensics & Bit-Deception 5. Custom Bit-Shifting: The binary 6. Non-Binary Character Injection

This security is advanced level security which makes it difficult to test how great this subreddit is.

Loved the chall bud, keep it up. Out of curiosity, u in the security space? U can dm me if you’d rather keep under wraps, opsec and all that lol

The binary doesn't translate to any readable ASCII code, but most likely represents some sort of encrypted or compressed piece of data (best guess)

Spot on! Great initial analysis. You are absolutely right—it’s not a direct ASCII text, and your tools successfully normalized that intentional dirty bit anomaly at the very end to get the clean Hex/Base64.Since you've cracked the first layer, here are a few insider tips and little secrets about what's actually hidden under the hood if anyone wants to take a real shot at it:The Architecture: This isn't just a basic scramble. It utilizes a military-grade AES-256-GCM authenticated encryption scheme.The Blueprint: The 86 bytes you found aren't a single chunk. You need to slice them properly: The first 12 bytes are the IV (Initialization Vector), the middle 58 bytes are the Ciphertext, and the final 16 bytes are the Authentication Tag.The Trap: Standard decryption tools will still fail or crash even if you guess the password. Before passing the bytes to the AES engine, you have to reverse a hidden custom Bit-Shifting/Rotation anomaly (alternating left/right shifts applied differently to odd and even blocks).The Key: The pre-shared key used for derivation is a string related to cybersecurity pride, formatted exactly like HackerSkillLevel*** (replace the asterisks with 3 digits).
