Flag format — inctfj{flag_here}
Flag Format: inctfj{...}
Given a hex encoded ciphertext. Using one of the online hex-decoders, I decoded the ciphertext. Unfortunately it was not the end but was just a beginning only😇…On decoding got Base64 encoded text. Using an online Base64 decoder decrypted it…But that was also not the end. At some point I thought I was in the wrong direction. But the challenge title, made me feel I was right.
Hint to identify diff. encodings:
- Hexadecimal codes only use the digits 0–9 and letters A-F or a-f
- Base64 is easy to recognize. It consists of letters (about 50% uppercase and 50% lowercase), as well as numbers, and often equal-characters (=) at the end.
After series of Hex and Base64 decodings, I got the 🏁…..
