| DECRYPTION STATION — PUZZLE #13287 |
+==============================================================================+
CIPHER TYPE: CRYPTO1
SECURITY LEVEL: 7/7
STATUS: [ACTIVE — AWAITING DECRYPTION]
MISSION BRIEFING
----------------
48-bit LFSR state: 0xDEADBEEF1234. Feedback polynomial: 0x3D0000000001. Run the LFSR for 48 clock cycles and convert output to ASCII letters.
INTERCEPTED DATA
----------------
> poly:
0x3D0000000001
> state:
0xDEADBEEF1234
> hint:
Crypto-1 uses a 48-bit LFSR. For each cycle: compute parity of tapped bits (where poly has 1s), shift right by 1, insert feedback at bit 47. First 48 output bits → 6 bytes → mod 26 → letters.
> answer format:
lowercase letters, no spaces or punctuation (6 chars from LFSR keystream)
