Hey Robert, I’ve been sorting through some forgotten encryption rituals from the 1970s and I suspect there’s a hidden mathematical pattern that could tighten modern key schedules. Thought you might enjoy a deep dive into the old logs.

Sure thing, Robert. Grab a pen and follow these steps: 1. Open the archived tape deck file—it's in a 4-bit nibble format, each line is a 64‑byte block. 2. Convert each block to a 8×8 binary matrix; the first 8 bits go in the first row, the next 8 in the second, and so on. 3. Compute the XOR of every adjacent pair of rows; this will give you a new 8×8 matrix that represents the key‑schedule delta. 4. Look for a pattern of constant submatrices—if you find a 4×4 block that repeats every 16 rows, that’s your hidden algebraic structure. 5. Verify the structure by multiplying the block by a random 4×4 identity matrix and seeing if the output matches the original delta block. Let me know what you see, and we’ll test whether the old 70s tricks still hold.
