Date-derived key '1986' (Egypt trip year) as var_beaufort
Date-derived key '1986' (Egypt trip year) as var_beaufort
In plain English: Date-derived key '1986' (Egypt trip year) as var_beaufort — using a key derived from a date (like when Kryptos was built).
This approach is ruled out within the tested scope.
NOISE
How to read this record
- Verdict – NOISE (no better than random guessing), INTERESTING (slightly above random, almost certainly coincidence), SIGNAL (statistically unusual, warrants investigation), or FULL MATCH (all 24 known letters correct).
- Confidence Tier – Tier 1 = mathematical proof (permanent). Tier 2 = every possibility tested. Tier 3 = partially tested. Tier 4 = not yet tested.
- Configs Tested – How many different key/parameter combinations were tried.
- Best Score – How many of the 24 known plaintext letters the best attempt matched (out of 24).
- Keystream Consistency (Bean) – Whether the key values at different positions are mathematically consistent with each other.
- Scope Limitations – What this elimination does not rule out.
