Webster family names as cipher key material (DRUSILLA, WEBSTER, WILLIAM)
Webster family names as Vigenere/Beaufort key material (DRUSILLA, WEBSTER, WILLIAM, etc.)
In plain English: Webster family names as Vigenere/Beaufort key material (DRUSILLA, WEBSTER, WILLIAM, etc.) — using a key derived from a thematic word or phrase. Every possible combination was tested (288 configurations) — none produced a valid solution.
This approach is ruled out within the tested scope.
NOISE
Tier 2
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.
- Configs Tested
- 288
- Best Score
- 5 / 24 known letters matched · no better than random guessing (random guess would score: 0.0)

Scope Limitations
This elimination does not rule out:
- Only tests Webster family name variants as periodic keys. Does not test other biographical key sources.
Assumptions
- Periodic key derived from names
- Vigenere/Beaufort/VB
- Direct positional correspondence
