CAESAR CIPHER

Forty techniques. Scripture-centered investigations. Build the cipher, break the cipher, and learn why a shifted alphabet is not secure.

Cipher the Fox
CIPHER: A shifted alphabet can hide a message from someone who does not recognize the rule. It cannot protect it from someone who understands the weakness. Become that someone.

FIELD PRACTICE

Decrypt WUXWK with +3.

Decrypt ASVH with +7.

If A became D, what shift?

Brute force all 25 useful shifts.

SCRIPTURE INVESTIGATION

The cipher hides an ordinary reference. It does not create a secret biblical meaning.

SVDOP 119:105
Psalm 119:105
Your word is a lamp to my feet And a light to my path.

According to the verse, what is the lamp to the writer’s feet and light to his path?
