Atbash tips

↔️

Atbash maps each letter to its mirror image in the alphabet: A↔Z, B↔Y, C↔X, etc. It's completely self-inverse like ROT13.

πŸ“œ

Atbash was used in the Hebrew Bible. The word "Sheshach" in Jeremiah 25:26 is an Atbash encoding of "Babel" (Babylon) β€” likely used to avoid political scrutiny.

πŸ’‘

"HELLO" in Atbash = "SVOOL". The vowels and consonants mix, making it look genuinely different from the original.

🧩

Atbash puzzles appear in the Da Vinci Code and similar cryptographic fiction. If you see a message with no obvious pattern, try Atbash.
