Atbash Cipher translation (English)

A=Z

B=Y

C=X

D=W

E=V

F=U

G=T

H=S

I=R

J=Q

K=P

L=O

M=N

O=L

P=K

Q=J

R=I

S=H

T=G

U=F

V=E

W=D

X=C

Y=B

Z=A

How it works: The Atbash cipher maps each letter to its reverse in the alphabet. Since it's symmetric, decryption uses the same process as encryption.

Privacy: Your data stays local and is never stored or transmitted.

How It Works

The Atbash cipher reverses the alphabet (A↔Z, B↔Y, etc.). Enter any text and the tool instantly applies the mirror substitution, transforming encrypted messages. It works both ways since Atbash is symmetrical.
