Base32 Encoder / Decoder
Encode and decode text using Base32 (RFC 4648) — used in TOTP authenticators and DNS labels.

-
Caesar Cipher
Encode and decode text with the classical Caesar shift cipher using a custom shift amount (1–25).
Open tool →
-
Atbash Cipher
Encode and decode text with the Atbash cipher — mirror the alphabet so A↔Z, B↔Y, C↔X, etc.
