Text Cipher Tool
Encode or decode text using a Caesar shift or XOR cipher, for fun and learning, not real security.
This is a fun, educational obfuscation tool — not real encryption. Don't use it to protect anything genuinely sensitive.

Overview
A playful way to encode and decode text using two classic, easy-to-understand cipher techniques — useful for puzzles, teaching basic cryptography concepts, or simple text obfuscation.
- Two distinct cipher methods in one tool
- Instant encode/decode as you type
- Clearly labeled as non-secure, so expectations are honest
How to use it
- 1Choose Caesar shift or XOR
- 2Enter your text and a shift amount or key
- 3Switch between Encode and Decode as needed
Frequently asked questions
Is this secure enough to protect sensitive information?
No. Both ciphers here are classic, easily-broken techniques meant for learning and casual puzzles — not for protecting anything genuinely sensitive. Use a real encryption tool for that.
What's the difference between the two methods?
A Caesar shift moves each letter a fixed number of places in the alphabet. XOR combines your text with a repeating key at the bit level, producing a hex string rather than readable text.
