Text Encryptor

Encrypt text with a classic Caesar cipher and a chosen shift.

Quick answer

Encrypt text with a classic Caesar cipher and a chosen shift.

How do I use the Text Encryptor?

  1. 1

    Paste your plain text.

  2. 2

    Choose the shift value.

  3. 3

    Copy the encrypted output.

What is the Text Encryptor?

The Text Encryptor applies a classic Caesar shift cipher to any message. Great for classroom demonstrations, puzzle creation and light obfuscation of harmless notes.

Who is the Text Encryptor for?

Teachers running crypto lessons, puzzle designers, hobbyists exploring ciphers, and students learning basic cryptography.

Why use the Text Encryptor?

  • Any shift value.
  • Preserves case and non-letters.
  • Instant preview.
  • Deterministic output.
  • Runs offline.

When should I use the Text Encryptor?

  • Classroom crypto lessons.
  • Escape-room puzzles.
  • Treasure-hunt clues.
  • Icebreaker games.
  • Light obfuscation of harmless notes.

Is the Text Encryptor safe and private?

Yes. This tool runs entirely inside your browser - your text is never uploaded, stored on our servers or shared with third parties. You can even disconnect from the internet after the page loads and it will keep working. That makes it safe for confidential notes, drafts, private messages and unpublished work.

How do I get the best results from the Text Encryptor?

  • Caesar is a toy cipher - never rely on it for real security.
  • Shift 13 gives you classic ROT13.
  • Combine with Text Decryptor to test reversibility.
  • For real encryption, use dedicated cryptography tools.

Frequently asked questions

Is Caesar cipher secure?

No - Caesar is trivially breakable. Use it for puzzles, teaching or light obfuscation only, never for real secrets.

What shift should I use?

Any integer works. The classic ROT13 uses shift 13; classroom examples often use 3.

Does it handle non-Latin letters?

Only A–Z and a–z are shifted. Digits, punctuation and other scripts pass through.

Is my text uploaded?

No - encryption runs locally.
