Text Encryptor

Encrypt and decrypt text with a key

About Text Encryptor

Text Encryptor obfuscates text with a password-based XOR cipher and Base64 encoding, entirely in your browser. It's a quick way to make text unreadable to a casual viewer without the password, though it is not a substitute for strong encryption standards like AES when protecting truly sensitive information.

How to use Text Encryptor

  1. 1Enter or paste the text you want to encrypt.
  2. 2Type a secret key — this becomes your password, so remember it exactly.
  3. 3Click "Encrypt" to scramble the text, or "Decrypt" to reverse a previously encrypted message with the same key.
  4. 4Copy the result from the output field.

Frequently Asked Questions

Is Text Encryptor completely free to use?

Yes, it's 100% free with no signup and no limits on how much text you can process.

How secure is this encryption?

It uses a password-based XOR cipher followed by Base64 encoding — not AES or any "military-grade" standard. It's a fast way to obfuscate text so it isn't readable at a glance, but it shouldn't be relied on to protect highly sensitive or confidential information.

What if I forget my key?

The text can't be recovered without the exact original key — there's no password recovery option.

Is my data uploaded anywhere?

No, encryption and decryption both happen entirely in your browser — your text and key are never sent to a server.

Tips & Tricks

  • ✓Use a key you'll remember exactly — even one character off will produce garbled, unrecoverable output when decrypting.
  • ✓This tool suits casual privacy (keeping a note unreadable at a glance), not protecting data against a determined attacker.
  • ✓Always keep a copy of your original text, since there's no way to verify the key before you've already encrypted or decrypted.
  • ✓AES and Caesar Cipher options aren't available — the encrypt/decrypt buttons both use the same XOR + Base64 method regardless of what you type.
