🔐 Text Decoder

A simple web app designed for encrypting and decrypting short text messages using custom substitution rules.
This project was created as a personal challenge to strengthen my JavaScript logic and front-end design skills!

💡 How to Use

  1. Type your message
    Write lowercase and accent-free text in the input field.

  2. Encrypt or Decrypt
    Click Criptografar to encode your message.
    Click Descriptografar to decode it.

  3. Copy the Output
    The output will appear in the locked message box — click Copiar to copy the result!

🔎 Encryption Rules

CharacterReplacement
eenter
iimes

oober
uufat

Example:
Input: hello
Encrypted Output: henterllober

🎨 Project Overview

This project features:

  • A clean and responsive interface.
  • Smooth interaction between encryption, decryption, and clipboard actions.
  • Simple JavaScript logic focused on string manipulation.
  • Personalized layout and icons, including a custom logo designed for the Text Decoder identity.
