## Overview

The Text Encryptor/Decryptor is a versatile utility designed to transform plain text into various encoded formats and revert them back, supporting algorithms like Base64, ROT13, Caesar Cipher, and more.

## Inputs

- **Text** (textarea): Enter text to encrypt or decrypt...
- **Operation** (select)
- **Algorithm** (select)
- **Key (for Caesar Cipher)** (number): Enter shift value (1-25)

## When to use

- Obfuscating sensitive information for basic data protection.
- Encoding text strings for web development or data transmission.
- Solving puzzles or decoding simple cipher-based messages.

## How it works

- Enter your source text into the input area.
- Select your preferred operation (Encrypt or Decrypt).
- Choose an algorithm from the list, such as Base64 or Morse Code.
- Provide a shift key if using the Caesar Cipher, then view the transformed output.

## Use cases

- Quickly encoding configuration strings into Base64 for API headers.
- Creating simple text-based puzzles using ROT13 or Caesar ciphers.
- Converting text to binary or Morse code for educational demonstrations.

## Frequently asked questions

### Is this tool secure for sensitive passwords?

This tool is intended for basic text transformation and obfuscation, not for high-level cryptographic security.

### What algorithms are supported?

The tool supports Base64, ROT13, Caesar Cipher, Reverse Text, Morse Code, and Binary.

### Do I need to provide a key for all algorithms?

No, a key is only required when using the Caesar Cipher to define the shift value.

### Can I reverse the encryption?

Yes, simply select the 'Decrypt' operation and choose the same algorithm used for encryption.

### Is my data stored on your servers?

No, all text processing is performed locally in your browser for your privacy.
