Text Encryptor / Decryptor (Conceptual)
Encrypt or decrypt text using a password. (Demo: uses simple XOR obfuscation, NOT for secure data)
Security Warning
This tool uses a simple XOR obfuscation method for demonstration purposes only. It is NOT cryptographically secure and should NOT be used for sensitive data. For real-world encryption, use the Web Crypto API or established libraries like CryptoJS.
Understanding Basic Text Encryption (XOR Cipher)
What is a XOR Cipher?
This tool uses a simple "XOR cipher" for demonstration. A XOR cipher is a type of "additive" cipher where each character in your text is combined with a character from the password using the XOR (exclusive OR) logical operation. The same process is used for both encryption and decryption.
The output is then Base64 encoded to ensure it's a printable string that can be easily shared.
Important Security Warning
This tool is for educational and demonstrative purposes ONLY. The XOR cipher used here is NOT cryptographically secure. It is a form of obfuscation, not true encryption.
- Do NOT use this tool for any sensitive data like passwords, credit card numbers, or private messages.
- It is easily broken with basic cryptanalysis, especially if the password (key) is short or reused.
- For real-world secure encryption, always use established, peer-reviewed algorithms like AES (Advanced Encryption Standard), which are available through browser APIs (Web Crypto API) or libraries like CryptoJS.
Why Is This Still a Useful Tool?
Even though it's not secure, this tool is great for:
- Learning: It provides a hands-on demonstration of a fundamental cryptographic concept.
- Simple Obfuscation: If you need to quickly hide some non-sensitive text from casual observation (e.g., in a public file or notes), it can be a quick and easy solution.
- Prototyping: Developers can use it as a placeholder for a real encryption module during early development stages.
