Text Encryption/Decryption

📖 Description

1. Why Do You Need a Text Encryption/Decryption Tool?

In digital communication, transmitting plaintext often carries risks:

• Social Privacy Protection: When sending information involving accounts, passwords, or private sentiments on platforms like WeChat or QQ, encrypting before sending prevents backend keyword scanning or shoulder surfing.
• Developer Data Debugging: Frontend developers need to quickly test if backend encryption/decryption interfaces are correct or simulate encrypting/decrypting data stored locally (e.g., in LocalStorage).
• Preventing Information Scraping: When posting contact details (phone numbers, email addresses) on forums or comment sections, using simple encryption can evade automatic scraping by crawler programs.
• Fun Interaction: Create "secret messages" that can only be deciphered by entering a specific "passphrase (key)", adding fun and a sense of ceremony to communication.

2. Core Features Explained

This site provides comprehensive encryption solutions ranging from "industrial-grade standards" to "basic encoding":

A. Industrial-Grade Symmetric Encryption (AES / DES / RC4)

• AES (Advanced Encryption Standard): Banking and military-grade standard, supporting 128, 192, and 256-bit encryption.
• Custom Secret Key: Users can set their own complex "decryption key". Only those with the same key can restore the original text.
• Padding & Mode Settings: Supports modes like CBC, ECB, meeting professional developers' debugging needs for Initialization Vectors (IV) and Padding methods.

B. Absolute Privacy: Browser-Side Local Computation

• Local Encryption/Decryption: All encryption and decryption algorithms are executed entirely within your browser's frontend.
• Zero-Upload Policy: Your plaintext and secret key are never uploaded to the server. Even the site's backend cannot access your private information. Security is equivalent to offline software.

3. Encryption/Decryption Effect Examples

4. Brief Operation Flow

Encryption Process:

1. Enter the text you want to hide in the "Original Text" box.
2. Select an algorithm (recommended: AES) and set a "Secret Key" known only to you.
3. Click "Encrypt".
4. Copy the generated ciphertext and send it to the recipient.

Decryption Process:

1. Paste the received ciphertext into the input box.
2. Enter the correct "Secret Key" provided by the sender.
3. Click "Decrypt".
4. The original text will be perfectly restored in the box below.
