Symmetric encryption algorithm online tool

This tool provides encryption and decryption functions for many mainstream symmetric encryption algorithms, includingAES、DES、RC4、Rabbit andTripleDes， Support user-defined key, real-time verification of encryption and decryption results.

Main Functions

- Multi-algorithm support： Cover common symmetric encryption algorithms to meet the needs of different scenarios.
- ** Custom key**: users can enter any password as the encryption key to ensure data security.
- ** Instant Feedback**: Encryption or decryption results are displayed in real time for easy debugging and verification.
- ** No Installation Required**: Browser-based operation, no need to download software or plug-ins.

How to use

1. **Select Algorithm**: Select the desired encryption algorithm (e.g., AES-256) from the drop-down menu.
2. **Enter key**: Fill in the custom password (must meet the requirements of the algorithm).
3. **Submit data**: Enter the text to be encrypted or decrypted in the input box.
4. **Get Result**: Click "Encrypt" or "Decrypt" button, the result will be displayed immediately.

Scenarios

- ** Development test**: quickly verify the implementation of the encryption algorithm.
- ** Teaching Demonstration**: Visualise the working principle of symmetric encryption.
- ** Data Protection**: Temporarily encrypt sensitive information to ensure transmission security. Tip: Please keep the key properly, after the loss of data will not be able to recover! This tool only provides algorithm testing, does not store any user input information.
