Introduction to DES Encryption and Decryption Tool

This tool provides online encryption and decryption functions based on DES (Data Encryption Standard) algorithm, supports 64-bit key DES as a classic symmetric encryption algorithm, widely used in early network security, suitable for understanding the basic principles of encryption.

Core Functions

- Bidirectional encryption/decryption： Input plaintext or ciphertext, get the corresponding result with one click.
- Customizable key： Support user input 8-byte (64-bit) key to enhance data security.
- Real-time response： Fast processing of text content, results are displayed instantly without delay.
- Strong compatibility： Adapt to a variety of devices, no need to install plug-ins, browser direct use.

Usage Scenarios

- Development Test： Verify the compatibility and effectiveness of the DES algorithm in your project.
- Data Protection： Temporarily encrypt sensitive information for transmission or storage.
- Teaching Demonstration： Help students understand how symmetric encryption algorithms work.

How it works: 1.

1. Select Encryption or decryption mode;
2. Input the text to be processed;
3. Fill in the 8-character key (if not, use the default key). 4;
4. Click the "Execute" button, the result will be displayed in the output box.
The result will be displayed in the output box.： If you need to save the encrypted data for a long time, please backup the key properly, lost key will not be able to decrypt! This tool only provides algorithm testing, it is not recommended to use in high security scenarios. If you need higher level of protection, please combine with other encryption methods.
