DES Encryption/Decryption
Encrypt or decrypt text and files using the Data Encryption Standard (DES) algorithm. Secure your data with this classic symmetric-key cipher. All processing in browser.
Information
Our free online DES (Data Encryption Standard) tool allows you to encrypt and decrypt text or files using this widely known symmetric-key algorithm. DES was highly influential in the advancement of modern cryptography. While AES is now recommended for new applications, DES and its variant Triple DES (3DES) are still relevant for legacy systems and understanding cryptographic principles. This tool performs all encryption and decryption operations directly in your browser, ensuring that your data never leaves your device, providing complete privacy and security. Choose between DES and 3DES, select operation modes like ECB and CBC, and manage your keys securely for robust data protection.
How to Use
- Select encryption or decryption mode
- Enter or generate an encryption key
- Enter the text to process and click the encrypt/decrypt button
Note: DES is considered a legacy encryption standard and is not recommended for new applications. For new applications, please use AES encryption. This tool is for educational purposes and legacy system compatibility only.
