DES Encryption Tool

Encrypt and decrypt text using the DES (Data Encryption Standard) algorithm. All processing is done in your browser - no data is sent to any server.

Instructions

  • Enter your text in the input field on the left
  • Provide an 8-character encryption key
  • Select the encryption mode (ECB or CBC)
  • Click Encrypt or Decrypt to process the text
  • Use the Copy button to copy the result to your clipboard

Note: ECB (Electronic Codebook) is simpler but less secure, while CBC (Cipher Block Chaining) provides better security.
