Input

DES Encryption Tool

Generate DES keys and run CBC, ECB, CFB, or OFB encryption and decryption flows.

  • DES is legacy-only and included for compatibility scenarios.
  • CBC, CFB, and OFB encryption generate an IV that you need for decrypting.
  • ECB mode has no IV but should be treated as educational only.
