Security Warning
- DES uses a 56-bit effective key length, which is considered insecure for modern applications
- For sensitive data, use AES encryption instead
- This tool is for educational purposes and should not be used for highly sensitive data
- Never share your encryption keys with unauthorized parties
About DES
- Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data
- Developed in the 1970s and published as a standard by NIST
- Uses a 56-bit key (plus 8 parity bits, for a total of 64 bits)
- Operates on 64-bit blocks of data
- DES is now considered obsolete for most cryptographic applications due to its short key length
- Triple DES (3DES) was developed as a more secure alternative
