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
