The Data Encryption Standard (DES) was introduced by the U.S.
National Institute of Standards and Technology (NIST) as a standard algorithm for encryption, and it was in widespread use during the 1980s and 1990s.
A Complete Guide to Understanding This Blockchain Concept
However, it did not prove to be very resistant to brute force attacks, due to advances in technology and cryptography research.
In July 1998, Electronic Frontier Foundation (EFF) broke DES using a special-purpose machine called EFF DES cracker (or Deep Crack).
This problem was addressed with the introduction of Triple DES (3DES), which proposed the use of a 168-bit key by means of three 56-bit keys and the same number of executions of the DES algorithm, thus making brute force attacks almost impossible.
However, other limitations, such as slow performance and 64-bit block size, were not desirable.
Why This Matters for Blockchain Technology
Understanding Data Encryption Standard is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
