Advantages of DES over other algorithms:
- DES has been around a long time (since 1978) and has been studied to death. Even now no real weaknesses have been found: the most efficient attack is still brute force. Of course the 56-bit key size is a disadvantage - see below.
- DES is an official United States Government standard; the Government is required to re-certifyDES every five years and ask it be replaced if necessary. DES has been re-certified in 1983, 1987, 1992. (What happens this year?)
- DES is also an ANSI and ISO standard - anybody can learn the details and implement it.
- Since DES was designed to run on 1978 hardware, it is fast in hardware and relatively fast in software.
Disadvantages of DES:
- The 56-bit key size is the biggest defect of DES. Chips to perform one million of DES encrypt or decrypt operations a second are available (in 1993). A $1 million DES cracking machine can search the entire keyspace in about 7 hours.
- Hardware implementations of DES are very fast; DES was not designed for software and hence runs relatively slowly.

What are some uses for encryption algorithms?
Encryption algorithms are typically used in computer communications. An encryption algorithm provides a secure transfer for data by encrypting it before presenting at another computer or elsewhere.
Can you explain how to securely hash data for encryption purposes?
To securely hash data for encryption, you can use algorithms like SHA-256 or bcrypt. These algorithms take the input data and produce a fixed-length hash value. This hash value can be used as a key for encryption. It is important to use a strong and secure hashing algorithm to protect the data from being easily decrypted.
