   What is a Data Encryption Standard?

   • Data encryption standard (DES) was the US government's first encryption algorithm approved for widespread use. It is an older system that uses one 56-bit key to generate a block of 64-bit cypher text from a block of 64-bit plain text. The development of DES led to the rise of the cryptography business.

   How does DES encrypt and decrypt a message?

   • DES uses the same key to encrypt and decrypt a message, so both the sender and the receiver must know and use the same private key. DES was once the go-to, symmetric key algorithm for the encryption of electronic data, but it has been superseded by the more secure Advanced Encryption Standard ( AES) algorithm.

   How strong is encryption?

   • Encryption strength is directly tied to key size, and 56-bit key lengths have become too small relative to the processing power of modern computers. So, in 1997, NIST announced an initiative to choose a successor to DES and undertook a five-year evaluation process of 15 encryption algorithms.
