In the continuation of the topic of cryptography, we show you the source code that encrypts the source text using the DES algorithm. By the way Data Encryption Standard (DES), intended for use in government and government agencies in the United States. DES encrypts 64-bit data blocks using a 56-bit key. Decryption in DES is an operation of reverse encryption and is performed by repeating encryption operations in the reverse order.
