Abstract: Validation of digital documents is one of the important issues in the era of information and communication technology, given the increasing use of digital documents in all aspects. Another thing that is important in a digital document is a matter of safety and capacity of the file of documents. Data compression as a science exists to be a solution to the data requires a large storage capacity; the process of data compression is to reduce the number of bits used to store and transmit data. Compression of data covering a wide range of compression techniques implemented in software and hardware with a lot of advantages. One alternative to maintain data security is by using cryptographic algorithms that implement DES (Data Encryption Standard). DES algorithm is a symmetric cryptographic algorithm that uses the same key for encryption and decryption. DES algorithm works on 64 bit data blocks and uses a key length of 56 bits. The processes contained in the DES algorithm include an internal key generation, initial permutation, enciphering, and the final permutation.
