Nowadays, it is often found a wide range of the securing information. The understanding that the author wants to design is about cryptography. Cryptography is the study of the security of data or information, commonly found in transferring data. One of them is the method of GOST, GOST is an abbreviation of "Gosudarstvennyi Standard" or "Government Standard." The algorithm is simple encryption algorithm which has some processes as many as 32 rounds and uses 64-bit block cipher with 256-bit key. GOST method also uses the S-Box 8 pieces of permanent and XOR operations and Rotate Left Shift. The author chose the GOST topic since the author wants to describe the understanding of the GOST method. The learning is presenting calculation of the encryption and decryption. The learning course is the study of cryptographic methods GOST. Learning software is also designed so that the method can be more easily understood GOST both algorithms and operations contained in this GOST method.
