GOST is a well-known block cipher as the official encryption standard for the Russian Federation. A special feature of GOST is that its eight S-boxes can be secret.

We pride ourselves in delivering Military-Grade encryption throughout the years holding a transparent track record of bullet-proof security. Security made easy GhostECC provides a Triple Layer Encryption Standard (521-bit ECC, AES 256-bit, 2048 SSL) to encrypt each and every process of its secure communication platform. Gost — Reverse lookup, unhash, and decrypt GOST (256 bit) is hash function, defined in the standards GOST R 34.11-94 and GOST 34.311-95, is a 256-bit cryptographic hash function. It was initially defined in the Russian national standard GOST R 34.11-94 Information Technology - Cryptographic Information Security - Hash Function. More information about the GOST algorithm encryption can be found here. The input string encoding is expected to be in UTF-8. Different encoding will result in different hash values. Unicode is considered best practices. GOST is of interest for products which must inter-operate with Russian equipment and as a backup algorithm to be used in conjunction with AES in applications where depending on a single cryptographic algorithm remaining secure is undesirable. Key Features and Benefits 128 bit Data Path 256 Bit Key Template:Infobox Encryption method The GOST block cipher, defined in the standard GOST 28147-89, is a Soviet and Russian government standard symmetric key block cipher. Also based on this block cipher is the GOST hash function. Library contains polyfill methods of Crypto and CryptoSubtle interfaces and extends algorithms for GOST-oriented crypto scenarios. For non-GOST algorithms execution passthrough to native CryptoSubtle method. The library implements GOST methods and algorithms described in the following references If we have a diverse population of at least $2^{79}$ different 256-bit GOST keys generated at random, with access to $2^{32}$ CP per key, one can recover one of these 256-bit keys in total overall time of about $2^{101}$ GOST encryptions. Now theoretically a cipher is broken if there is an attack that is (significantly) faster than brute force.

This paper observes approaches to algebraic analysis of GOST 28147-89 encryption algorithm (also known as simply GOST), which is the basis of most secure information systems in Russia. The general idea of algebraic analysis is based on the representation of initial encryption algorithm as a system of multivariate quadratic equations, which define relations between a secret key and a cipher

Gost turns messages of different lengths into a specific length, 256 bit result. The result is divided into eight 32 bit parts, and filled up with enough zeros as needed to increase the size of the message to the desired 256 bits. An 2008 attack was documented to have broken the full round GOST hash function.

In January 2016, a new standard for symmetric block encryption was established in the Russian Federation. The standard contains two encryption algorithms: Magma and Kuznyechik. In this paper we propose to consider the possibility of applying the algebraic analysis method to these ciphers. The Center for Education and Research in Information Assurance and Security (CERIAS) is currently viewed as one of the world’s leading centers for research and education in areas of information security that are crucial to the protection of critical computing and communication infrastructure. The GOST block cipher is the Russian encryption standard published in 1989. In spite of considerable cryptanalytic efforts over the past 20 years, a key recovery attack on the full GOST block cipher without any key conditions (e.g., weak keys and related keys) has not been published yet. However, those countries have their own sets of GOST S-Boxes and they're moving to their own crypto standards (Kalina in Ukrain, Belt in Belarus etc.). There are some open source encryption tools like GostCrypt that are based on GOST. GOST is also implemented in OpenSSL and Crypto++ frameworks.
