About GOST-CRYPTO hash
GOST-CRYPTO refers to a set of cryptographic algorithms and standards developed in Russia under the State Committee for Communications and Information Technology (Gosudarstvennyy Komitet po Svyazi i Informatizatsii, known as Goskomsvyaz). These algorithms are part of the GOST (ГОСТ) family of standards and encompass various cryptographic primitives such as encryption, hashing, and digital signatures.
Components of GOST-CRYPTO
Encryption Algorithms:
- GOST block ciphers: Includes algorithms like GOST 28147-89, which is a 64-bit block cipher with a 256-bit key length. It has been used in various applications requiring encryption, including in Russian governmental and commercial systems.
Hash Functions:
- GOST R 34.11-94 (GOST 256): The first standardized GOST hash function, producing a 256-bit hash value. It has been used for data integrity verification and digital signatures.
- Streebog (GOST R 34.11-2012): An updated version of the GOST hash function, supporting hash outputs of 256-bit, 512-bit, and 1024-bit lengths. It is known for its robust security features and is used in modern cryptographic applications.
Digital Signature Algorithms:
- GOST R 34.10-94 (GOST R 34.10-2001): Specifies the digital signature algorithm using GOST 28147-89 for encryption and GOST R 34.11-94 for hashing.
- GOST R 34.10-2012: An updated version supporting elliptic curve cryptography (ECC) for digital signatures.
Characteristics of GOST-CRYPTO
Security and Standards:
- GOST-CRYPTO algorithms are developed and maintained by the Federal Service for Technical and Export Control (FSTEC) of Russia and are part of the Russian national cryptographic standards.
- These algorithms are designed to provide strong security assurances against cryptographic attacks, meeting the requirements of Russian governmental and commercial sectors.
Usage:
- GOST-CRYPTO algorithms are widely used in Russia for securing sensitive information in governmental and financial systems, as well as in commercial applications.
- While historically prominent in Russia, their international adoption has been influenced by the prevalence and standardization of other cryptographic algorithms such as AES (Advanced Encryption Standard) for encryption and SHA-2/SHA-3 for hashing.
Summary
GOST-CRYPTO refers to a comprehensive set of cryptographic algorithms developed under Russian standards, covering encryption, hashing, and digital signatures. These algorithms are designed to provide robust security features and have been integrated into various governmental and commercial applications in Russia. However, their global adoption has been limited compared to more widely recognized cryptographic standards such as those recommended by NIST (National Institute of Standards and Technology) in the United States.
