GOST Hash Generator Online
A GOST Hash Generator is a cryptographic tool that converts input data (text, password, or file) into a fixed-length hash value using the GOST hashing algorithm. GOST (ГОСТ in Russian) is part of a suite of cryptographic standards developed in the Soviet Union and later Russia. The official name is GOST R 34.11-94, established in 1994, and it produces a 256-bit (64-character hexadecimal) hash value.
Designed as a national standard, the GOST hash function is notable for its strong mathematical foundation and close ties to block cipher operations. Although less common internationally compared to SHA or MD5 families, it has been widely used in Russian government and financial systems.
Key Features
- Fixed-Length Output: Produces a 256-bit hash represented as a 64-character hexadecimal string.
- Block Cipher Based: Built upon the GOST 28147-89 block cipher for its internal structure.
- One-Way Function: Impossible to reconstruct the original input from the hash.
- Collision Resistance: Designed to prevent two different inputs from producing the same hash.
- National Standard: Required for use in many Russian cryptographic applications.
Common Use Cases
- Digital Signatures: Used in Russian cryptographic signature standards.
- File & Data Integrity: Ensures data has not been changed during storage or transmission.
- Password Security: Hashing credentials in secure systems.
- Government & Financial Systems: Required in certain regulated environments within Russia.
- Research & Interoperability: Explored in international cryptographic research as an alternative to SHA family functions.
How to Use
- Input is divided into 256-bit blocks.
- Each block is processed with the GOST 28147-89 block cipher in a compression function.
- The process iterates through all blocks of the input.
- The final output is a 256-bit hash value in hexadecimal format.
Common Questions
“GOST” stands for Gosudarstvennyy Standart (Государственный Стандарт), meaning State Standard in Russian.
GOST R 34.11-94 is considered reasonably secure, but newer versions exist. In 2012, Russia introduced GOST R 34.11-2012 (Streebog), which is based on more modern designs and provides stronger security guarantees.
It has been widely used in Russia and CIS countries, especially for governmental, financial, and regulated cryptographic applications.
