Here you can calculate online GOST-CRYPTO hashes for your strings. Put your string into form below and press "Calculate GOST-CRYPTO hash". As a result you will get GOST-CRYPTO hash of your string. If you need another hash calculators, for example: HAVAL128-4, HAVAL192-3, SNEFRU256 or TIGER160-3 you can find it into appropriate section.
The GOST 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. The equivalent standard used by other member-states of the CIS is GOST 34.311-95.
This function must not be confused with a different Streebog hash function, which is defined in the new revision of the standard GOST R 34.11-2012.
The GOST hash function is based on the GOST block cipher.
GOST processes a variable-length message into a fixed-length output of 256 bits. The input message is broken up into chunks of 256-bit blocks (eight 32-bit little endian integers); the message is padded by appending as many zeros to it as are required to bring the length of the message up to 256 bits. The remaining bits are filled up with a 256-bit integer arithmetic sum of all previously hashed blocks and then a 256-bit integer representing the length of the original message, in bits.
You've visit right place if you want to calculate GOST-CRYPTO hashes. Put string or even text into String to encode field above and press "Calculate GOST-CRYPTO hash". You will get GOST-CRYPTO hash of your string in seconds. You can also copy this hash right to your clipboard using the appropriate button.
Keep in mind that our website has a lot of other calculators, like MD2, MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512-224, SHA512, RIPEMD128, RIPEMD160, RIPEMD256, RIPEMD320, WHIRLPOOL, SNEFRU, SNEFRU256, GOST, ADLER32, CRC32, CRC32B, FNV132, FNV1A32, FNV164, FNV1A64, JOAAT, etc. So all what you need to calculate any of these hashes is remeber our web site address - SHA256Calc.com
