Sm3 hash function
Webb23 mars 2001 · Hash function modules define one function: new ( [string]) (unkeyed hashes) new ( [key] , [string]) (keyed hashes) Create a new hashing object and return it. The first form is for hashes that are unkeyed, such as MD5 or SHA. For keyed hashes such as HMAC, key is a required parameter containing a string giving the key to use.

Webb30 apr. 2013 · SM3 [12] is the Chinese cryptographic hash standard which was announced in 2010 and designed by Wang et al. It is based on the Merkle–Damgård design and its compression function can be seen as a block cipher used in Davies–Meyer mode. It uses message block of length 512 bits and outputs hash value of length 256 bits. Webb// Write "Write" method for the hash abstract, is the standard interface method of the GO language hash class, for public methods, external calls. // The function is intended to write an input message in accordance with the grouping, iteration, and compression function specified in the SM3 national standard, write 8 word registers.
Webb13 maj 2024 · SM3 hash function [ 38] is the Chinese cryptographic hash function standard, which is similar to SHA-256. However, SM3 has stronger message dependency and more complex step function than SHA-256. ShangMi 3 (SM3) is a cryptographic hash function used in the Chinese National Standard. It was published by the National Cryptography Administration (Chinese: 国家密码管理局) on 2010-12-17 as "GM/T 0004-2012: SM3 cryptographic hash algorithm".

Webb10 nov. 2024 · Many “old” program still use Keccak, and do not upgrade to official SHA-3 standard. “old” code based on Keccak does not generate the same hash value as SHA-3 does. So, if using a “sha3” library, you should be crystal clear that the library is based on Keccak or based on standard SHA-3.
