Hi Niels,
Would you mind writing a short description of the algorithm for the manual? I think it should go under "Miscellaneous hash functions". Would be nice with some brief background on this hash function (origin, intended applications, when and where it's useful) plus reference docs for the defined constants and functions.
SM3 is a cryptographic hash function standard adopted by the government of the People's Republic of China, which was issued by the Cryptography Standardization Technical Committee of China on December 17, 2010. The corresponding standard is "GM/T 0004-2012 "SM3 Cryptographic Hash Algorithm"".
SM3 algorithm is a hash algorithm in ShangMi cryptosystems. SM3 is mainly used for digital signature and verification, message authentication code generation and verification, random number generation, etc.
Thanks for the backround.
Its algorithm is public. Combined with the public keyalgorithm SM2 and the symmetric encryption algorithm SM4, it can be used in various data security and network security scenarios such as the TLS 1.3 protocol, disk encryption, standard digital certificates, and digital signatures.
I think the above two sentences could be removed or shortened. I think the mention of TLS, with reference to RFC 8998, is the part most relevant for the Nettle manual. Besides that I think your text provides right level of detail.
According to the State CryptographyAdministration of China, its security and efficiency are equivalent to SHA-256.
This is relevant too.
Thanks for your reminder, the above is the information I provided. Do I need to submit it to the document through PATCH?
If you can prepare a patch for nettle.texinfo, that would be ideal.
