## What it is
A curated collection of texts for China's national cryptographic industry standards (GM/T), covering algorithms like SM2, SM3, SM4, and ZUC as well as related specifications for VPNs, certificates, and cryptographic devices. It serves as a reference repository of standard documents rather than executable software.

## Use cases
- find the official SM2 elliptic curve signature standard text
- look up SM4 block cipher specification
- reference ZUC stream cipher algorithm documentation
- check GM/T standard numbers and names for Chinese cryptography compliance
- study Chinese national cryptographic algorithm requirements
- find SSL VPN or IPSec VPN GM/T specification documents

## When to choose
- you need the actual text of Chinese GM/T cryptographic standards
- you are implementing or auditing SM2/SM3/SM4/ZUC-based systems
- you need a quick index of GM/T standard numbers and titles

## When to avoid
- you need software libraries implementing these algorithms rather than the standards themselves
- you need up-to-date standards beyond what the repository has collected
- you need internationally recognized standards like NIST or ISO cryptography

## Facets
- artifact type: dataset
- maturity: maintenance
- function: cryptography, documentation, security
- domain: security, documentation, legal
- platform: cross-platform
- tags: chinese-national-cryptographic-standards, gm-t, sm2, sm3, sm4, zuc, standards-texts, reference, cryptography
