This article introduces the fundamentals of encryption, compares symmetric (AES) and asymmetric (SM2) algorithms, clarifies the role of HTTPS as a protocol suite, distinguishes hash functions from encryption, and walks through a national‑standard mutual authentication flow using SM2 and SM4.
Ant Financial's MorseCrypto team secured first place in the 2024 Financial Cipher Cup second‑stage competition by delivering highly optimized SM2, SM3, and SM4 implementations on X86 and ARM platforms that achieve up to 4.3‑times faster verification while meeting strict security and memory constraints.
This guide introduces GmSSL, an OpenSSL‑compatible toolbox that implements China’s national cryptographic algorithms, explains its lightweight and cross‑platform features, and provides step‑by‑step instructions for compiling, installing, and using core commands, SM4/SM3/SM2 operations, and certificate authority workflows.
This article demonstrates how to secure a Spring Boot 2.7.7 application using JWT, Spring Security, and a custom SM4‑based PasswordEncoder, covering dependency setup, security configuration, custom authentication components, token validation filter, and a login endpoint implementation.
The article introduces China’s national cryptographic standards—including SM1, SM2, SM3, SM4, SM7, SM9 and ZUC—explaining their origins, key features, implementation details, comparison with international algorithms, and typical use cases such as AD‑WAN, IPsec, and 4G/5G VPDN networks, highlighting their role in enhancing information security.
This guide explains fundamental data encryption concepts, introduces PHP's openssl_encrypt function, compares common encryption modes, shows how to generate keys and initialization vectors, and provides a complete SM4‑CBC implementation with sample code and practical security precautions.
This guide explains how Nacos 2.1.0 introduces built‑in configuration encryption, how to add encryption plugins on the server, and how to mark configuration entries with a special prefix so that they are automatically stored and transmitted as ciphertext.
TencentKona 8.0.4 introduces an SM2/SM3/SM4 JCE provider for Chinese national cryptographic algorithms, parallel G1 Full GC, parallel heap inspection, and various performance enhancements, all demonstrated with a micro‑service encryption example and detailed curl commands for practical use.
