Cryptographic Hash Algorithm of SHA Series

The hash algorithm, is used to map input data with variable (but usually with an upper limit) length to a fixed-length output result. The output result is usually called hash value, message digest or fingerprint. SHA, which stands for Secure Hash Algorithm, was designed by the United States National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) as part of the series of hash algorithms. This article will introduce the properties, security requirements of hash algorithms, and the SHA series algorithms.

Understanding the Identity-Based Cryptography Algorithms SM9

Shamir proposed the concept of identity-based cryptography (IBC) in 1984. In the system of IBC, the user's private Key is calculated by the Key Generator Center (KGC) according to the master key and the user ID.

Let's Talk About SM2 Cryptographic Algorithm

SM2 is an asymmetric cryptographic algorithm proposed by the State Cryptography Administration, which utilizes the mathematical theory of elliptic curves and is optimized in terms of security, efficiency and storage space. SM2 can be divided into two types based on prime number field and binary extension field.
