Linux Crypto Driver Development: Hash Algorithm

by

Overview The Linux kernel provides a complete cryptographic algorithm framework (Crypto API), supporting hardware acceleration and software implementation for various cryptographic operations. In actual driver development, we often need to integrate multiple cryptographic algorithms (such as SHA256, AES-CTR, RSA2048, etc.) into the same cryptographic hardware device, utilizing its dedicated computational capabilities to enhance system performance … Read more

Why Did Google Crack the SHA-1 Algorithm?

A few days ago, the news of Google cracking the SHA-1 algorithm flooded my social media feed. In fact, the term “crack” is not entirely accurate, it should be that they published an example of breaking the SHA-1 algorithm. Regarding this news, I saw two different comments: A: Wow, that’s amazing! They actually cracked an … Read more

Understanding RSA Algorithm Principles: Overview of Common Encryption Algorithms

Alan Turing was primarily responsible for breaking the German Enigma cipher system during World War II. Decrypting codes required extensive computation, and Turing understood that to do a good job, one must first sharpen their tools. Thus, a computer called COLOSSUS was developed in 1943, and a total of 10 such electronic computers were produced, … Read more
