MySQL TEXT type character encoding storage limitations UTF-8 database design

This paper provides an in-depth analysis of the storage mechanisms and maximum length limitations of TEXT type fields in MySQL, examining how different character encodings affect actual storage capacity, and offering best practice recommendations for real-world application scenarios.
Understanding RSA Key Pair Generation: Extracting Public Key from Private Key

RSA Algorithm Key Pair OpenSSL Key Extraction Asymmetric Encryption SSH Authentication

This article provides an in-depth analysis of RSA asymmetric encryption key pair generation mechanisms, focusing on the mathematical principles behind private keys containing public key information. Through practical demonstrations using OpenSSL and ssh-keygen tools, it explains how to extract public keys from private keys, covering key generation processes, the inclusion relationship between keys, and applications in real-world scenarios like SSH authentication.
