This article details the fascinating technical process by which a modern-day researcher successfully factored the RSA keys of a Certificate Authority from the 1990s. It delves into the cryptographic vulnerabilities present in older implementations of RSA, specifically due to insufficient key lengths and weaker random number generation. The author explains the mathematical challenges and the computational resources required to break these historical keys, offering a historical perspective on the evolution of digital security and the importance of robust cryptographic practices.
