CRYPTO30YEARS

Summary from the TLDR InfoSec newsletter

A historical review of major cryptographic algorithms from World War II onward shows that most designs fail to remain unbroken past 30 years. Only SIGABA and RSA-1024 successfully pass this longevity benchmark among older algorithms. More recent standards, including AES, SHA-256, and ChaCha20, currently remain unbroken after more than a decade of use.
