Here's an article about the NSA cracking some parts of the web: https://arstechnica.com/information-technology/2015/10/how-t... """
For commonly used 1024-bit keys, it would take about a year and cost a "few hundred million dollars" to crack just one of the extremely large prime numbers that form the starting point of a Diffie-Hellman negotiation. But it turns out that only a few primes are commonly used, putting the price well within the NSA's $11 billion-per-year budget dedicated to "groundbreaking cryptanalytic capabilities."
