   At the top of the page it talks about Diffie-Hellman key exchange and   
   says it is a popular cryptogrphic algorithm that allows Internet   
   protocols to agree on a shared key.....   
   -snip-   
   Logjam allows a man-in-the-middle attacker to downgrade vulnerable TLS   
   connections to 512-bit export-grade cryptography....   
   -snip-   
   Websites, mail servers, and other TLS-dependent services that support   
   DHE_EXPORT ciphers are at risk for the Logjam attack. We use   
   Internet-wide scanning (https://zmap.io) to measure who is vulnerable.   
      
   Note: I've typed the above lines by hand, hopefully I didn't make too   
   many typos.   
      
   weakdh.org opens as a http:// page.   
      
   The comment was made by RC Primak, who to me seems like He knows what   
   He is talking about.   
      
   I just thought I'd share the info here in case it was important to the   
   folks in this echo that are computer professionals, and they hadn't   
   heard about Logjam yet, so they could investigate it for themselves.
