I just checked Amazon's certificate and it shows it is SHA-1 signed. But Chrome does not show any warnings, like it does (the red cross) for other websites with SHA-1 signed certificates.

Am I looking at this wrong?

Chrome is flagging SHA-1 signed certs based on their expiration date.

For the full details on the different dates and indicators, please review:


The cert Amazon has deployed expires Oct 2nd, 2015. enter image description here

  • Awesome! Nitty gritty detail.

  • @k1DBLITZ This question has some very comprehensive discussion on the sunsetting of sha-1 on major sites.
