TLS scan results for November 2015
by Hubert Kario
07 Dec '15
07 Dec '15
Not much changes since October, mostly continuation of established trends. Curiously, percentage of servers supporting just AES ciphers jumped suddenly just over 3%. More detailed analysis on my blog:

TLS scan results for October 2015
by Hubert Kario
01 Dec '15
01 Dec '15
The biggest change since July is that over 10% fewer servers use certificates with SHA-1 signatures. Because I was rather busy for the past few months I wasn't able to work on the scan analysis on-time. So this month's analysis is on a longer time scale. More detailed analysis on my blog:
https://securitypitfalls.wordpress.com/2015/11/29/october-2015-scan-results/
