Scan performed between 18th of January and 3rd of February 2016

December 2015 scan results

Past few months were a bit eventful so I wasn’t able to dedicate as much time to cipherscan as I’d like.

So not to make the results bitrot any more, I’m posting them without the detailed analysis.

There were no interesting changes compared to November anyway – just continuation of established trends.

Scan performed between 15th of December and 26 of December 2015.

November 2015 scan results

Number of servers which support TLS has grown by 1.3% since last month.

Cipher suites

Surprisingly, 3.2% more servers support just AES cipher suites now. At the same time we lost 3.7% market share of Camellia.

The good news is that RC4 support has dropped by 4.7%. Unfortunately, the amount of servers which default to RC4 is still rather high, at a 4% mark level.

Ciphersuites which are completely insecure have lost just 0.5%.

Essentially no change in server side vs client side cipher ordering, with just a small increase in the former.

Key exchange

Ciphersuites which provide forward secrecy are still growing, with ECDHE gaining 0.7% and support for ECDHE and DHE at the same time gaining 0.3%.

As usual, most of the gains are caused by the P-256 curve, with it increasing by 0.65%.

We’re now at 85% mark for servers which prefer forward secure ciphersuites, an increase of 1.11% since last month.

Hash and signature algorithms

Support for the obsolete RSA-MD5 signature algorithm continues to drop, but rather slowly, loosing just 1.1% since previous survey.

Fortunately, servers which are limited to just RSA-SHA1 signatures are also dropping, showing 0.3% fewer servers which do force this mechanism on clients. Support for stronger algorithms like SHA256 is still rather slow on the up tick, gaining just 0.7%.

Vulnerabilities

Little changes here, still 3.5% of servers vulnerable to insecure renegotiation attacks and just under 2% vulnerable to CRIME attack.

Certificates

Use of SHA-256 signatures in certificates continues its rise as de facto the signature standard, gaining 1.5% since last month.

This is also the first time when signatures with ECDSA certificates broke double digits, through an increase of 0.6%. We are less than 5% away from two most popular signature methods both using SHA-256.

Only minimal changes in the key sizes department, just that the ECDSA 256 bit keys have also increased by 0.6%, gaining a double digit market share.

At the same time, 2.6% of servers use configuration in which they support both of those public key standards.

Protocols

Little to no changes here. SSLv2 and SSLv3 are loosing, TLSv1.0 more or less stable, TLSv1.1 and TLSv1.2 gaining. All changes below 0.5% mark.
