RE: [NSE] Script ssl-enum-ciphers should not penalize 3DES

["Rob Nicholls" <robert () robnicholls co uk>]

I'm fairly happy with that suggestion. I believe Nessus also treats 112-bit
(i.e. 3DES) keys as a "High" strength cipher.

Subject: [NSE] Script ssl-enum-ciphers should not penalize 3DES

As of now, script ssl-enum-ciphers is rating cipher suites based on 3DES
(112-bit keys) the same as those using plain 56-bit DES.

Given that 56-bit keys are considered easily within the reach of average
adversaries while 3DES keys are deemed safe at the moment, I would like to
propose that we change the rating to treat 3DES on par with 128-bit ciphers.
This position is supported by SSL Labs, which does not flag presence of 3DES
cipher suites, while rating "Cipher Strength" of such sites as "Green".

More details at https://github.com/nmap/nmap/issues/474

Please voice any concerns with such a change.


Cheers,
