comment Domain socket authentication as in MySQL and PostgreSQL secure?
As far as I'm aware, TCP/IP vs. Unix sockets are just seen as different communications layers, which the actual protocol is agnostic to. That being said, I've only taken enough of a look at the protocol to emulate a couple of the packet types, and that was entirely on TCP/IP.

comment Domain socket authentication as in MySQL and PostgreSQL secure?
Anecdotal evidence: I know that by default MySQL will do some form of challenge-response auth which is difficult to break, but the actual communications after that are not encrypted by default. You also have to have encryption enabled on BOTH the client and server for it to be enabled. There's also no integrity protection - I wrote a small tool for injecting queries into existing connections.

comment Is there a reason to use TrueCrypt over VeraCrypt?
I'm with @CodesInChaos on this one. I may be ill, and it may be a coffee-less Tuesday morning, but I cannot fathom why anyone would think OTP would be even vaguely useful in FDE.

comment Is it even possible to hack a television channel?
@EllieKesselman It's from the movie "Hackers", which everyone should definitely see. Cheesy as hell, soundtrack by The Prodigy, stars Angelina Jolie from when she was practically a kid.

comment What attacks, if any, are possible against Security Support Provider Interface (SSPI)?
@paj28 Sorry, yes, I should've been more clear. I guess I'm mainly referring to Negotiate and Digest SSP (SASL) as they're the two most common. But, as well as that, I'm interested in the security of how SSPI as an interface safely decides which protocol to use when there are mismatches in support between two endpoints.

comment How “enforcable” are email disclaimers
@CarlosBribiescas That is an amusing thought. Sadly, I don't know the answer. It's probably never been tested in court.

comment How do I use “openssl s_client” to test for (absence of) SSLv3 support?
@RogerLipscombe Right, so what's not working there? SSLv3 is not listed, so it's not supported.

comment Add a file as entropy source for /dev/random
Care to explain what specific requirement you have that /dev/urandom doesn't solve? The term "true-random entropy" doesn't make any sense in this context.

comment Add a file as entropy source for /dev/random
You can't really "consume" entropy. Besides, /dev/urandom is designed to provide an essentially unlimited CSRPNG through the use of AES-CTR keyed from /dev/random, which means you're guaranteed to have strong random numbers as long as you've got even a bare minimum of collected entropy. You'd have to run some kind of tiny cut-down kernel on a low-entropy embedded device and pull gigabytes of random data from /dev/urandom to impact security in a negative way.

comment Add a file as entropy source for /dev/random
Can I just ask... why? What is the problem that you are solving by doing this? I mean, "for funsies" is completely fine, I just want to be sure you're not doing it because you expect some kind of tangible security improvement.
