comment Is it still unsafe to email credit card number nowadays?
Trusting this person also means trusting them to secure their computer against malware. I.e. trust nobody :)

comment What cryptographic algorithms are not considered secure?
If you're on a 32 bit server, the performance difference from good implementations of sha256 (224) and sha512 (384) is more noticeable than on a 64 bit server. There is still a difference because sha256 has 64 rounds, sha512 has 80 rounds. (for every 512 or 1024 bit chunk of data respectively). Interestingly, sha224 and sha384 are a little bit slower than their counterparts, because they do the same calculations and then strip off some of the result. (here it is in python)

comment How is “anonymous” getting ahold of all these plain-text passwords
Yeah, there weren't any news about the sites that hadn't been hacked. Of course I agree that it's a huge problem none the less.

"most sites ... will store it in plain-text"? Is there any reference for this? I find it hard to believe.
