comment 2 comparable hashes generated from one string
@user4982 There's an opportunity cost involved in setting up scrypt. It takes up development time that could be used to lock down unneeded services, to set up AppArmor, to look for SQL injection/XSS/CSRF, or to install fail2ban. All of those things take higher priority in my mind.

comment Is there any restriction in using lossless compression algorithms for huge key sizes?
For storing the private key, you can store the seed that you used to get the key instead. You should be able to fit a pretty good seed in 24 bytes.

comment Why is the complexity of RSA-1024 80 bit and not 86 bit?
@poncho If you're writing a standards document, you want it to be as clear as possible, even to people unfamiliar with public key cryptography.

@RickyDemer Nope. Memory usage is only a function of $r$. nightcracker, I'm not sure what your point is.

comment The specification of modern, non-communicating cipher machinery
How is sending the message via semaphore different from sending it through a modem? Can an adversary observe the message in transit, or tamper with it?
