comment With PBKDF2, what is an optimal Hash size in bytes? What about the size of the salt?
Given the low security cost of reusing an occasional PBKDF2 salt, the cost to the entropy pool of generating an extra 8 random bytes (and the memory and disk cost to store them), is 128 bits really worth it over 64 bits? Would adding a constant "purpose" string to the salt achieve the goal even better? (I know this is a bit nit-picky; it's just something I've been thinking through recently and was looking for other opinions.)

comment How a malware executes remote payload
Plus also directly interpreting it (performing actions directly based on the payload), or passing it to another tool to interpret (such as bash or python).
