comment XKCD #936: Short complex password, or long dictionary passphrase?
@AlexBowe you reduce the entropy by discarding hard-to-say sentences from diceware. 5 words is only ~64.6 bits of entropy if you don't discriminate on the answers it gives you.

comment Security of SHA256 and Bitcoins
it should be noted that the phrase "SHA-1 is broken" has a very specific meaning in cryptography. it basically means that a collision attack has been discovered that is faster than a birthday attack. it does not mean that somebody could reverse a hash to get the original string.

comment Steganography to hide text within text
it sounds like a good technique. unicode equivalent letters might also work in a similar fashion as the block vs cursive in their cipher.

that sounds like what i am after. how would people verify this? ie what is the process of comparing the public key and the signed post?

comment Facebook data visibility to admin staff
fair enough. i didn't consider a key accessible via a password. if the password were hashed in the db then this would also be ultra-secure. since i have no way of knowing if facebook does indeed do this (although i suspect they don't) then this is a valuable contribution. cheers!

hmmm that's interesting, but i am asking about facebook specifically. clearly facebook doesn't do this since users do not have to enter keys or certificates during the login process.
