comment Steganography to hide text within text
@this.josh of course yes but its really obvious to an eavesdropper when something like a signature jpg (which looks the same to the human eye) has a different hash every email. its a giveaway. a visually different photo each time would not arouse the same suspicion though and this would be a good way to do it.

@this.josh i think when i wrote this i was interested in using regular email (text) because it is ubiquitous.

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.

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?
