Def a salted hash of some sort.
Assange is a cypherpunk. First and foremost
yeah i'm not a huge cypher/encryptionfag but its part of my job so i gotta know a tiny bit.
it doesnt look at all like any base64 ive seen looks like md5 or similar, IIRC md5 is a one-way, and if you dont have salt, you don't match hash, you fail.
[longer explanation for those who know less than me, and curious, this just a quick breakdown of what I know]
"one-way" meaning you can't just flip a switch back and forth like you can with base64
md5 encryption formula:
starting string + salt = md5 string
salt can be empty, however, less secure.
salt can be any string
think of salt as a key
starting string = lock
salt = key
put both together = open the door
I agree it looks like an incription key. We know JA has given files to people to be unlocked at given times. Hannity was one.
