Can this sha256 be cracked? - bradman99.94 - 10-11-2011 01:22 PM
I am trying to figure out if I can crack a raw sha256 hash.
But I don't know how to do it, or if it is even possible.
The plaintext is a sentence type string, rather than a password.
I already know two parts of the sentence/string (I will call the known parts "fixed string #1" and "fixed string #2").
I also have 2 complete wordlists, which contain all the possible remaining variables:
List 1 is short (it contains under 50 words)
List 2 is large (size ~2 gb).
I know the order in which the components of the string are assembled.
The plaintext goes like this:
[fixed string #1] [word from list 1] [word from list 1] [word from list 1] [word from list 1] [fixed string #2] [word from list 2] [word from list 2] [word from list 2] [word from list 2]
So: there is a fixed string, followed by 4 words from list 1; then a second fixed string, followed by 4 words from list 2.
Together, they make the plaintext (a sentence) which has been hashed.
Can this be hash be cracked in oclHashcat?
How would I do it?
Thanks for your help...

using hashcat-utils you can use combinator to combine 2 dictionaries, but not not 8. also, the max length of the plaintext password supported is 15.
