Re: How high can you get

But it's write one core on prompt. But if i see on task manager Two cores work at 100% As rolf explained.. 1 core is reserved for the GPU stuff.. That is: You have 2 cores . 1 core goes to the GPU, you now have 1 core left . Which is the 1 core you see .. The other is dealing with telling the GPU w...

Re: hashcat

Could you give example commandline for bruteforce?... Simply can't make it work... Tried all combinations I can think of with following, a=3.. And then some bruteforce specific commands... PS: Very slow beta version. Only 30M passwords per second for MD5. Feel the difference: http://picstorage.narod...

Re: Maths behind MD5

Interesting :) Beginning to understand it. And oh.. About this: Also.. Given a public key.. I assume it's possible to find different factorizations .. Is it necessary to check each of the factorizations possible, as only one of them is 'correct' ? .. Ofc. making it even harder... / longer... "differ...

Re: Maths behind MD5

Understanding more about RSA... And why factorizing is interesting... I found this Java application: http://www.alpertron.com.ar/ECM.HTM. It uses Elliptic curves to factorize numbers. And has no limit (System limited) to the size of the input. For a test, I entered my own digital certificates public...

Maths behind MD5

Hey,

Does someone have a good / great article on the maths behind MD5?
Really, anything will do.. I need an introduction to the Mathematics behind cryptographic algorithms..

I'm a little into the use of large prime numbers already.. Got a book on the subject which I'm reading.. :)

Regards,

I dunno if CUDA has any specific GPU limitation. I know for a fact Windows will not boot if there are more than 8 active GPUs. I would like to point out that I have to wait about 45 seconds for the windows logon screen to come up. I sits at a blank screen. That maybe why Crucifix said "I know for a...

For BarsWF it does help a little at i7.
But why.. ?
All I know that it does, is split the core 'theoretically' into two, presenting it as duo.. All calculations have to be done one one core anyways....

Re: sha 512 decode

No.. No.. No...

No, we cannot 'decode' it.. It's hashed!
No, we won't crack it for you. It's not a public service thing.
No, Bars doesn't yet have support for SHA512 (Not even non-salted)..

On the other hand. Will be nice when SHA512 *is* implemented :)
