How many sha1 hashes per second can current hardware (say a 500$ gpu) compute, when the input is 256 byte long? (or any other length). The question behind is how long (or how costly) is it to mount a ...
All modern password hashing schemes are deliberately designed to include a huge amount of "busy-work", to limit the speed with which an attacker would be able to conduct password hashing attempts. ...
How long would it take to bruteforce an AES-128 protected pdf knowing the key is 20 letter long and that the charset is A-Z,0-9?
The question says everything, knowing that a pdf is protected using standard Adobe password encryption that comes with Acrobat Pro (which as far as i know is AES 128) how much would it take to ...
this company claim Scrypt mining by ASIC (on crypto currencies who use scrypt hashing as proof of work) scrypt is made to keep ASIC/FPGA attackers away, is that claim expired?
How are GPU's provisioned for password cracking? Do all, if not most cracking programs have special GPU aware software or do they just function at the basic driver or API level of the device? Can it ...
I came across this very alarming sounding thread which indicates a GPU with about half the compute capacity of the GPU currently powering the monitor I type this on is capable of 11.5k c/s. I'm not ...
Are there implementations of password hashing algorithms for major frameworks that utilizes specialized hardware like GPUs/FPGAs?
It is common knowledge that password cracking attempts can greatly benefit from specialized hardware such as large clusters of GPUs or FPGAs. Are there any implementations of the commonly recommended ...
Brute-force password cracker programs which claim GPU support include John the Ripper, ighashgpu, oclHashcat, and others. oclHashcat appears one of the more popular, but I am not sure which AMD/ATI ...
Today, almost all desktop and most mobile operating systems and devices support some version of OpenGL. I'm wondering about the security implications of that: In many cases, the GPU has complete and ...
