Is it true that SHA-1 has been broken

Well that is what this article says:

If true then ..... what

Relax... it still takes 2^69 tries. That is 590,295,810,358,705,651,712 hash operations. To brute force sha-1 it takes 2**80. This is only 2**11 times faster then a brute force attack... thats 2048 times faster. Its significant but it's not that big of a deal. It is no more significant then if someone with a 2000 node cluster tried to brute force your hash (which is completely feasible...especially for large government agencies like the NSA). In other words, if you were capable of performing 1 trillion (1,000,000,000,000) hash operations per second, it'd still take nearly 19 years for a collision to be found. I assume the NSA can knock that number down to under 24 hours, but thats expected of them. For anyone else in the world, assuming your not being followed by the NSA... and god help you if you are... sha-1 will still be fine and the entire internet security infastructure will not need to be redesigned.


Interesting but bit torrent hashes are ok for now. That could change with faster processors, but nothing to worry about anytime soon, unless you plan to be here when we have 1 or 100 trillion hash functions per second on a single desktop.

wrong thread?

in regards to sha-1: read the comments in the article. i wouldn't worry about it.

Yeah, is sounds like you need a supercomputer to be able to break it.

Don't know of many supercomputers that sit around with nothing to do but break SHA-1. lol

i don't have a basement

/starts making plans to break into cpugeniusmv's basement

[black_magiic]

I shall join you in that endeavour.

Unless theres a simple Exploit on the OS of a security device itself to get the information would be take a phenominal amount of time...

IBM's Cell chip anyone?

I wonder, from what i heard that chip has awsome number crunching ability, and you can have as many as you want clustered together. I wonder how many years before these will be available, and then how fast could they crack it....
