SHA-1을 깼다고 합니다.

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.
