As I understood brute force attack is measured in number of keys which in turns give time required based on speed of computer
It is quite interesting find out how effective an arbitrary computer is and estimate to total time required to try all number of keys in a given key space.
Are there any tools available to practically estimate the effectiveness of a computer to try all number of key in a key space to brute force attack block cipher.
key length: 32 key space: 2 ** 32 Time: 10 ^ 9 keys/sec = 4 sec 10 ^ 12 keys/sec = 4 ms
Theoretically we can calculate with all these assumption. But, is there any way/tool/application to measure speed of a computer and how many keys it can try per second without trying all number of keys in key space.
