kandi X-RAY | exegesis Summary

exegesis is a C library typically used in Utilities, SSH Utils applications. exegesis has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

So you have an ssh public authentication key and you 'lost' the private key. Did you generate that key in the last two years on Debian or Ubuntu GNU/Lunix? Yes? Ok, great. $ cat id_dsa.pub ssh-dss AAAAB3NzaC1kc3MAAACBAIW0doTjIKPNwAjHogbLhXNxNlwdvHHKzFPgZ 5cpwF4a2e8YYlEyXo8gyoub5c2s0f8B61ZNkowc9tcN+Iy1aiE2LBloxds3IwWNpZ 8KnJruCX/mYbltUp3CNJP/8gmeL41akUddPJ5wg6pYjDY5z7Kd9lojhqKOn3qSPXZ JDJXJAAAAFQDZMKlBeKVX9/FCO5auyzPHxn6QnwAAAIBULtChrN1rGfAjIU8VZwQa rQNunGFDfstWNOcx0lvAm2DkQCVCFT8DUXlibHWQJJbeMk3DfOl02ItIAhMvTTAPM rb8vtFsB3Fcw7KAuK0cAJaY3R2S6/tBbWXch7SaaOQ4dxa+8hmEl54icW/me0H6Z0 SEDYEm3j8pnAUnPAu/pgAAAIALkFjo4rsTTcSyW841Gdy+rhsH4St3dd4ZXiTdDVh wCbpBqSqiYxZO/gBHdCDAIs2uD8+GElpv7Q5Hx0g5JYLoBCpa1O8R2UAZMapZORRE umPRs6buJ4GMf33S5f/WSqdFaMo1+/67VkvUS/9Drtb7Mz3aI/QUIh1H3gfT0xFIm A== lamer@gnubuntu. First you'll need the fingerprint. $ ssh-keygen -l -f ./id_dsa.pub 1024 b2:f0:f6:47:19:64:ff:8e:8f:90:75:bd:57:6c:71:0c ./id_dsa.pub. Now look for that fingerprint in the generated fingerprint database files. You can just use 'grep' for this. $ grep b2:f0:f6:47:19:64:ff:8e:8f:90:75:bd:57:6c:71:0c dsa_1024_32_le.out b2:f0:f6:47:19:64:ff:8e:8f:90:75:bd:57:6c:71:0c 25191 dsa 1024 32 0. Oh, it's your lucky day! You're on the list.

            Loop takes less than 1 cycle despite dependency between iterations
            Asked 2020-Jan-18 at 03:52

            I wanted to benchmark the time needed to do a single addition on my Skylake (i5-6500) CPU. C is low-level enough for me, so I wrote the following code:

            ...

            ANSWER

            Answered 2020-Jan-18 at 03:49

            The core frequency and the TSC frequency can be different. Your loop is expected to run at 1 core cycles per iteration. If the core frequency happens to be twice as the TSC frequency for the duration of the loop execution, the throughput would be 0.5 TSC cycles per iteration, which is equivalent to 1 core cycles per iteration.

            In your case, it appears that the average core frequency was slightly higher than the TSC frequency. If you don't want to take dynamic frequency scaling into account when doing experiments, it'd be easier to just fix the core frequency to be equal to the TSC frequency so that you don't have to convert the numbers. Otherwise, you'd have to measure the average the core frequency as well.

            On processors that support per-core frequency scaling, you have to either fix the frequency on all the cores or pin the experiments to a single core with fixed frequency. Alternatively, instead of measuring in TSC cycles, you can use a tool like perf to easily measure the time in core cycles or seconds.
