Named after Odin's eight-legged horse from Norse mythology, Sleipnir gallops through keyspace at incredible speeds to find your perfect vanity SSH keys.\n\n## Compiling\nPlease checkout the [DOCS](docs/compiling.md) for information on windows and Linux compiles.\n\n## Usage\n\nBasic Usage\n```bash\n# Find \"cool\" anywhere in the SSH key\n./sleipnir -pattern cool\n\n# Find key ending with \"1337\" OR \"meng\" OR \"github\"\n./sleipnir -pattern 1337,meng,github -location end\n\n# Use the gpu and cpu to find keys\n./sleipnir -pattern mari -location end -gpu\n```\n\nFor **more** usage examples please go to the [DOCS](docs/usage.md)\n\n\n## Example\n\n```bash\n./sleipnir -pattern MENG -location end -ignore-case=false\n```\n```\nSleipnir galloping with 24 workers...\nHunting pattern: MENG\nPress Ctrl+C to stop\nExpected tries: 1.6777216e+07\n|Average keys per second: 977558| |Total tries: 4887855| |Calculated wait time: 0d 00h 00m 05s/0d 00h 00m 17s|\n|Average keys per second: 975424| |Total tries: 9764953| |Calculated wait time: 0d 00h 00m 10s/0d 00h 00m 17s|\n...\n|Average keys per second: 979482| |Total tries: 29326450| |Calculated wait time: 0d 00h 00m 30s/0d 00h 00m 17s|\nMade it in 33054311 tries\n\nKEY FOUND :)!\nOpenSSH Private Key:\n-----BEGIN OPENSSH PRIVATE KEY-----\nRemoved so nobody would actually use this key :p\n-----END OPENSSH PRIVATE KEY-----\n\nPublic Key:\nssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAII44C87jrgvZi/pkNUVpwb0jlnUGXkiUu+/RMS5wMENG\nAll goroutines closed successfully\n\n```\n\u003e [!NOTE]  \n\u003e If you want the PKCS#8  format instead of OpenSSH you will have to run sleipnir with -verbose\n\n## Tests\nBenchmark the speed of the ssh keygen per core and the Sleipnir keys/s:\n```\ngo test -bench .\n```\n\nTest if we are generating valid ssh keys:\n```\ngo test -v\n```\n\n##### Flagegraph:\nRun sleipnir for a bit with the **-pprof** flag\nThen run the following command:\n```\ngo tool pprof -http=:8000 sleipnir.pprof\n```\nVisit http://localhost:8000/ui/flamegraph for the graph.\n\n## Benchmarks\n\n| GPU                     | keys/s | OS              | Version   | batch-size |\n|:------------------------|:------:|:----------------|-----------|------------|\n| GeForce RTX 4070 12GB   | ~26M   | Debian Linux 13 | 1.0.0     | 33554432   |\n| GeForce RTX 3080 10GB   | ~23M   | Arch Linux      | 1.0.0     | 16777216   |\n| GeForce RTX 3080 10GB   | ~17M   | Windows 11 23H2 | pre-1.0.0 | ?          |\n| GeForce RTX 3060 Ti 8GB | ~12.5M | Windows 11 23H2 | pre-1.0.0 | ?          |\n| GeForce RTX 4070 12GB   | ~9.5M  | Debian Linux 12 | pre-1.0.0 | ?          |\n\n| CPU                  |keys/s | OS              | Version   |\n|:---------------------|:-----:|:----------------|-----------|\n| Intel Core i7-13700K | ~1M   | Windows 11 23H2 | pre-1.0.0 |\n| AMD Ryzen 9 7950X    | ~920k | Fedora Linux 42 | pre-1.0.0 |\n| AMD Ryzen 7 7800x3d  | ~570K | Fedora Linux 42 | pre-1.0.0 |\n| AMD Ryzen 5 7600X    | ~500K | Debian Linux 12 | pre-1.0.0 |\n| Apple M1             | ~280k | macOS 26        | pre-1.0.0 |\n| lx2160a A72          | ~143K | Fedora Linux 42 | pre-1.0.0 |","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmengdotzip%2Fsleipnir","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmengdotzip%2Fsleipnir","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmengdotzip%2Fsleipnir/lists"}
