Warning
While VaniSSH is designed to be safe and uses OpenSSL for key generation, this tool has not been thoroughly audited. Other vanity key generators have had vulnerabilities in the past, such as the Profanity vulnerability found by 1inch Network. Know the risks before using this tool, especially for production use.
VaniSSH is a simple tool for generating vanity SSH public keys that start, contain, or end with specified strings.
Usage: vanissh [OPTIONS]
Generate vanity SSH public keys that start/end with specified strings.
Options:
-p, --prefix PREFIX Desired prefix for the base64 public key
-s, --suffix SUFFIX Desired suffix for the base64 public key
-c, --contains STRING String that must appear anywhere in the base64 public key
-j, --threads NUM Number of threads to use (default: auto)
-o, --output FILE Output private key to file (default: stdout)
-i, --ignore-case Case-insensitive matching
-h, --help Show this help message
Notes:
- At least one of --prefix, --suffix, or --contains must be specified.
- Ed25519 public keys will always start with 'AAAAC3NzaC1lZDI1NTE5AAAAI',
which will be skipped when matching prefixes.
- The prefixes have a limited character set; not all characters are possible.
Examples:
vanissh -s TEST
vanissh -c 1337 -i
vanissh -p abc -i -o id_ed25519The following dependencies are required to build this project:
- C++23 compatible compiler
- Meson 1.1 or later
- libssh development libraries
- just (optional)
- Ninja (optional)
Arch Linux:
sudo pacman -Syu base-devel meson libssh clang ninja justDebian/Ubuntu:
sudo apt update
sudo apt install meson libssh-dev clang ninja-build justRed Hat/Fedora:
sudo dnf install meson libssh-devel clang ninja-build justIf Clang, Ninja, and just are installed, you can simply run:
justAlternatively, you can use Meson directly:
CXX=clang++ meson setup build --reconfigure \
--buildtype=release \
-Denable_native=true \
-Denable_fast_math=true
meson compile -C buildThe compiled binary will be located at build/vanissh.
