Inspired by wireguard-vanity-address "faster algorithm", this tool searches for a WireGuard Curve25519 keypair with a base64-encoded public key that has a specified prefix.
Install the tool locally and run:
$ go install github.com/AlexanderYastrebov/wireguard-vanity-key@latest
$ wireguard-vanity-key -prefix=2025

$ go run . -prefix=2025or use Docker image:
$ docker pull ghcr.io/alexanderyastrebov/wireguard-vanity-key:latest
$ docker run ghcr.io/alexanderyastrebov/wireguard-vanity-key:latest -prefix=2025The tool checks ~18'000'000 keys per second on a test machine:
