Mine public keys that can be used with nostr.
This is based on nip13 example.
Provide the desired difficulty or the vanity prefix as arguments. See below.
Using Cargo to install (requires ~/.cargo/bin to be in PATH)
bash
$ cargo install rana
To compile on Ubuntu/Pop!_OS/Debian, please install cargo, then run the following commands:
bash
$ sudo apt update
$ sudo apt install -y cmake build-essential
Then clone the repo, build and run:
bash
$ git clone https://github.com/grunch/rana.git
$ cd rana
$ cargo run --release
By default it will generate a public key with a difficulty of 10 but you can customize its difficulty or vanity prefix with the proper parameters.
Usage:
Options:
-d, --difficulty <DIFFICULTY>
Enter the number of starting bits that should be 0. [default: 10]
-v, --vanity <VANITY_PREFIX>
Enter the prefix your public key should have when expressed
as hexadecimal. This can be combined with --vanity-n,
but beware of extra calculations required. [default: ]
-n, --vanity-n <VANITY_NPUB_PREFIX>
Enter the prefix your public key should have when expressed
in npub format (Bech32 encoding).
This can be combined with --vanity, but beware of extra
calculations required. [default: ]
Examples:
```bash $ cargo run --release -- --difficulty=20
$ cargo run --release -- --vanity=dead
$ cargo run --release -- --vanity-n=rana ```
If you have it installed with cargo install:
```bash $ rana --difficulty=20
$ rana --vanity=dead
$ rana --vanity-n=rana ```
Keep in mind that you cannot specify a difficulty and a vanity prefix at the same time. Also, the more requirements you have, the longer it will take to reach a satisfactory public key.
