Rana 🐸

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.

Requirements:

1. You need Rust version 1.64 or higher to compile.

Compile and execute it:

To compile on Ubuntu/Pop!_OS/Debian, please install cargo, then run the following commands:

$ 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

  --difficulty <bits>   Enter the number of starting bits that should be 0.

  --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.

  --vanity-n <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.

```

Examples:

```bash $ cargo run --release -- --difficulty=20

$ cargo run --release -- --vanity=dead

$ cargo run --release -- --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.
