# signum-vanity-address-generator

Vanity Address Generator for the Signum Blockchain Platform

Create your personalized Signum Address, like `S-BEER-XYBN-2G34-H98GT`

# How it works

> Prerequisites: [OpenJDK 11](https://openjdk.java.net/install/) installed

Download the jar file from the Github releases and run

`java -jar signum-vanity.jar --help`

```

Usage: signum-vanity [-hVw] [-o=] [-p=] -t=

Creates a vanity address for the Signum blockchain platform

  -h, --help                Show this help message and exit.

  -o, --timeout=   Timeout to cancel the search after x minutes passed

  -p, --position= The position for the vanity part from 1 to 4

  -t, --target=     The targeted vanity part

  -V, --version             Print version information and exit.

  -w, --words               Creates a BIP39 12 word passphrase

```

| Option | Description  | Required  | Default  |  

|---|---|---|---|

| -p  | The position in the address part where the target shall appear, starting with 1 and at maximum 4. Position 2 would be `S-xxxx-HERE-xxxx-xxxxx`   |  No | 1  | 

| -t  | The target string in the address which can be at maximum 4 characters, or 5 respectively for the last position (4). It must not contain the following chars `I 1 0 O `   |  Yes |   | 

| -w  | Creates a 12 word passphrase based on BIP39 word list | No | false  | 

| -o  | Defines a timeout in minutes.   | No | 30  | 

Example:

The following example _might_ generate the following address: `S-BEER-9U6Y-BS43-PL79A`

```bash 

java -jar signum-vanity.jar -t=BEER 

```

The following example _might_ generate the following address: `S-RT5V-765H-YTU6-5PACE`

and a twelve words passphrase, which stops searching after 15 minutes passed. 

```bash 

java -jar signum-vanity.jar -t=5PACE -p=4 -w -o=15

```

> Note that the generation can take a while (up to some minutes), especially when wanting 4 or 5 chars.

> The last part can only start with letters [2-9A-H]

# Security

The Vanity Address Generator uses a cryptographically secure (`SecureRandom`) randomized passphrase and checks if the resulting address meets the desired address pattern.

Each iteration a new random passphrase is being generated, such there is no predictable pattern for the addresses/passphrases.

The resulting passphrase is either based upon an 58 alphanumeric alphabet and has 80 characters, or creates a [BIP39](https://en.bitcoin.it/wiki/Seed_phrase) phrase.
