### [System Requirements](#system-requirements)

- Java 21

- Maven 3

First install Java 21 with a package manager

and then export the correct the `JAVA_HOME`. For example on macOS:

```bash

export JAVA_HOME=/Library/Java/JavaVirtualMachines/openjdk-21.jdk/Contents/Home/

```

### Usage 

Create private / public keypair (always use 2048 bit modulus)

```

openssl genrsa -traditional -out private_key.pem 2048

openssl rsa -pubout -in private_key.pem -out public_key.pem

```

Convert private key to pkcs8 format in order to import it from Java

```

openssl pkcs8 -topk8 -in private_key.pem -inform pem -out private_key_pkcs8.pem -outform pem -nocrypt

```
