Generating an RSA Key Pair

This guide explains how to install OpenSSL (if needed), generate an RSA key pair, and copy the public key for uploading to the Dashboard.

Important

Never share your private key. Only the public RSA key should be uploaded to the Dashboard.

Option 1: Web Interface (Recommended)

The easiest way to generate your RSA key pair is using our dedicated web tool. No installation is required.

1. Go to https://rsa-tools.crypto-chief.com/.

2. Follow the instructions on the screen to generate a new key pair.

3. Download/Copy the Private Key and store it securely (you will not be able to see it again).

4. Copy the Public Key and paste it into the Dashboard.

Option 2: Command Line (Manual)

If you prefer to generate keys locally using your terminal, choose your operating system below.

Mac

Step 1: Check if OpenSSL is installed

1. Open Terminal.

2. Run:

openssl version

• If you see a version number, OpenSSL is installed.

• If you see an error, follow the installation steps below.

Step 2: Install OpenSSL (if not installed)

1. Install Homebrew (if not already installed):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

1. Install OpenSSL:

brew install openssl

1. Verify installation:

openssl version

Step 3: Generate the RSA key pair

openssl genrsa -out rsa_private.pem 2048
openssl rsa -in rsa_private.pem -pubout -out rsa_public.pem

Step 4: Copy the public key content

1. Display the public key:

cat rsa_public.pem

1. Copy everything, including:

-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----

1. Paste the copied content into Project Settings → RSA Key in the Dashboard.

Linux

Windows

Common mistakes

• ❌ Uploading the private key instead of the public key

• ❌ Copying the key without BEGIN / END lines

• ❌ Adding extra spaces or removing line breaks

• ❌ Storing private keys in repositories or client-side code
