If you want to get a blockchain gateway certificate, there are a few things you need to do. First, you need to have a blockchain gateway. You can get one by setting up a node or by using a hosted service. Second, you need to generate a certificate signing request (CSR). This can be done using OpenSSL. Finally, you need to submit the CSR to a Certificate Authority (CA).
A blockchain gateway is a node that allows you to connect to a blockchain network. A node can be either a full node or a light node. A full node stores the entire blockchain and processes all transactions. A light node only stores a small portion of the blockchain and relies on full nodes for processing transactions.
A hosted service is a type of node that is hosted by a third-party provider. Hosted services are convenient because they allow you to connect to a blockchain network without having to set up your own node.
Once you have a blockchain gateway, you need to generate a CSR. A CSR is a file that contains your public key and your identity information. Your identity information includes your name, your email address, and your organization name.
To generate a CSR, you need to use OpenSSL. OpenSSL is a command-line tool that is used for creating cryptographic keys and certificates. To generate a CSR, you need to first generate a private key. You can do this by running the following command:
openssl genrsa -out private.key 2048
This command will generate a private key file called “private.key”. Next, you need to generate a CSR file. You can do this by running the following command:
openssl req -new -key private.key -out csr.pem
This command will generate a CSR file called “csr.pem”. The CSR file contains your public key and your identity information.
Finally, you need to submit the CSR to a CA. A CA is an organization that verifies your identity and issues certificates. There are many different CAs, but we recommend using Let’s Encrypt. Let’s Encrypt is a free, open, and automated CA.
To submit your CSR to Let’s Encrypt, you can use the certbot tool. Certbot is a command-line tool that automates the process of obtaining and renewing certificates from Let’s Encrypt. To use certbot, you need to first install it. You can do this by running the following command:
sudo apt-get install certbot
Once certbot is installed, you can use it to submit your CSR. To do this, you need to run the following command:
sudo certbot certonly –csr csr.pem
This command will
