This guide will show you how to generate a Certificate Signing Request in a Node.js Web Server.<\/p>\n\n\n\n

You have two options to generate CSR.<\/strong><\/p>\n\n\n\n

    \n
  1. Automatic CSR Generation Tool<\/li>\n\n\n\n
  2. Make use of the Crypto Module.<\/li>\n<\/ol>\n\n\n\n

    Generating CSR on NodeJS is very easy & quick using our CSR generation tool<\/a>.<\/p>\n\n\n\n

    Steps to Generate CSR in Node.js using the Crypto Module:<\/h2>\n\n\n\n

    Generate a private key using the following code. The key will be required to generate the CSR.<\/p>\n\n\n\n

    const privateKey = crypto.createPrivateKey({\nmodulusLength: 2048,\npublicKeyEncoding: {\ntype: 'spki'\n},\nprivateKeyEncoding: {\ntype: 'pkcs1'\n}\n});\n<\/code><\/pre>\n\n\n\n
    Define your certificate details in an X509 name object; this includes basic information like common name (CN), country, organization, etc.<\/p>\n\n\n\n
    For example:<\/strong><\/p>\n\n\n\n
    const x509name = {\nCN: 'example.com',\nO: 'Example Org',\nC: 'IN'\n};<\/code><\/pre>\n\n\n\n
    Use the x509name object and private key to generate the CSR.<\/strong><\/p>\n\n\n\n
    const csr = crypto.createCSR({\nname: x509name,\nprivateKey\n});<\/code><\/pre>\n\n\n\n
    Convert the CSR string to PEM format; this is the standard format for CSRs. Use the following command:<\/strong><\/p>\n\n\n\n
    const csrPEM = crypto.CSR_to_PEM(csr);<\/code><\/pre>\n\n\n\n
    Your CSR PEM string is ready to be submitted to a certificate authority for signing and issuing an SSL certificate.<\/p>\n\n\n\n
    You can save the CSR PEM to a file using fs.writeFileSync() or any other file writing method.<\/p>\n\n\n\n
    That’s the basic process to generate a CSR in Node.js using the crypto module. <\/p>\n\n\n\n
