This is how to create a certificate using OpenSSL OpenSSL Certificate Authority

I tried with pem

This is my closed Issue can't create CSR from private key #244 GitHub

When I trying to generate a CSR

var csrOptions = {
    clientKey: '/root/ca/intermediate/private/client.key.pem',
    clientKeyPassword: '123456',
    hash: 'sha256',
    country: 'US',
    state: 'California',
    locality: 'Mountain View',
    organization: 'Alice Ltd',
    organizationUnit: 'Alice Ltd Web Services',
    commonName: 'pass:client',
}

pem.createCSR( csrOptions , function(err, csr) {
    if (err) {
        throw err
    } else {
        console.log(csr.clientKey)
        console.log(csr.csr)
    }

});

I get this error

After searching I get the error, clientKey took a key as a string, not a path

clientKey: '/root/ca/intermediate/private/client.key.pem',

clientKey: fs.readFileSync('/root/ca/intermediate/private/client.key.pem'),
