cert-base

Certificates management tool using openssl wrapper pem to create and sign certificates

To install npm install cert-base

Usage

Here we're going to create a CA cert, and then use it to sign a cert

/**
 * First we create a CA cert
 */
 
const cb = new CertBase({
  path: 'path/to/a/folder'
})
 
cb.createCACert('commonName_for_ca')
  .then(result => {
    console.log(result.key, result.cert)
  })
 
/**
 * Then we sign a cert using the CA cert
 */
 
cg.getCertByHost('commonName_for_hostname')
  .then(result => {
    console.log(result.key, result.cert)
  })

API Documentations

Constructor options

const cb = new CertBase({
  path: 'path/to/a/folder',
  subject: {
    country: 'CN',
    organization: 'CertBase',
    organizationUnit: 'CertBase Certification'
  },
  opensslPath: '/path/to/your/openssl'
})

where

• path is the folder path you want to store your certs and keys in, regard it as a cert base
• subject is the subject object used when creating CA cert or signing cert by hostname. The default settings is listed below
• opensslPath is the location of the openssl executable. This is because you may want to use a custom openssl version instead of the system default openssl executable which is the default value of this field

// subject default settings
{
  country: 'CN',
  organization: 'CertBase',
  organizationUnit: 'CertBase Certification'
}

For more subject options and documentations, check here. This is because pem is used inside this package to do all openssl works

Create a CA cert

cb.createCACert(commonName)
  .then(result => {
    // result object has 2 fields:
    //
    // key : the generated key content
    // cert: the generated cert content
  })

where

• commonName is the commonName field for the CA cert

Check if CA cert exist

cb.isCAExist()

returns true or false

Sign a cert by hostname

Before you call this method, you must have a ca cert generated, or an error will be thrown

cb.getCertByHost(hostname)
  .then(result => {})

where

• hostname is the commonName field for your cert

If you had the same hostname cert generated before, it will use that cert and won't generate a new one

List all self signed certs

cb.listSignedCerts().then(certs => {
  // certs is an array of signed domains
})

List all self signed certificates, certs is an array like this:

['www.google.com', 'github.com', ...]

Remove all certs

cb.removeAllCerts().then()

Removes everything inside the storage directory

Remove cert by hostname

cb.removeCert(hostname).then()

Removes a self signed cert with a given name

Remove all signed certs

cb.removeAllSignedCerts().then()

Removes all self signed certs(empty certs directory)

About how certs are stored

The certs are stored under the folder path the user give when calling the constructor function.

Strorage structure:

cert-path/
  ca/
    ca.crt
    ca.key
  certs/
    domain1/
      domain1.crt
      domain1.key
    domain2/
      domain2.crt
      domain2.key
    ...
