Use MADCert to create root and intermediate Certificate Authorities, issue user and server certificates, etc for testing purposes.
MADCert is a cross-platform tool that consists of a certificate generator, a file system certificate manager, and a command line interface.
MADCert does not require openssl or any other programs to be installed in the Operating System.
Both Node.js and CLI examples are provided below.
To add MADCert to your project:
npm install madcert
var madcert = require("madcert")
-
Create a Certificate Authority (CA)
madcert.createCACert("Test Root CA", {validFrom: "2019-08-08", validTo: "2024-08-09"})
-
Create an Intermediate CA (Root CA must exist)
madcert.createIntermediateCACert("Test CA","rootCA", {validFrom: "2019-08-08", validTo: "2024-08-09"});
-
Create a Server Certificate (CA must exist)
madcert.createServerCert("Test Server", "test-ca", false, {validFrom: "2019-08-08", validTo: "2024-08-09"});
-
Create a localhost Server Certificate (CA must exist)
madcert.createServerCert("localhost", "test-ca", true, {validFrom: "2019-08-08", validTo: "2024-08-09"}); Note: A subject alternative name is automatically added to the generated certificate. See ENVIRONMENT above.
-
Create a User Certificate with CN=test-user (CA must exist)
madcert.createUserCert("test-user", "test-ca", {commonName: "test-user", organizationalUnits: ["SECURITY", "A456"], organizations: ["Some Organization"], country: "US", validFrom: "2019-08-08", validTo: "2024-08-09"});
-
Create a User Certificate CN=Alice Example (CA must exist)
madcert.createUserCert("Alice Example", "test-ca", {commonName: "Alice Example", organizationalUnits: ["SECURITY", "A456"], organizations: ["Some Organization"], country: "US", validFrom: "2019-08-08", validTo: "2024-08-09"});
-
List CA Certificates
madcert.listCACerts();
-
List Server Certificates
madcert.listServerCerts();
-
List User Certificates
madcert.listUserCerts();
-
Remove a CA Certificate
madcert.removeCACert("test-root-ca");
-
Remove a Server Certificate
madcert.removeServerCert("test-server", "test-ca");
-
Remove a User Certificate
madcert.removeUserCert("test-user", "test-ca");
-
Retrieve a CA Certificate as JSON
madcert.caCertToJSON("test-root-ca");
-
Retrieve a Server Certificate as JSON
madcert.serverCertToJSON("test-server", "test-ca");
-
Retrieve a User Certificate as JSON
madcert.userCertToJSON("test-user", "test-ca");
-
Convert name to a File Path Friendly Name
madcert.normalizeName("Test 123"); > 'test-123'
By default, the certs created by MADCert will be placed under a "pki" folder in the current working directory. MADCert commands also have the basePath
option to specify a top-level path where the certs will be stored. It is important that all of the certs are placed under the same top-level folder, so either run MADCert from within the same location each time or always provide the same basepath option when calling the MADCert commands.
-
Example Specifying the Certificate Storage Location (available on all certificate related commands)
madcert.createCACert("Test Root CA", {validFrom: "2019-08-08", validTo: "2024-08-09", basePath: "/some/path"})
-
General Syntax

By default, the certs created by MADCert will be placed under a "pki" folder in the current working directory. MADCert commands also have the --path
or -p
option to specify a top-level path where the certs will be stored. It is important that all of the certs are placed under the same top-level folder, so either run MADCert from within the same directory each time or always provide the same path option when calling the MADCert commands.
MADCERT_LH_SUBJECT_ALT_DNS_NAME
- Only used when creating a localhost server certificate (--localhost true
). When generating a localhost server certificate, MADCert will add a subject alternative DNS name to the certificate. This environment variable can be used to specify the subject alternative DNS name that will be added. If this environment variable is not set, then the host name will be used.
