VCert Java

VCert is a Java library, SDK, designed to simplify key generation and enrollment of machine identities (also known as SSL/TLS certificates and keys) that comply with enterprise security policy by using the Venafi Platform or Venafi Cloud.

Compatibility

VCert releases are tested using the latest version of Trust Protection Platform and Venafi Cloud. The latest VCert release should be compatible with Trust Protection Platform 17.3 or higher based on the subset of API methods it consumes. Token Authentication requires 19.2 or higher; for earlier versions, username/password authentication (deprecated) applies.

Installation

VCert-Java releases are published to the Maven Central Repository making them easy to use with Java projects built using popular tools. To build using Maven, start by identifying the version number of the latest release in the Maven Central Repository. Then add the following dependency configuration to your Java project's pom.xml, replacing "0.0.1" with the appropriate version:

<dependency>
  <groupId>io.github.venafi</groupId>
  <artifactId>vcert-java</artifactId>
  <version>0.0.1</version>
</dependency>

Config snippets for building using other tools are listed on the release page in the Maven Central Respository. For example, this page shows snippets for VCert-Java v0.6.2.

Usage

Instantiate a client for Trust Protection Platform using token authentication with an existing access token:

final Authentication auth = Authentication.builder()
        .accessToken("9PQwQeiTLhcB8/W3/z2Lbw==")
        .build();

final Config config = Config.builder()
        .connectorType(ConnectorType.TPP_TOKEN)
        .baseUrl("https://tpp.venafi.example")
        .credentials(auth)
        .build();

final VCertTknClient client = new VCertTknClient(config);

Or instantiate a client for Venafi Cloud:

final Authentication auth = Authentication.builder()
        .apiKey("aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee")
        .build();

final Config config = Config.builder()
        .connectorType(ConnectorType.CLOUD)
        .build();

final VCertClient client = new VCertClient(config);
client.authenticate(auth);

Then use your client to request certificates:

• For Trust Protection Platform, the zone format is the DN of a policy with or without the "\VED\Policy" prefix (e.g. "\VED\Policy\Certificates\VCert" or simply "Certificates\VCert")
• For Venafi Cloud, the zone format is the name of an OutagePREDICT Application and the API Alias of an Issuing Template assigned to it delimited by a single backslash character (e.g. "My Application\My CIT")

System.out.println(pemCollection.pemCertificate());

To specify the desired validity when requesting a certificate from Trust Protection Platform or Venafi Cloud, use validityHours():

CertificateRequest certificateRequest = new CertificateRequest().subject(
        new CertificateRequest.PKIXName()
                .commonName("vcert-java.venafi.example"))
        .dnsNames(Arrays.asList("alfa.venafi.example", "bravo.venafi.example", "charlie.venafi.example"))
        .keyType(KeyType.RSA)
        .validityHours(720)
        .issuerHint("MICROSOFT"); // needed for TPP when the CA is "DIGICERT", "ENTRUST", or "MICROSOFT"

To assign Custom Field values when requesting a certificate from Trust Protection Platform, construct a list of CustomField objects (name/value) and then add them to the request using customFields():

List<CustomField> fields = new ArrayList<CustomField>();
fields.add(new CustomField("Cost Center", "ABC123"));
fields.add(new CustomField("Environment", "Production"));
fields.add(new CustomField("Environment", "Staging"));

CertificateRequest certificateRequest = new CertificateRequest().subject(
        new CertificateRequest.PKIXName()
                .commonName("vcert-java.venafi.example"))
        .dnsNames(Arrays.asList("alfa.venafi.example", "bravo.venafi.example", "charlie.venafi.example"))
        .keyType(KeyType.RSA)
        .customFields(fields);

You can also instantiate a client for Trust Protection Platform using token authentication without an existing token by providing a username/password. Such a token is generally for short-term or temporary use and as such should be revoked upon completion of your tasks:

final Authentication auth = Authentication.builder()
        .user("local:apiuser")
        .password("password")
        .build();

final Config config = Config.builder()
        .connectorType(ConnectorType.TPP_TOKEN)
        .baseUrl("https://tpp.venafi.example")
        .build();

final VCertTknClient client = new VCertTknClient(config);
client.getAccessToken(auth);

///// REQUEST, RENEW, AND/OR REVOKE CERTIFICATES...

client.revokeAccessToken();

👎 To instantiate a client for Trust Protection Platform using deprecated username/password authentication:

final Authentication auth = Authentication.builder()
        .user("local:apiuser")
        .password("password")
        .build();

final Config config = Config.builder()
        .connectorType(ConnectorType.TPP)
        .baseUrl("https://tpp.venafi.example/vedsdk")
        .build();

final VCertClient client = new VCertClient(config);
client.authenticate(auth);

Prerequisites for using with Trust Protection Platform

1. A user account that has an authentication token with "certificate:manage,revoke" scope (i.e. access to the "Venafi VCert SDK" API Application as of 20.1) or has been granted WebSDK Access
2. A folder (zone) where the user has been granted the following permissions: View, Read, Write, Create, Revoke (for the revoke action), and Private Key Read (for the pickup action when CSR is service generated)
3. Policy applied to the folder which specifies:
   1. CA Template that Trust Protection Platform will use to enroll certificate requests submitted by VCert
   2. Subject DN values for Organizational Unit (OU), Organization (O), City (L), State (ST) and Country (C)
   3. Management Type not locked or locked to 'Enrollment'
   4. Certificate Signing Request (CSR) Generation not locked or locked to 'Service Generated CSR'
   5. Generate Key/CSR on Application not locked or locked to 'No'
   6. (Recommended) Disable Automatic Renewal set to 'Yes'
   7. (Recommended) Key Bit Strength set to 2048 or higher
   8. (Recommended) Domain Whitelisting policy appropriately assigned

The requirement for the CA Template to be assigned by policy follows a long standing Venafi best practice which also met our design objective to keep the certificate request process simple for VCert users. If you require the ability to specify the CA Template with the request you can use the TPP REST APIs but please be advised this goes against Venafi recommendations.

Prerequisites for using with Venafi Cloud

1. The Venafi Cloud REST API is accessible at https://api.venafi.cloud from the system where VCert will be executed.
2. You have successfully registered for a Venafi Cloud account, have been granted at least the OutagePREDICT "Resource Owner" role, and know your API key.
3. A CA Account and Issuing Template exist and have been configured with:
   1. Recommended Settings values for:
      1. Organizational Unit (OU)
      2. Organization (O)
      3. City/Locality (L)
      4. State/Province (ST)
      5. Country (C)
   2. Issuing Rules that:
      1. (Recommended) Limits Common Name and Subject Alternative Name to domains that are allowed by your organization
      2. (Recommended) Restricts the Key Length to 2048 or higher
      3. (Recommended) Does not allow Private Key Reuse
4. An OutagePREDICT Application exists where you are among the owners, and you know the Application Name.
5. An Issuing Template is assigned to the Application, and you know its API Alias.
