Apache Kerby

Apache Kerby, as an Apache Directory sub project, is a Java Kerberos binding. It provides a rich, intuitive and interoperable implementation, library, KDC and various facilities that integrates PKI, OTP and token (OAuth2) as desired in modern environments such as cloud, Hadoop and mobile.

The Initiatives/Goals

  • Aims as a Java Kerberos binding, with rich and integrated facilities that integrate Kerberos, PKI and token (OAuth2) for both client and server sides.
  • Provides client APIs at the Kerberos protocol level to interact with a KDC server through AS and TGS exchanges.
  • Provides a standalone KDC server that supports various identity backends including memory based, Json file based, LDAP based and even Zookeeper based.
  • Provides an embedded KDC server that applications can easily integrate into products, unit tests or integration tests.
  • Supports FAST/Preauthentication framework to allow popular and useful authentication mechanisms.
  • Supports PKINIT mechanism to allow clients to request tickets using x509 certificate credentials.
  • Supports Token Preauth mechanism to allow clients to request tickets using JWT tokens.
  • Supports OTP mechanism to allow clients to request tickets using One Time Password.
  • Provides support for JAAS, GSSAPI and SASL frameworks that applications can leverage.
  • Minimal dependencies, the core part is ensured to depend only on JRE and SLF4J, for easy use and maintenance.

KrbClient APIs

A Krb client API for applications to interact with KDC.
Please look at kerb-client for details.

Kadmin

Server side admin facilities.
Please look at kerb-admin for details.

KdcServer

Kerberos Server API.
Please look at kerb-server for details.

SimpleKdcServer

A simplified Kdc server. It can be imported by other project to work as a kdc server.
Please look at kerb-simplekdc for details.

ASN-1 support

A model driven ASN-1 encoding and decoding framework implemented with Java.
Please look at kerby-asn1 for details.

How to play with the standalone KDC

Please look at Kerby KDC for details.

Kerberos Crypto and Encryption Types

  • Implementing des, des3, rc4, aes, camellia encryption and corresponding checksum types
  • Interoperates with MIT Kerberos and Microsoft AD
  • Independent of Kerberos code in JRE, but relies on JCE

Similar to MIT krb5 encryption types:

Encryption TypeDescription
des-cbc-crcDES cbc mode with CRC-32 (weak)
des-cbc-md4DES cbc mode with RSA-MD4 (weak)
des-cbc-md5DES cbc mode with RSA-MD5 (weak)
des3-cbc-sha1 des3-hmac-sha1 des3-cbc-sha1-kdTriple DES cbc mode with HMAC/sha1
des-hmac-sha1DES with HMAC/sha1 (weak)

rc4The RC4 family: arcfour-hmac
camelliaThe Camellia family: camellia256-cts-cmac and camellia128-cts-cmac

Identity Backend

A standalone KDC server that can integrate various identity backends including:

  • MemoryIdentityBackend.
    • It is default Identity Backend, and no cofiguration is needed. This backend is for no permanent storage requirements.
  • JsonIdentityBackend.
    • It implemented by Gson which is used to convert Java Objects into their JSON representation and convert a JSON string to an equivalent Java object. A json file will be created in “backend.json.dir”. This backend is for small, easy, development and test environment.
  • MySQLIdentityBackend.
    • A backend based on MySQL.
  • ZookeeperIdentityBackend.
    • Currently it uses an embedded Zookeeper. In follow up it will be enhanced to support standalone Zookeeper cluster for replication and reliability. Zookeeper backend would be a good choice for high reliability, high performance and high scalability requirement and scenarios.
  • LdapIdentityBackend.
    • The Ldap server can be standalone or embedded using ApacheDS server as the backend. It is used when there is exist ldap server.
  • MavibotBackend.
    • A backend based on Apache Mavibot(an MVCC BTree library).

Network Support

  • Include UDP and TCP transport.
  • Default KDC server implementation.
    • The Networking Classes in the JDK is used.
  • Netty based KDC server implementation.
    • Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.
    • With better throughput, lower latency.

Tools

  • kinit:
    • Obtains and caches an initial ticket-granting ticket for principal.
  • klist:
    • Lists the Kerby principal and tickets held in a credentials cache, or the keys held in a keytab file.
  • kdcinit:
    • This is used to initialize and prepare all kinds of KDC side materials, like initializing concrete back end, setting up master keys, necessary principals (tgs, kadmin) and etc.
  • kadmin:
    • Command-line interfaces to the Kerby administration system.

Kerby Common Projects

  • kerby-asn1. A model driven ASN-1 encoding and decoding framework
  • kerby-config. A unified configuration API that aims to support various configuration file formats, like XML, INI, even Java Map and Properties.
  • kerby-util. Common utilities used by project.

Dependency

  • The core part is ensured to only depend on the JRE and SLF4J. Every external dependency is taken carefully and maintained separately.
  • Nimbus JOSE + JWT, needed by token-provider and TokenPreauth mechanism.
  • Netty, needed by netty based KDC server.
  • Zookeeper, needed by zookeeper identity backend.
