Get Started

JAVA_HOME

Set the environment variable JAVA_HOME to point to root directory of the to the JRE/JDK installation.

CA Server and OCSP Responder

Download the binaries xipki-ca-<version>.zip, xipki-ocsp-<version>.zip and xipki-cli-<version>.tar.gz from releases.

Only if you want to use the development version, build it from source code as follows.

Get a copy of project code

git clone https://github.com/xipki/xipki

Build the project

In folder xipki
```
mvn clean install -DskipTests
```
Then you will find the following binaries:
- DB Tool: assembles/xipki-dbtool/target/xipki-dbtool-<version>.zip
- CA: assembles/xipki-ca/target/xipki-ca-<version>.zip
- OCSP: assembles/xipki-ocsp/target/xipki-ocsp-<version>.zip
- CLI (Command Line Interface): assembles/xipki-cli/target/xipki-cli-<version>.tar.gz

Install DB Tool

Unpack the binary xipki-dbtool-<version>.zip.
If you use database other than PostgreSQL, MariaDB and MySQL, you need to get the JDBC driver and copy it to the directory lib/jdbc.

Install CA Server

Unpack the binary xipki-ca-<version>.zip and install CA as described in the unpacked README file.

Install OCSP Responder

Note that CA and OCSP can be installed in the same servlet container.

Unpack the binary xipki-ocsp-<version>.zip and install OCSP responder as described in the unpacked README file.

Install Command Line Interface

Unpack the binary xipki-cli-<version>.tar.gz
Adapt the CMP client configuration xipki/cmpclient/cmpclient.json
If you get "java.lang.ClassNotFoundException: <jdbc class>", please copy the missing JDBC driver jar to the directory lib/ext.

Configure PKCS#11 device (optional)

This step is only required if the real PKCS#11 device instead of the emulator is used.

Copy xipki/security/example/pkcs11-hsm.json to xipki/security/pkcs11.json, and adapt the PKCS#11 configuration.

Configure how to handle SSL client certificate (optional)

This step is only required if the CA is behind a reverse proxy apache httpd.

Add the java property org.xipki.reverseproxy.mode
```
-Dorg.xipki.reverseproxy.mode=APACHE
```
configure the proxy to forward the headers via mod_proxy with the following configuration

# Require SSL Client verification
SSLVerifyClient		require

#initialize the special headers to a blank value to avoid http header forgeries 
RequestHeader set SSL_CLIENT_VERIFY  "" 
RequestHeader set SSL_CLIENT_CERT  "" 

<Location / >
 RequestHeader set SSL_CLIENT_VERIFY "%{SSL_CLIENT_VERIFY}s"
 RequestHeader set SSL_CLIENT_CERT "%{SSL_CLIENT_CERT}s"
 ...
</Location>

  * [Jetty: Tricks to do client certificate authentications behind a reverse proxy](http://www.zeitoun.net/articles/client-certificate-x509-authentication-behind-reverse-proxy/start)

Setup CA Server and OCSP Responder

Start the servlet container
HSM devices of Thales, e.g. nCipher, can use Thales preload to manage the PKCS#11 sessions. In this case, the servlet container should be started as follows

preload <start script>

Setup CA in CLI
- Start CLI. bin/karaf
- Setup CA
  - In case of using new keys and certificates, in CLI:
    source xipki/ca-setup/cacert-none/setup-*.script where * is place holder.
  - In case of using existing keys and certificates, in CLI:
    source xipki/ca-setup/cacert-present/setup-*.script where * is place holder.
  - If you wish to add the SCEP support, in CLI:
    source xipki/ca-setup/setup-scep.script.
- Verify the installation, execute the command in CLI:
  ca-info myca1

Enroll/Revoke Certificate and Get CRL via Shell (optional)

The following shell script demonstrates how to enroll and revoke certificates, and how to get the current CRL: <CLI_ROOT>/xipki/client-script/rest.sh

Note that this script tells CA to generate real certificates. DO NOT use it in the production environment.

Enroll/Revoke Certificate

SCEP
Using any SCEP client. XiPKI provides also a SCEP client.

The binary xipki-cli-<version>.tar.gz contains an example script in the folder xipki/client-script. It can be executed in the CLI as follows:
- source xipki/client-script/scep-client.script
XiPKI CLI XiPKI CLI provides commands to enroll and revoke certificates via CMP.

The binary xipki-cli-<version>.tar.gz contains an example script in the folder xipki/client-script. It can be executed in the CLI as follows:
- source xipki/client-script/cmp-client.script
REST API
The shell script xipki/client-script/rest.sh of the xipki-cli demonstrates the use of REST API.

The binary xipki-cli-<version>.tar.gz contains an example script in the folder xipki/client-script. It can be executed in the CLI as follows:
- source xipki/client-script/rest-client.script

CLI Commands

Please refer to commands.md for more details.
