Jasypt support for Apache Karaf

This bundle is a helper for Jasypt (http://www.jasypt.org) running on Apache Karaf (http://karaf.apache.org) OSGi environment. The following features are added:

• register default StringEncryptor service that is used also by PAX-JDBC config (https://ops4j1.jira.com/wiki/display/PAXJDBC/Pax+JDBC)
• provide Apache Karaf console command to encrypt/decrypt text values or calculate/validate digests

Usage

• install feature: jasypt-encryption
• drop bundle into deploy/ directory of Apache Karaf container
• set environment variable (ENCRYPTION_PASSWORD by default) for encryption password

$ KARAF_HOME/bin/karaf -DENCRYPTION_PASSWORD=password

• configure default StringEncryptor (not created without configuration!)
  • create hu.blackbelt.karaf.jasypt.services.DefaultStringEncryptorConfig.cfg configuration file in deploy/ directory
  • or create configuration using WebConsole (all options are displayed automatically)
• (optional) encrypt password (using Karaf command) and replace password in DBCP2 configuration files

...
password=ENC(encrypted_password)
