Encrypting LDAP and Database Passwords in MMC
The Management Console allows you to encrypt, out of the box, the following passwords used by MMC:
Database for environment data
Database for tracking data (Business Events)
LDAP password for MMC access to LDAP server
Previous versions of MMC required you to download an external library in order to encrypt the passwords, and to alter MMC configuration files in order to modify Java beans. In MMC, all you need to do is encrypt the password by running the provided script, and include the encrypted result in the relevant configuration file.
MMC stores passwords in configuration files, in plain text by default. In this scenario, an attacker with access to the filesystem where MMC resides could easily read the stored passwords. Encrypting the passwords allows you to avoid this security risk.
MMC uses the Jasypt encryption library for password encryption. You encrypt your password by running a script included in the MMC installation, as explained below.
To encrypt the password, run the appropriate script in your system’s terminal:
The script accepts several parameters, in the form
The value to encrypt. This is the actual LDAP or database password you wish to encrypt.
The string used for encrypting
(Optional.) The algorithm to use for encryption.
./encrypt.sh input=mypassword password=mykey algorithm=PBEWithMD5AndDES
For example, if running MMC on Tomcat, you can modify the

When you run the script, it will show the encrypted password on standard output, as shown in the example below.

Copy the encrypted output (the last line displayed above) and store it in a convenient location, such as a text file of your choosing. You will need to copy this value to the appropriate configuration file, as explained in the next section.

MMC stores passwords in the files and directories listed below:
Databases for persistent and tracking data:
databases directory contains one configuration file per supported database engine (see note below). There are two types of configuration files:
Files for supported database engines to store MMC persistent data (created alerts, deployments, etc.) These files are named in the format
mmc-<database engine name>.properties. For example,
Files for supported database engines to store transaction data (Business Events). These files are named in the format
tracking-persistence-<database engine name>.properties. For example,

By default, MMC stores persistent and transaction data on internal databases. However, you can store this data on external databases (see Persisting MMC Data On External Databases for details and supported database servers). If you are using MMC’s internal databases, in order to encrypt your password you will need to modify the following configuration files:
For each file that you need to modify, open it and locate one of the following lines, according to the type of data whose password you wish to encrypt:
For the persistent data password:
For the transaction data password:
For the LDAP password:
Comment the line by adding a hash symbol (#) to the beginning of the line, for example:
Add a new line with the variable declaration (in this example,
env.password for the password for environment data) and the encoded value of your password in the following format:
ENC("<your encoded password>")
