Encrypting passwords in server.xml
To add extra security to your Bamboo instance, you can encrypt passwords to configure Connectors in the Tomcat’s server.xml file.
Before you begin
This solution is an obfuscation that can be used to secure information such as passphrases used by Bamboo to access its local keystores and other secrets. This doesn’t assure real security. For example, though stored locally using an encrypted format, an Apache Reverse Proxy will send the proxy secret in clear-text to Bamboo when using the AJP protocol. An attacker could act like Bamboo to obtain the password.
To improve security, use HTTPS and secure the server where Bamboo resides.
Bamboo provides the following protocols that extend Tomcat protocols with support for password encryption.
|Tomcat protocol on which Bamboo protocol is based
|Attributes for which password encryption is supported
Encrypting a single password
- Go to
Run the following command:
java -jar atlassian-bamboo-tomcat-utils-<your bamboo version>.jar
Enter your password when prompted.
The encryption tool will generate two files:
encryptionKey.Move those files to a safe location. You can also rename the files if you want.
Encrypting multiple passwords for one Connector
If you want to encrypt more than one password for a single Connector, you must use the same encryption key for all passwords. After you encrypt you first password, use the generated
encryptionKey to encrypt the subsequent password by passing path to the key to the encryption tool:
java -jar atlassian-bamboo-tomcat-utils-*.jar /path/to/encryptionKey
The encryption tool will generate only the
Using encrypted passwords in Connector configuration
To use encrypted passwords in Connector configuration, you need to set up the following properties:
protocol- use on of the Bamboo protocols described above
bambooEncryptionKey- specify a path to the encryptionKey file
Then you can use path to a proper encryptedPassword file in place of plain text password in the Connector configuration.
For example, configuration of a
Http11Nio2 Connector with encrypted keystore and key passwords might look similarly to this:
Note that only one
bambooEncryptionKey is specified, and both
keyPass had to be encrypted with the same key.
