AppDynamics agents store various types of credential information on disk, including:

  • Controller account access key
  • Controller keystore/agent truststore password
  • Proxy server password

For environments where security policies require you to secure credentials stored on disk, you can use the Secure Credential Store to encrypt credentials for use in agent configuration.

Two components comprise the Secure Credential Store:

  • scs-tool.jar: A utility to create the secure credential store, encrypt credentials, and obfuscate the credential store password
  • Secure credential keystore: A keystore for the secret encryption key

The secure credential store utility encrypts plain text using the strongest encryption available according to the system's encryption jurisdiction policy.

For the .NET Agent, see Encrypt Credentials in .NET Agent Configuration.

Required: Update Agent Properties


After you set up the Credential Keystore, you must specify the following settings:

Analytics Agent

In Analytics Agent Properties:


Java, Machine, and Database Agents

In each agent's respective properties (Java Agent Properties, Machine Agent Properties, Database Agent Properties):

  • <controller-ssl-enabled>
  • <controller-keystore-filename>
  • <controller-keystore-password>

Initialize the Secure Credential Store 

Before you can encrypt or obfuscate passwords, you must run the secure credential store utility to create the keystore for your secret encryption key. The agent distribution includes the secure credential store utility in the following locations:

  • Java Agent: <javaagent_home>/verX.X.X.X/utils/scs/scs-tool.jar
  • Machine Agent: <machine_agent_home>/lib/secure-credential-store-tool-
  • Database Agent: <database_agent_home>/lib/scs-tool.jar
  • Analytics Agent: <analytics_agent_home>/bin/tool/scs-tool.jar

Run the secure credential store utility generate_ks command with the following parameters:

  • filename: Absolute path where the utility will create the secure credential keystore. Use this path for <credential-store-filename> in agent configuration.
  • storepass: The secure credential keystore password. Use the obfuscated version of this password as the value for <credential-store-password> in agent configuration.

For example:

/<full path to application JRE>/bin/java -jar ./scs-tool.jar generate_ks -filename '/opt/appdynamics/secretKeyStore' -storepass 'MyCredentialStorePassword'

The secure credential store utility confirms it created and initialized the keystore:

Successfully created and initialized new KeyStore file: /opt/appdynamics/secretKeyStore
Verification - New KeyStore file: /opt/appdynamics/secretKeyStore is properly initialized.


Encrypt Passwords

To encrypt passwords using the secure credential store utility, run the encrypt command with the following parameters:

  • filename: Absolute path to the secure credential keystore file.
  • storepass: Password for the secure credential keystore. You can use either a plain-text password or a password that has been obfuscated as described in the following section. 
  • plaintext: Any plain text to encrypt. For instance, account access key or password.

Here is an example using a plain-text —passwordthe -storepass argument—for the secure credential keystore:

/<full path to application JRE>/bin/java -jar ./scs-tool.jar encrypt -filename '/opt/appdynamics/secretKeyStore' -storepass 'MyCredentialStorePassword' -plaintext 'MyAccessKeyOrPassword'

Here is the same example using an obfuscated password:

/<full path to application JRE>/bin/java -jar ./scs-tool.jar encrypt -filename '/opt/appdynamics/secretKeyStore' -storepass 's_gsnwR6+LDch8JBf1RamiBoWfMvjjipkrtJMZXAYEkw8=' -plaintext 'MyAccessKeyOrPassword'


The secure credential store utility writes out an encrypted password for use in agent configuration files:



Obfuscate the Secure Credential Store Password

In order to access the secret key in the secure credential keystore, the agent needs the obfuscated credential store password. Run the secure credential store utility obfuscate command with the following parameter:

  • plaintext: The plain text secure credential keystore password.

For example:

/<full path to application JRE>/bin/java -jar /opt/appdynamics/scs-tool.jar obfuscate -plaintext 'MyCredentialStorePassword'

The secure credential store utility writes out an obfuscated password for use in the <credential-store-password> in agent configuration. For example:


Encrypt a plain text property

After you obfuscate the secure credential store password, you can encrypt plain text properties. For example, the following demonstrates how to encrypt properties in the analytics agent:

$ /<full path to application JRE>/bin/java -jar scs-tool.jar encrypt -filename /opt/appdynamics/secretKeyStore -storepass 'Welcome' -plaintext 'MyAccountAccessKey'

This generates an encrypted credential, such as:


Sample Agent Configuration

The following example demonstrates the agent configuration properties for the Secure Credential Store. For more information see the agent-specific configuration property documentation.

Java Agent Configuration

<?xml version="1.0" encoding="UTF-8"?>
    <!-- Encrypted account access key -->
    <!-- Encrypted Controller keystore / agent trust store password -->
    <!-- Enable the Secure Credential Store -->
    <!-- Path to they secure credential keystore -->
    <!-- Obfuscated secure credential keystore password -->

Analytics Agent Configuration

Encrypt Data on the Analytics Agent

You can encrypt any data on the analytics agent using secure://<your-encrypted-credentials>. You can encrypt data in the Analytics Agent Properties file or System Properties. The following example demonstrates how to encrypt http.event.accessKey in the Analytics Agent Properties file.
