Properties Files

Values in properties files can be encrypted. Let's say you have a property myurl in your local.properties which depends on a password and you would like to encode the password Password123456.

1
myurl=http://blah?pass=Password123456&user=steve

  1. Under the scripts directory, use the tools.sh (tools.bat for Windows) to create a 256-bit strength key (feel free to adjust the strength).

    1
    ./tools.sh --aes_generate /opt/ami/secret.aes 256

    1
    ./tools.bat --aes_generate /opt/ami/secret.aes 256

  2. Add this option to your start.sh so that AMI knows where the secret key for decoding encrypted properties is located

    1
    -Dproperty.f1.properties.secret.key.files=/opt/ami/secret.aes

    1
    -Dproperty.f1.properties.secret.key.files=C:/ami/amione/secret.aes

  3. Using the same tools.sh, Encode the password and copy the output text into your clipboard

    1
    ./tools.sh --aes_encrypt /opt/ami/secret.aes Password123456

    1
    ./tools.bat --aes_encrypt C:/ami/amione/secret.aes Password123456

    Example encoded password:

    1
    fYjHz8Dr4o7XjZcOd1BhtKzV9U5MpZMpTyGlu-mpheL4qV-ZX-yUads

  4. Change your local.properties file to use the encrypted value instead, by enclosing with ${CIPHER: ... }

    1
    myurl=http://blah?pass=${CIPHER:fYjHz8Dr4o7XjZcOd1BhtKzV9U5MpZMpTyGlu-mpheL4qV-ZX-yUads}&user=steve

  5. Restart AMI

In the AmiOne.log you'll see that the value for the myurl property is substituted with ***** for security purposes.

You can see the password listed in the user interface by going to Dashboard -> Session Variables. You can also decrypt using tool.sh by running:

1
./tools.sh --aes_decrypt /opt/ami/secret.aes fYjHz8Dr4o7XjZcOd1BhtKzV9U5MpZMpTyGlu-mpheL4qV-ZX-yUads

1
./tools.bat --aes_decrypt C:/ami/amione/secret.aes fYjHz8Dr4o7XjZcOd1BhtKzV9U5MpZMpTyGlu-mpheL4qV-ZX-yUads
