add-user utility FIPS comliance

Does anyone know the algorithm/compliance inherent in the add-user utility when it adds a user/password to application-users.properties file?

For example:

./add-user joe password

In the *.properties file you see

joe=

What is the process/algorithm in use to convert "password" to "" and is that process/algorithm FIPS 140-2 compliant?
