Package io.helidon.security.tools.config

Class SecureConfigFilter

java.lang.Object

io.helidon.security.tools.config.SecureConfigFilter

All Implemented Interfaces:

io.helidon.config.spi.ConfigFilter

public final class SecureConfigFilter
extends java.lang.Object
implements io.helidon.config.spi.ConfigFilter

Provides possibility to decrypt passwords from configuration sources. Configuration can be used to enforce encryption (e.g. we will fail on clear-text value).

Password in properties must be stored as follows:

• ${AES=base64} - encrypted password using a master password (must be provided to Prime through configuration, system property or environment variable)
• ${RSA=base64} - encrypted password using a public key (private key must be available to Prime instance, its location must be provided to prime through configuration, system property or environment variable)
• ${ALIAS=alias_name} - reference to another property, that is encrypted
• ${CLEAR=text} - clear-text password. Intentionally denoting this value as a protectable one, so we can enforce encryption (e.g. in prod)

Example:

 google_client_secret=${AES=mYRkg+4Q4hua1kvpCCI2hg==}
 service_password=${RSA=mYRkg+4Q4hua1kvpCCI2hg==}
 another_password=${ALIAS=service_password}
 cleartext_password=${CLEAR=known_password}
