Some properties for processors are marked as sensitive and should be encrypted. These following properties will be used to encrypt the properties while in use by MiNiFi. This will currently not be used to encrypt properties in the config file.

keyThis is the password used to encrypt any sensitive property values that are configured in processors. By default, it is blank, but the system administrator should provide a value for it. It can be a string of any length, although the recommended minimum length is 10 characters. Be aware that once this password is set and one or more sensitive processor properties have been configured, this password should not be changed.
algorithmThe algorithm used to encrypt sensitive properties. The default value is PBEWITHMD5AND256BITAES-CBC-OPENSSL.
providerThe sensitive property provider. The default value is BC.
