Mirror Maker: supplying broker properties with SSL password encrypted

Question

Is there a way to supply the consumer.config/producer.config property files having encrypted SSL password? I don't want to store the passwords in plaintext format in the filesystem

bin/kafka-run-class.sh kafka.tools.MirrorMaker --consumer.config sourceCluster1Consumer.config --consumer.config sourceCluster2Consumer.config --num.streams 2 --producer.config targetClusterProducer.config --whitelist=".*"
