Please update documentation https://cloud.spring.io/spring-cloud-config/reference/html/ Regarding key decryption, the RSA example does not work, because: 1. the config changed from encrypt.keyStore to encryption.key-store, 2. there are some required RsaProperties to run. 3.indentation in the documentation might suggest it should be with a prefix spring.cloud.config.server (i.e. spring.cloud.config.server.encrypt.key-store) where it actually is top level encryption.key-store parameter, its especially confusing since flag to enable/disable is "spring.cloud.config.server.encrypt.enabled"
To ease up on tracking, its about the class org.springframework.cloud.config.server.config.EncryptionAutoConfiguration
