PGP decryption - private key file in camel-crypto component

Issue

• We are using camel-crypto feature to do PGP decryption. The keyFileName must be a classpath variable resources or a file on the file system http://camel.apache.org/crypto.html - PGPDataFormat Options

• Is it possible to point the keyFileName to another source than file: (e.g. using a specific URL handler) ? What are the other options than storing the private key on the file system?
