+(1) The seed file contains the NKey seed from which the streaming server can extract the public key and the private key used to sign the nonce sent by the NATS Server when accepting connections from the Streaming server. The file is read during the connection process and the key is used to sign but then wiped from memory. The file must contain the seed file with such format:
+```
+-----BEGIN USER NKEY SEED-----
+SU<rest of the seed>
+------END USER NKEY SEED------
