Method set_encryption_key

nodedb-wal/src/writer.rs:182–184

Set the encryption key. When set, all subsequent records will have their payloads encrypted with AES-256-GCM. Writes the 16-byte WAL segment preamble at the current file offset. Must be called before the first `append`. Calling it after records have already been written to this file returns an error.

        self.set_encryption_ring(crate::crypto::KeyRing::new(key))
