Crate salsa_simple 

Vendored XSalsa20 stream cipher implementation with serde support.

This is a custom implementation of the XSalsa20 stream cipher algorithm that provides serialization support via serde, which is required for persisting P2P network connection state in the Redux state machine.

Why vendored?

The external salsa20 crate (v0.10.2) does not provide serde support for serializing/deserializing cipher state. This is needed for:

• Persisting P2P pnet encryption state across restarts
• State snapshots in the Redux architecture
• Debugging and inspection capabilities

Implementation

This implementation manually implements the XSalsa20 algorithm and adds Serialize and Deserialize derives. It is tested against the external salsa20 crate (used as a dev-dependency) to ensure correctness.

Usage

Used in p2p/src/network/pnet/ for P2P private network encryption, providing encrypted communication between peers with serializable state.
