What is PeSIT Wizard?
PeSIT Wizard is a modern, fully open-source implementation of the PeSIT E file-transfer protocol, written in Rust. It ships as a single self-contained node — the pesitwizard binary — that both listens for incoming transfers and initiates outgoing ones, with a built-in web console and a REST API.
The PeSIT protocol
PeSIT (Protocole d'Échange pour un Système Interbancaire de Télécompensation) is the standard file-transfer protocol used by French banks and on the SIT network. PeSIT Wizard implements PeSIT E — the TLS-capable version — and is validated for interoperability against IBM Sterling Connect:Express 1.5.
See the protocol reference for the full feature list.
One node
A single process does everything:
- Listens for partners connecting in and receives or serves files (the server role).
- Initiates outgoing transfers to remote servers (the client role).
- Serves a web console at
/and two REST surfaces backed by one shared store.
There is no separate server, client or admin console to install, and no commercial edition — every feature is in the one binary under Apache-2.0.
What it can do
- Full PeSIT E: CRC, compression, segmentation, synchronisation points with windowing, restart / resynchronisation, text / binary record formats, EBCDIC translation, TLS and pre-connection.
- Partners, virtual files and listeners configured over REST or the console.
- Storage connectors (S3 / SFTP / local) backing virtual files.
- Certificates & PKI: a local CA, native HashiCorp Vault PKI, rotation, CRL and an OCSP responder.
- Clustering over NATS / JetStream with configuration replication and distributed schedules.
- Operations: Prometheus metrics, health probes, an audit log, and signed configuration backups.
