## Documentation

# Deploy and Host pfxsigner on Railway

[pfxsigner](https://github.com/knadh/pfxsigner) is an HTTP server (and CLI) for digitally signing PDFs with signatures loaded from PFX (PKCS #12) certificates.

## About Hosting pfxsigner

This template packages the `v0.4.0` Linux release. On start it generates a demo PFX (legacy PBE for Go pkcs12 compatibility) and default `props.json` on a volume at `/data`, then serves `POST /document` on port 8000. Replace the demo certificate with your own PFX for production signing.

## Common Use Cases

- HTTP API for PDF digital signatures
- Regulatory / document signing microservices
- Batch signing companion for document workflows

## Dependencies for pfxsigner Hosting

- Persistent volume — `/data` for cert.pfx and props.json
- Public domain — HTTP API on port 8000
- PFX certificate — demo cert is auto-generated; replace for real trust

### Deployment Dependencies

- [pfxsigner repository](https://github.com/knadh/pfxsigner)
- Release `pfxsigner_0.4.0_linux_amd64.tar.gz`

### Implementation Details

Set `PFX_PASSWORD` for the certificate export. Post multipart form fields `file` (PDF) and optional `props` (JSON) to `/document`.
