# eIDAS — Electronic Signatures

> FlexOrch detects electronic signature formats in documents.

## Overview

eIDAS (EU 910/2014) defines standards for electronic signatures. FlexOrch detects the presence of eIDAS-compliant signature formats in processed documents and records this in the execution metadata.

## Detected signature formats

| Format | Description                       |
| ------ | --------------------------------- |
| XAdES  | XML Advanced Electronic Signature |
| PAdES  | PDF Advanced Electronic Signature |
| CAdES  | CMS Advanced Electronic Signature |

## In the execution result

When an eIDAS signature is detected, the execution metadata includes:

```json theme={null}
{
  "eidas_detected": true,
  "eidas_formats": ["PAdES"],
  "eidas_note": "Document contains a PAdES electronic signature. Validity verification requires a qualified trust service provider (QTSP)."
}
```

<Warning>
  FlexOrch detects signature presence and format, but does not validate signature validity or certificate trust chains. Use a qualified trust service provider (QTSP) for legal signature validation.
