# ePassport Certificates

ePassports, defined under ICAO Doc 9303, embed chips that store identity and biometric information. To secure this data, countries establish a **Public Key Infrastructure (PKI)** consisting of a Country Signing Certificate Authority (CSCA) and Document Signer Certificates.

emCA supports issuing these certificates, enabling Basic Access Control (BAC) and Extended Access Control (EAC) mechanisms. This ensures authenticity of travel documents, protects biometric data, and facilitates interoperability across borders.

How to configure, create, and issue ePassport Certificates in emCA will be published shortly.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://emca.emudhra.com/advanced-capabilities/epassport-certificates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
