# Before you start

> Verify your environment meets the requirements for integrating Ascertia ADSS Server with CryptoHub.

*Verify your environment meets these requirements before proceeding. All prerequisites must be satisfied for a successful integration.*

## Supported hardware

* CryptoHub `7.0.3.x` or later

## Supported operating systems

* Linux
* Windows

## Required access

* Administrator access to the CryptoHub web interface (dual-control login)
* Administrator access to the Ascertia ADSS Admin Console
* Root or sudo access on the ADSS Server host machine

## Network and firewall

* Outbound TCP port **2001** from the ADSS Server host to the CryptoHub
* The CryptoHub must be reachable by FQDN or IP address from the ADSS Server host

<Warning>
  If your network uses TLS inspection or an SSL proxy, exempt traffic between the ADSS Server host and the CryptoHub. TLS inspection interferes with mutual TLS authentication and causes connection failures.
</Warning>

## Software requirements

* Ascertia ADSS Server **8.3.x** or later, installed and operational
* PostgreSQL (or another supported database) configured for ADSS Server
* The ADSS Signing Service must be deployed and accessible (default port: 8777)
* See the [Ascertia ADSS Server documentation](https://www.ascertia.com) for installation and initial configuration
