Export Restrictions
We cannot distribute the SSL files directly due the complexity of possible export restrictions, however you are free to download and use them. The restrictions only apply to export, not import. In recent years the restrictions have been lifted significantly, however it is still a possible legal liability and thus we choose not to take the risk by hosting them on our server.
Indy Stand Alone Servers Only
The SSL libraries are only needed by stand alone servers using Indy. Applications deployed as Http.sys or ISAPI use SSL from the web server host. SSL is not available in IntraWeb evaluation editions.
Indy Open SSL
The current version of Indy used in IntraWeb supports two different versions of OpenSSL: 1.0.x and 1.1.x. We strongly recommend using OpenSSL 1.1.x, as it fixes many vulnerabilities that were discovered over the years in the OpenSSL 1.0 series.
However, older IntraWeb versions (12, 14, and 15 prior to 15.4.0) can only use OpenSSL 1.0.x.
The table below lists the recommended versions and download links.
| IntraWeb 12, 14, 15 (before 15.4.0) | IntraWeb 15.4.0+ and 16 | |
|---|---|---|
| Supported OpenSSL versions | 1.0.x | 1.0.x and 1.1.x |
| Recommended OpenSSL version | 1.0.2u | 1.1.1w |

| Direct download | x86 x64 |

Certificate Tools
Every IntraWeb installation – even the evaluation version – includes a full-featured Certificate Manager that can be used to generate self-signed certificates for development, request Let’s Encrypt certificates for production, convert certificate formats, install certificates on Windows, and much more.
The IntraWeb Certificate Manager is useful for all types of IntraWeb applications, from Indy standalone servers to Http.sys and ISAPI.
