The latest release of AmiSSL brings new enhancements for Amiga users and developers. With the AmiSSL 5.21 update, the open-source SSL/TLS library for AmigaOS now fully supports OpenSSL 3.5.1. This update introduces vital bug fixes and a refreshed certificate bundle, ensuring continued secure communication for Amiga software.
The AmiSSL 5.21 update integrates a fix for CVE-2025-4575, a low-severity OpenSSL bug affecting certificate trust flags. Developers will also benefit from the updated Mozilla-based CA bundle, dated May 20, 2025. Additionally, calls to the AmiSSL library interface are now better protected on AmigaOS 4.x systems, increasing robustness during runtime.
Designed to minimize overhead, AmiSSL allows multiple applications to share a single library, providing HTTPS and cryptographic functions without requiring custom implementations. Since version 5, AmiSSL includes a lightweight HTTP(S) client, simplifying online access for developers.
The history of AmiSSL stretches back to 1999, when Andrija Antonijevic released the first version. Co-developer Stefan Burström joined for v2, and the project evolved to support both 68k and PowerPC systems by 2006. After a pause in development, Jens Maus and Thore Böckelmann revived the project in 2012, updating its internals and porting it to modern OpenSSL versions.
The breakthrough came in 2016 when Oliver Roberts addressed long-standing base-relative addressing issues, clearing the path for AmiSSL v4. He has since led the project, introducing OpenSSL 3.x support with AmiSSL v5 in 2022 and continuing development up to today’s 5.21 release.
AmiSSL remains an essential dependency for IBrowse, the Amiga web browser. Earlier versions offered MiamiSSL as an option, but since IBrowse 2.5, AmiSSL has become mandatory—now requiring version 5. For those needing HTTPS on their Amiga system, AmiSSL is the go-to solution.
Downloads for both AmigaOS 3 and 4, along with the developer SDK, are available on the official AmiSSL site.
