This is version 5.8 of the open-source based AmiSSL library for Amiga based operating systems. AmiSSL v5 is a new major release which has been updated with full compatibility with OpenSSL 3.1. This includes important security related fixes, a built-in HTTP(S) client and comes with new encryption ciphers which are required nowadays to connect to modern SSL-based services such as HTTPS and SSH.


  • Switched to OpenSSL 3.1, with full compatibility with the latest OpenSSL 3.1.0 (14.3.2023) version, which includes:
    • SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
    • Performance enhancements and new platform support including new assembler code algorithm implementations.
    • Deprecated LHASH statistics functions.
    • FIPS 140-3 compliance changes.
  • Replaced many common Exec semaphore protected OpenSSL operations with atomic inline assembly code on both OS3 and OS4, decreasing overhead and increasing performance.
  • Fixed bug in the 5.7 SDK (applications built with it should be recompiled using the 5.8 SDK).

For details on all changes, see the full commit log.

Backwards Compatibility

All applications compiled to use previous versions of AmiSSL v5 will automatically use this latest version once installed. Old applications will continue to use AmiSSL v4 or older and will need to be recompiled with the updated SDK in order to start using AmiSSL v5. Besides this difference, AmiSSL v5 can be installed on top of any previous AmiSSL versions, which ensures that applications compiled for AmiSSL v1/v2/v3/v4 continue to work.


AmigaOS 4.0+/PPC, AmigaOS 3.0+/68020+ or MorphOS


This release comes with binaries for the AmigaOS4/PPC and AmigaOS3/m68k platform only. Unfortunately, due to lack of motivated developers we couldn't provide native binaries for the MorphOS/PPC or AROS (PPC, i386, x86_64) platform. If you are, however, interested in seeing AmiSSL v5 being ported to these other Amiga-based platforms, please try to find motivated and talented developers who join our team as maintainers for these alternative platforms. In addition, if you are a MorphOS or AROS developer yourself, feel free to send pull requests to see your platform supported in one of the next releases.
