The AmiSSL project is a collaborative effort to develop a port of OpenSSL in a shared library for Amiga-based systems (AmigaOS, MorphOS, AROS, etc). OpenSSL (www.openssl.org) is "an open source project that provides a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library."
The library together with its provided software development kit (SDK) tries to be 100% API/ABI compatible to the OpenSSL version it is based on. Due to it being a shared library, it can be used by several Amiga applications at the same time, without wasting resources.
AmiSSL v5 is a new major release which has been updated with full compatibility with OpenSSL 3.3. This includes important security related fixes, a built-in HTTP(S) client and comes with the latest encryption ciphers which are required nowadays to connect to modern SSL-based services such as HTTPS and SSH.
AmiSSL consists of four major components: the shared libraries, the public
root CA certificates, a port of the OpenSSL command-line tool and the
developer SDK.
The main library is amisslmaster.library which acts as a proxy and opens
the appropriate AmiSSL library (with compatibility to a certain OpenSSL
version) for the programs using AmiSSL. This mechanism allows different
AmiSSL versions to be installed in parallel, due to different applications
potentially requiring different versions. For this reason, it is important
that the latest version of amisslmaster.library is always installed.
The actual OpenSSL implementations are located in the shared libraries that
are usually stored inside the AmiSSL:Libs/AmiSSL directory. With the
exception of AmiSSL v1 libraries, none of them should be opened directly,
but instead via amisslmaster.library. The technical details on this can be
found in AmiSSL SDK documentation (see README-SDK).
The previous versions of libraries in AmiSSL directory should be kept when a new version of AmiSSL is released since they may still be used, as sometimes changes in the OpenSSL API/ABI or public structures mean that backwards compatibility cannot be maintained, usually for major OpenSSL updates only. When this is not an issue, the installer will delete any old versions that are no longer required and applications will benefit automatically from using the latest version without themselves needing to be recompiled/updated.
Each AmiSSL version is supplied with a full set of root CA certificates
which have been synchronized to the ones the Mozilla group usually distribute
with their products (e.g. Mozilla Firefox, etc.) and are stored in the
AmiSSL:Certs directory. When installing new updated AmiSSL versions, these
certificates are updated and expired ones are removed.
It is recommended that you do not manually add certificates to the
AmiSSL:Certs directory, but if you did, you should back them up and copy
them back after installing the latest AmiSSL. Normally, you should add and
maintain your own certificates in the AmiSSL:UserCerts directory, so that
no future AmiSSL release will delete them. Applications should store
certificates in AmiSSL:UserCerts and private keys in AmiSSL:Private.
A port of the OpenSSL tool is also included and usually installed to AmiSSL:
or C: during installation. It is a "command line tool for using the various
cryptography functions of OpenSSL's crypto library from the shell". The
documentation for the OpenSSL tool is included in the archive and can also
be reviewed online.
A sample openssl.cnf file is also installed to AmiSSL:, if it doesn't already
exist, along with the CA.pl helper script, both of which aid the certificate
generation features of the OpenSSL tool. The tsget.pl script is also included.
The AmiSSL SDK contains everything a developer needs to use OpenSSL in their applications, including C header files, Autodocs, autoopen link library, stub link library, examples and library interface description files. The first point of call being the README-SDK file which explains what needs to be done.
All applications compiled to use previous versions of AmiSSL v5 will automatically use the 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.
AmiSSL requires an Amiga-compatible operating system being installed (AmigaOS, MorphOS, AROS) with exec.library v38+ compatibility. Currently, AmiSSL is compatible with AmigaOS 4.0+/PPC, AmigaOS 3.0+/68020+ and MorphOS.
AmiUpdate may be used by AmigaOS 4.x users to automatically download and install any new AmiSSL version. Otherwise, the latest release archive can be downloaded from any of the following URLs:
https://github.com/jens-maus/amissl/releases
http://aminet.net/search?query=amissl-5
Once downloaded it should be unarchived to a temporary directory and the "Install" script used accordingly.
