AmiSSL

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 3.4.0 
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.

General 
------- 
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
software development kit (SDK)

Libraries 
--------- 
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.

Root CA Certificates 
-------------------- 
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".

The 'OpenSSL' command-line tool 
------------------------------- 
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: https://www.openssl.org/docs/man3.0/man1/openssl.html. 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.

Developer SDK 
------------- 
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.  

Backwards Compatibility 
----------------------- 
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.  

Requirements 
------------
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.

IMPORTANT NOTE 
-------------- 
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 in
time. If you are, however, interested in seeing AmiSSL v5 being ported for these
other Amiga-based platforms, please try to find motivated and talented
developers who could join our team as proper maintainers for these alternative
platforms. In addition, if you are a MorphOS or AROS developer yourself, feel
free to send proper pull requests to see your platform supported in one of the
next releases or please consider joining our team.
