NAME
amigaget
Get https files from the internet on your Amiga - all CPUs.
This program only needs a bsdsocket.library to work. It's 'small' and fast.
No other nonstandard dependencies!
The 68000 version is slower, caused by using 16x16->32 multiplication.
Expected speed, tested with a 1217kB reference file on github.com
WinUAE 68000 original speed 4kB/s
WinUAE 68020 original speed 49kB/s
It comes with no known certificates but you can install certificates if
asked for. These end up in sys:Prefs/Env-Archive/certs.
It supports 0=SSL3.0, 1=TLS1.0, 2=TLS1.1, 3=TLS1.2 and 4=TLS1.3.
Written in C++ using a STL variant, and still lean!
Speed criticial functions are now written in assembly.
Based on my Java SSL/TLS implementation that grew over the years,
starting when Java 1.1 was available and the export restrictions forbid
strong cryptopgraphy.
