I actually wrote most of the 65816-crypto package years ago, partially
with TLS in mind

Following up publicly after private email seems to have not gotten through (spam perhaps)

I see you have your own crypto routine library.
Were you aware of the hashtool and crypto toolsets? I’d be interested in hearing your thoughts about this model of providing routines for
application reuse. And perhaps you may consider contributing your code to
them or taking them over?
QKumba has implemented cha-cha which I requested and should include at some point.

I think all the available ciphers for IIgs are now deprecated which makes establishing a connection more challenging when the goal posts keep
changing. Perhaps we can offload the encryption / decryption to some other mechanism (perhaps UltimateDrive could be used).

Hi Stephen,

Perhaps we can offload the encryption / decryption to some other
mechanism (perhaps UltimateDrive could be used).

[...] some sort of offload mechanism
might well be more practical than doing everything on the GS.

I don't know what the UltimateDrive brings to the table that you desire,
but...

1.

The A2Pico:
* is software-defined hardware
* is open source - both hardware and firmware
* is very DIY friendly due to its through-hole variant without any chips to
be programmed
* is available as completely assembled SMD variant for a pretty affordable price
* comes with a reusable library that contains the code necessary to
communicate with the A2
* can easily be programmed in C

2.

If you define a "crypto accelerator" software interface based on a
SmartPort character device, then this interface can be implemented both
* internally (i.e. based on A2Pico)
* externally (i.e. based on FujiNet)
in a similar way a "usual" SmartPort block device can be implemented both internally (i.e. CFFA3000) and externally (i.e. Floppy Emu).
