I actually wrote most of the 65816-crypto package years ago, partially 
with TLS in mind, but actually implementing TLS on the IIGS would still 
be quite a bit of work and might be prohibitive in terms of performance.

The biggest issue with TLS would be establishing the connection and 
negotiating the encryption keys. That phase of TLS normally requires 
public-key cryptography algorithms, which are not currently included in 
the 65816-crypto package and which can be quite slow.

If you could get past that phase to the point of sending encrypted data 
back and forth, then algorithms in the 65816-crypto package (e.g. AES 
and HMAC-SHA256) could be used. That would still be pretty slow, but 
maybe usable for some things, especially on an accelerated IIGS.
