Good work, those involved. I'm looking forward to trying this after the other Amiga/MOS ports didn't work too well.
@All
These are straight linux ports it seems, so it won't work with miami in that sense: it's a suite of cmd line tools and libs (not Amiga libs). If you expect to simply plug it in to your Amiga and go, get AmiSSL instead. These are power tools most people will never need (although ssh and sftp are useful to average users as well).
But as for security: you don't get much securer than SSL, open source or not. It's virtually uncrackable. I say virtually, because if you had all the supercomputers in the world and some years, maybe you could crack it then. ;-)
I'd also remind Americans and French that you're not allowed to download encryption technologies. Your free countries don't allow digital privacy. :-P
