I ask here as those who read this list have an understanding of the word simple.
I am after some very simple public key encryption code which I intend to use to
encrypt the md5 of a license file on an embedded system - so in needs to be
really small and simple.
I am tempeted to use the plan9 RSA code, but is there somthing else even simpler
about? Perhaps less secure than RSA but stronger than a password embedded in
the code, XORed with 0xdeadbeef :-)
Anyone seen anything on the net?

TEA and XTEA are really, really simple and XTEA is resonably secure.
XXTEA & Block TEA have weaknesses, but XTEA should be simple enough &
fast enough for an embedded system.
Good Luck,

Thanks for the pointers guys but I believe TEA and blowfish are
not public key systems, perhaps my terminology is broken, I am after
a twin key system, seperate and different encryption and decryption
keys.
somthing like RSA or eliptic curves...

Ahh. No, neither TEA nor XTEA fit that category.
I'll take the rest to a private message...

Id be glad if you forwarded those messages to me : ) im also interested.
Not a real project just curiosity.
Thank you
