Hi,
I'm looking for a secure implementation of Shamir Secret Sharing
algorithm in OpenSSL Project. I coudn't find anything in the page
(www.openssl.org).
Is there any free implementation like that of Shamir's algorithm?
We did talk about it a few years ago. However, when I thought about
it, I was disturbed by the fact that you have to put together the
secret, THEN decipher whatever you need to decipher. In a distributed
or otherwise potentially hostile environment, it means that someone
will get the secret, and then, the sharing scheme is moot.
There was some further talk about a scheme where the message could be
partially deciphered with each secret share. I don't remember all the
details, and the documents I had disappeared in a disk crash (yeah,
I'm much better at keeping backups these days :-)).
Anyway, that's how far we got...
Cheers,
Richard

I was looking this discussion you have mentioned. But for my
application I just need a free secure implementation of Shamir's Secret
Sharing algorithm. Then I'd like to know if any implementaion like that
(free) exists in OpenSSL project or in another one.
Thanks in advance,
Rafael Cividanes.
