Has anybody ever set up a Digital Signature to be used in legal binding contracts. What I have read is you need private and public keys need to be created to ensure the authication of the person signing. What are these? Where do you get these? I am using PHP, can I create them with PHP? Any information would be helpful.
Thanks In Advance
Mike

You will need OpenSSL or equiv. You can generate the private/public keys using openssl.
You would most likely want to distribute the private key using snail mail or other physical transport and keep the public key on the server for decrypting the signed document.
Ultimately, you would want to get a key from a CA such as Verisign.
PECL has some interesting functions in the "crypt" repository as well.
