>>I can't see why anyone would want to use X9.42 DH these days. I have a hardware token that uses static-static DH with elliptic curves (I cannot change anything in this token and cannot force it to use Elgamal). The mode of operation of this token is very similar to X9.42 DH, so I wanted to implement all possible DH implementations, since they are very similar: in addition to a recipient's public key you also need your private key to encrypt a message; and you need to use common parameters. If you have a sample X9.42 DH certificate with a private key, please send them to me. If you don't have them, I will be able to make them. I know that since RSA patent have expired, X9.42 DH became "obsolete", but DH can use various "underlying layers" like elliptic curves, so it's tempting to support all breeds of DH once you support one. -- Best regards, Maxim Masiutin Ritlabs SRL http://www.ritlabs.com/ ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [email protected] Automated List Manager [email protected]
