RSA mixed up with DH/DSS

[sergio martinelli]

Hi,

A simple question, if we are using a RSA keypair to sign/encoding, and the other side are using DH/DSS also for sign/encoding we'll have some problem to decrypt?

We are doing it and we could decrypt as well but in the final line there are some garbage characters, something like binary characters or extended ascii...

Somebody knows why is there that trash?

thanks.

Not necessarily. As long as each side has access to the other's public key and the software you use can accept either type of keys, everything should work.

As for the so-called "garbage" characters at the end, that is often a symptom of incompatible padding schemes. Without more information or source code it is impossible to know.

That "garbage" was a mistake when was wrote the encrypted file.

..and the mixed up keypair work fine anyway.

thanks Greg!
