WebMost signature algorithms include hashing and additional padding (e.g., "ssh-dss" specifies SHA-1 hashing). In that case, the data is first hashed with HASH to compute H, and H is then hashed with SHA-1 as part of the signing operation. It then goes to define diffie-hellman-group1-sha1, just to show that SHA-1 is indeed the hash mentioned above: WebAug 11, 2014 · Diffie-Hellman (DH) allows two devices to establish a shared secret over an unsecure network. ...
