WebCurrently, SSH performs the initial key exchange using the "diffie-hellman-group1-sha1" method [RFC4253]. This method prescribes a fixed group on which all operations are performed. The Diffie-Hellman key exchange provides a shared secret that cannot be determined by either party alone. WebDiffie-Hellman key exchange algorithm uses fixed primes as a base for computing the secret key used to secure the communication channel. The size of the small prime pdeployed dictates the security level of the generated key. This in turn defines the effective security provided by the Diffie-Helman key exchange algorithm.
