{
dh-group-exchange-sha1
|
dh-group1-sha1
|
dh-group14-sha1
|

In FIPS mode:
ssh2 algorithm key-exchange
{
dh-group14-sha1
|
ecdh-sha2-nistp256
|
ecdh-sha2-nistp384
}

Default
SSH2 uses the key exchange algorithms
ecdh-sha2-nistp256
,
ecdh-sha2-nistp384
,
dh-group14-sha1
,
dh-group-exchange-sha1
, and
dh-group1-sha1
in descending order of priority
for algorithm negotiation.

Parameters
dh-group-exchange-sha1
:
Specifies the key exchange algorithm
diffie-hellman-group-exchange-sha1
.
dh-group1-sha1
: Specifies the key exchange algorithm
diffie-hellman-group1-sha1
.
dh-group14-sha1
: Specifies the key exchange algorithm
diffie-hellman-group14-sha1
.
ecdh-sha2-nistp256
: Specifies the key exchange algorithm
ecdh-sha2-nistp256
.
ecdh-sha2-nistp384

Usage guidelines
If you specify the key exchange algorithms, SSH2 uses only the specified algorithms for algorithm
negotiation. The algorithm specified earlier has a higher priority during negotiation.
Examples
# Specify the algorithm
dh-group1-sha1
as the key exchange algorithm for SSH2.
