Displaying or exporting the local host public key
In some applications, such as SSH, to allow your local device to be authenticated by a peer device
through digital signature, you must display or export the local host public key, which will then be
specified on the peer device.
To display or export the local host public key, choose one of the following methods:
•
Displaying and recording the host public key information
•
Displaying the host public key in a specific format and saving it to a file
•
Exporting the host public key in a specific format to a file
If your local device functions to authenticate the peer device, you must specify the peer public key on the
local device. For more information, see "
Specifying the peer public key on the local device
."
Displaying and recording the host public key information
To display the local public key:
Task Command
Remarks
Display the local RSA public keys.
display public-key local
rsa
public
[
|
{
begin
|
exclude
|
include
}
regular-expression
]
Available in any view.
Use at least one command.
Display the local host public key.
display public-key local
dsa
public
[
|
{
begin
|
exclude
|
include
}
regular-expression
]
The
display public-key local
rsa
public
command displays both the RSA server and host public keys.
Recording the RSA host public key is enough.
After displaying the host public key, record the key information for manual configuration of the key on the
peer device.
Displaying the host public key in a specific format and saving it to a file
To display the local host public key in a specific format:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Display the local RSA or
DSA host public key in a
specific format.
•
To display the local RSA host public key:
{
In non-FIPS mode:
public-key local export rsa
{
openssh
|
ssh1
|
ssh2
}
{
In FIPS mode:
public-key local export rsa
{
openssh
|
ssh2
}
•
To display the local DSA host public key:
public-key local export dsa
{
openssh
|
ssh2
}
Use at least one command.
After you display the host public key in a specify format, save the key to a file (by using a method such
as copying and-pasting), and transfer this file to the peer device.
