The output shows that the host public key of Device A saved on Device B is consistent with the one
created on Device A.
Importing a peer public key from a public key file
Network requirements
As shown in Figure 79, to prevent illegal access, Device B (the local device) authenticates Device A (the
peer device) through a digital signature. Before configuring authentication parameters on Device B,
configure the public key of Device A on Device B.
• Configure Device B to use the asymmetric key algorithm of RSA.
• Import the host public key of Device A from the public key file to Device B.
Figure 79 Network diagram
Configuration procedure
1. Create key pairs on Device A and export the host public key:
# Create local RSA key pairs on Device A, setting the modulus length to the default, 1024 bits.
<DeviceA> system-view
[DeviceA] public-key local create rsa
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Press CTRL+C to abort.
Input the bits of the modulus[default = 1024]:
