Manually specifying the peer public key on the local device

As shown in Figure 68, 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.

• Manually specify the host public key of Device A's public key pair on Device B.

# Create local RSA key pairs on Device A, setting the modulus length to the default, 1024 bits.

[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]:

The output shows that the host public key of Device A saved on Device B is consistent with the one created on Device A.
