Configuring a Client Public Key
This configuration task is only necessary for SSH users using publickey authentication.
For each SSH user that uses publickey authentication to login, you must configure the client’s DSA or
RSA host public key on the server, and configure the client to use the corresponding private key.
To configure the public key of an SSH client, you can:
z Configure it manually: You can input or copy the public key to the local host. The copied public key
must have not been converted and be in the distinguished encoding rules (DER) encoding format.
z Import it from the public key file: During the import process, the system will automatically convert
the public key to a string coded using the Public Key Cryptography Standards (PKCS). Before
importing the public key, you must upload the public key file (in binary) to the local host through
FTP or TFTP.
