Parameters
keyid : Specifies an authentication key ID in the range of 1 to 4294967295.
cipher : Sets a ciphertext key.
simple : Sets a plaintext key. This key will be saved in cipher text for security purposes.
value : Specifies the MD5 authentication key string. This argument is case sensitive. If simple is specified,
it is a string of 1 to 32 characters. If cipher is specified, it is a string of 1 to 73 characters. If neither cipher
nor simple is specified, you set a plaintext key string.
Usage guidelines
In a security-demanding network, the NTP authentication feature should be enabled for a system running
NTP. This feature enhances the network security by means of the client-server key authentication, which
prohibits a client from synchronizing with a device that has failed authentication.
