Can we have multiple public key for one private key in PKI.

I want to have one private key at server but multiple public keys for multiple clients. Can we generate multiple public keys for one private key?

You can have multiple "subkeys" that may be what you are looking for:

Depends on the algorithm you are using.

In general, this is very bad practice. Assuming you are using the same algorithm for each of the keys, providing multiple public keys to a single private key reduces the security logarithmically . You'd be smarter to have multiple public keys, each with it's own private key.

Can you specify the algorithm where i can have multiple public keys for a private key? As per my reading, I am unable to find this type of mechanism.
