Class ZCertStore

java.lang.Object

org.zeromq.ZCertStore

public class ZCertStore
extends Object

To authenticate new clients using the ZeroMQ CURVE security mechanism, we have to check that the client's public key matches a key we know and accept. There are numerous ways to store accepted client public keys. The mechanism CZMQ implements is "certificates" (plain text files) held in a "certificate store" (a disk directory). This class works with such certificate stores, and lets you easily load them from disk, and check if a given client public key is known or not. The ZCert class does the work of managing a single certificate.

Those files need to be in ZMP-Format which is created by ZConfig
