Class RandomUidGenerator

  • All Implemented Interfaces:
    UidGenerator
    public class RandomUidGenerator
extends Object
implements UidGenerator
    Extract from RFC7986: 
     The description of the "UID" property in [RFC5545] contains some
 recommendations on how the value can be constructed.  In particular,
 it suggests use of host names, IP addresses, and domain names to
 construct the value.  However, this is no longer considered good
 practice, particularly from a security and privacy standpoint, since
 use of such values can leak key information about a calendar user or
 their client and network environment.  This specification updates
 [RFC5545] by stating that "UID" values MUST NOT include any data that
 might identify a user, host, domain, or any other security- or
 privacy-sensitive information.  It is RECOMMENDED that calendar user
 agents now generate "UID" values that are hex-encoded random
 Universally Unique Identifier (UUID) values as defined in
 Sections 4.4 and 4.5 of [RFC4122].

 The following is an example of such a property value:
