Meziantou.FrameworkDeterministicGuid Class
Provides methods for generating deterministic (version 3 and version 5) GUIDs according to RFC 4122.
public static class DeterministicGuidExample
// Generate a GUID from a DNS name
var guid = DeterministicGuid.Create(DeterministicGuid.DnsNamespace, "example.com", DeterministicGuidVersion.Version5);
Assert.Equal(Guid.Parse("cfbff0d1-9375-5685-968c-48ce8b15ae17"), guid);
// The same input will always generate the same GUID
var guid2 = DeterministicGuid.Create(DeterministicGuid.DnsNamespace, "example.com", DeterministicGuidVersion.Version5);
Assert.Equal(guid, guid2);Properties
