tango.util.uuid.NamespaceGenV5
Generate a UUID according to version 5 of RFC 4122.
These UUIDs are generated in a consistent, repeatable fashion. If you
generate a version 5 UUID once, it will be the same as the next time you
generate it.
To create a version 5 UUID, you need a namespace UUID, generated in some
reasonable fashion. This is hashed with a name that you provide to generate
the UUID. So while you can easily map names to UUIDs, the reverse mapping
will require a lookup of some sort.
This module publicly imports Uuid, so you don't have to import both if you
are generating version 5 UUIDs. Also, this module is just provided for
convenience -- you can use the method Uuid.byName if you already have an
appropriate digest.
Version 5 UUIDs use SHA-1 as the hash function. You may prefer to use
version 3 UUIDs instead, which use MD5, if you require compatibility with
another application.
To use this module:
import tango.util.uuid.NamespaceGenV5;
auto dnsNamespace = Uuid.parse("6ba7b810-9dad-11d1-80b4-00c04fd430c8");
auto uuid = newUuid(namespace, "rainbow.flotilla.example.org");
- Uuid newUuid(Uuid namespace, char[] name);
- Generates a UUID as described above.
