v3

v3(name, namespace): string

Defined in: src/uuid/v3.ts:21

Version 3 — name-based, using MD5 (RFC 9562 §5.3).

The same namespace and name always give the same UUID, on any machine and in any language. MD5 is broken for signatures, which is why §5.3 says new designs should prefer v5; v3 remains for interoperating with what already exists.

Parameters

name

string | Uint8Array<ArrayBufferLike>

namespace

string | Uint8Array<ArrayBufferLike>

Returns

string

Example

v3("www.example.com", NAMESPACE.DNS);
// "5df41881-3aed-3515-88a7-2f4a814cf09e"  the RFC's own vector

// Any of the four namespaces of Appendix A, or a UUID of your own.
v3("/orders/42", NAMESPACE.URL);
