This fun API endpoint will tell you what version a specific UUID is. This can be useful for many purposes and also is more efficient for storing in indexed database columns. What is special about Timestamp-first UUIDs is that timestamp is at the beginning of the UUID so when stored in a database they will appear in the order they were created. These UUIDs have the current timestamp embedded in them to insure uniqueness. Generate a single v4 UUID string in the formatted 32 hexadecimal digits: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx Note that this module does not produce RFC 4122-compliant v4 (random) UUIDs (no encoding of variant and version information into the UUID). Timestamp-first (also, called "timestamp-first" or "ordered UUIDs") are similar to version-1 and version-4 UUIDs. The main differences is SHA-1 algorithm is used instead of MD5. Both versions are deterministic based on a namespace and name. Perl Module for Windows, Linux, Alpine Linux, MAC OS X, Solaris, FreeBSD, OpenBSD, Raspberry Pi and other single board computers. Version-5 UUIDs are similar to version-3. Version-1 is based, in part, on the time while version-4 is not. Version-4 UUIDs are similar to version-1. (Thank you to those who reported this issue on Github) This avoids some problems related to URL encoding certain characters. This module provides the creation of version 1 time based UUIDs. sfinks update-uuids will change the uuid for a given. UUID::Tiny is a lightweight, low dependency Pure Perl module for UUID creation and testing. You can also base64 encode your "name" parameter. jkeisers Mozilla tools include a UUID generator with output format of both C++ and IDL style. Namespace must be "ns:url", "ns:dns", "ns:OID", "ns:X500" or a properly formatted UUID. I need a Pure Perl, installation free UUID module. Create your free Platform account to download ActivePerl or customize Perl with the packages you require and get automatic updates. The main goal for UUID::Tiny was to create a UUID generator that can be used without installation and that has a simple, straightforward interface. This API does not allow you to generate multiple UUIDs at once because they would all be the same. b) UUID creation and comparison is the main focus. If you provide the same input you will get the same output every time. Version-3 UUIDs are deterministic and are based on an MD5 hash of the namespace place name you supply. Learn more about the different UUID versions. We do not provide a version-2 UUID generator. Version-1 UUIDs are based on time, the computer generating the UUID (in this case, it's our server), and pseudo-randomness. This is the same API that powers our UUID generator.Įndpoints that accept a count argument allow you to create up to 100 UUIDs at once.Īll endpoints are limited to 60 requests per minute per IP address. Daniel Mach <> - 1.6.2-26 - Mass rebuild - Daniel Mach <> - 1.6.2-25 - Mass rebuild - Michal Hlavinka <> - 1.6.2-24 - revert perl changes from last change - Michal Hlavinka <> - 1.6.We support generating all major UUID versions including version-1, version-3, version-4, version-5 and "timestamp-first" UUIDs. This API allows you to create UUIDs and GUIDs quickly on-the-fly for testing purposes.
