#Perl uuid generator software#
UUID is one of the most used universal identifiers in software development.

* Unique IDentifiers (GUID), as well as several methods for producing them. A Tiny, URL-Friendly Unique String Generator for JavaScript. * RFC 4122 () defines a special type of Globally
* Generates a Universally Unique IDentifier, version 4. This was copied from the uniqid PHP function documentation. If you are using PHP, use the function below. If you have the Microsoft SDK installed on your system, you can use the utility uuidgen.exe, which is located in the "C:\Program Files\Microsoft SDK\Bin" directory. Set TypeLib = Nothing Create a UUID/GUID via the Windows Command Line WScript.Echo(left(NewGUID, len(NewGUID)-2)) Set TypeLib = CreateObject("Scriptlet.TypeLib")
#Perl uuid generator code#
Just save the code to a file called createguid.vbs, and then run cscript createguid.vbs at a command prompt. If you are on Windows, you can use the simple VBScript below to generate a UUID. Normal Hex Encoded Base64 Encoded VBScript Function to Generate a UUID/GUID It will return a different one each time. It is running on Linux.Ĭlick the button to run the GUID/UUID generator. The DATA::UUID Perl module by Alexander Golomshtok. UUID/GUID stand for Globally/Universally Unique Identifier. Use this utility to generate a UUID/GUID on the web. § Home > Index > General Interest Generate GUID Online
