When invoking configure, specify -with-uuid=bsd to use the BSD functions, or -with-uuid=e2fs to use e2fsprogs' libuuid, or -with-uuid=ossp to use the OSSP UUID library. On Linux, macOS, and some other platforms, suitable functions are provided in the libuuid library, which originally came from the e2fsprogs project (though on modern Linux it is considered part of util-linux-ng). On FreeBSD and some other BSD-derived platforms, suitable UUID creation functions are included in the core libc library. uuid-ossp can now be built without the OSSP library on some platforms. Let’s begin with understanding the syntax used for writing a UUID generate function. While the OSSP UUID library can still be found at, it is not well maintained, and is becoming increasingly difficult to port to newer platforms. Contact us with suggestions or corrections. We do our best to make the tools and API intuitive and easy-to-use.

Historically this module depended on the OSSP UUID library, which accounts for the module's name. Thanks for using This site provides a free tool and API for generating UUIDs on-the-fly. Version 5 should be preferred over version 3 because SHA-1 is thought to be more secure than MD5. Generates a version 5 UUID, which works like a version 3 UUID except that SHA-1 is used as a hashing method. This function returns a version 4 (random) UUID. Uuid_generate_v5 ( namespace uuid, name text ) → uuid PostgreSQL includes one function to generate a UUID: genrandomuuid () uuid. Generates a version 4 UUID, which is derived entirely from random numbers.

The generation of UUIDs by this method has no random or environment-dependent element and is therefore reproducible. The name parameter will be MD5-hashed, so the cleartext cannot be derived from the generated UUID. SELECT uuid_generate_v3(uuid_ns_url(), '') (It could be any UUID in theory.) The name is an identifier in the selected namespace. The namespace should be one of the special constants produced by the uuid_ns_*() functions shown in Table F.35. Generates a version 3 UUID in the given namespace using the specified input name.

Uuid_generate_v3 ( namespace uuid, name text ) → uuid I know that I can use SELECT NEWID () to generate a UUID, but I have to go to the query result, copy the generated UUID to my clipboard (killing whatever was in there before) and then go back to the code and replace the query which is an awful way of dealing with this. Generates a version 1 UUID, but uses a random multicast MAC address instead of the real MAC address of the computer. Note that UUIDs of this kind reveal the identity of the computer that created the identifier and the time at which it did so, which might make it unsuitable for certain security-sensitive applications. This involves the MAC address of the computer and a time stamp.
