Version 5 - Version 5 UUIDs are similar to version 3 with stronger encryption. However, the possibility of duplication for version 4 UUIDs is extremely low practically. There is no guarantee that version 4 UUIDs will be unique when generated. Version 4 - Version 4 UUIDs are completely randomized. Version 3 - Version 3 makes use of the MD5 hashing algorithm to generate a UUID. Therefore, most UUID libraries skip implementing version 2 which result in version 2 UUIDs not being used practically. This version is reserved by RFC 4122, and no further details are announced. Version 2 - Version 2 UUIDs are similar to version 1 with DCE security. Version 1 UUIDs are mostly used in transactions to ensure uniqueness.

However, the pro is version 1 UUIDs generated on the same machine will always be unique according to the different timestamps. The main con of version 1 UUIDs is that the MAC address of the machine used to generate them is exposed which could lead to security issues. Version 1 - Version 1 UUIDs are generated from the combination of the MAC address of a machine and the current timestamp in nanoseconds. To generate a new UUID, repeat the above steps again to generate a UUID.1e1cf92c-5f52-4307-ae7d-178f65bebfb8 UUID versions explained

Paste it where you need it to use the UUID.

Here is how to use the UUID Generate in a few simple steps: Under the hood, Create UUID uses uuid package to generate RFC-compliant UUIDs. If you need to generate a UUID Version 4, you can use our UUID Generator.

Quickly spot matches when reviewing longer lists of information matched with UUIDs.

Generate simpler UUIDs that don't give away information about the source (like Version 1 UUIDs do when they take the MAC address).

This is because you would need to generate trillions of Version 4 UUIDs before you get the same random set of bits. Since Version 4 UUIDs use a random set of generated numbers, duplication is possible, but highly unlikely. It is generated using random numbers and no logic, which is why Version 4 UUIDs are not typically used if you need to generate a unique ID that is time-sensitive.

Version 4 UUIDs are common unique identifier used by software developers, usually when debugging. Version 4 is often considered the most common ways to generate a UUID. Version 5 UUID: Which uses an SHA-1(Secure Hash Algorithm 1) hash of a namespace and name to generate a UUID.Version 4 UUID: Which uses random numbers to generate a unique UUID.

Version 3 UUID: Which uses an MD5 (Message Digest Algorithm 5) hash of namespace and name to generate a UUID.

Version 1 UUID: Which uses a timestamp and the MAC address of the computer it was created from to generate a UUID.

There are four different types of UUID's, including: It is a 128-bit value used in software development to identify unique values. UUID stands for Universally Unique Identifier. The reason UUID's are considered to be unique indefinitely is because they either use timestamps or a random string of numbers that will never be reproduced in exactly the same way ever again. This string of bits is most commonly used in software development and is designed to be unique both now and in the future. It is a binary digit (also known as a bit) that has a 128-bit value. A UUID (Universally Unique Identifier) is a value used to identify uniqueness.
