Technical Explanation:

Generator Conformance to UUID Specifications:

This GUID / UUID Generator is engineered to produce identifiers that strictly adhere to the UUID (Universally Unique Identifier) specifications outlined in RFC 4122. These generated identifiers are 128-bit values, typically represented as 32 hexadecimal characters, often separated by hyphens in a "8-4-4-12" format.

UUID Version 4 and GUIDs:

This generator primarily generates identifiers that align with the UUID version 4 specification. However, it's important to note that these generated values are technically referred to as GUIDs (Globally Unique Identifiers) according to Microsoft's terminology.


While both GUIDs and UUIDs serve the same purpose of providing unique identifiers, they are named differently based on their specific origins. GUIDs are commonly associated with Microsoft technologies, whereas UUIDs are a more general term used across various platforms.


User Responsibility for Data Integrity:

While this GUID / UUID Generator is designed to generate identifiers in accordance with UUID specifications, it's imperative for users to exercise due diligence in ensuring the generated data is correct and unique for their specific use case.

No Guarantee of Absolute Uniqueness:

We want to emphasize that while the generator aims to provide unique identifiers, we cannot guarantee absolute uniqueness. It's possible, albeit highly unlikely, that a collision may occur in rare circumstances. Therefore, it remains the user's responsibility to verify the uniqueness of generated identifiers, especially in critical or security-sensitive applications. By using this generator, you acknowledge and accept the responsibility for validating and verifying the uniqueness and correctness of the generated data for your specific purposes.
