Online UUIDs Generator

A UUID, which stands for Universally Unique Identifier, is a 128-bit number used to uniquely identify information in computer systems. UUIDs are commonly used in software development, databases, and other applications where unique identification is critical. By utilizing a UUID, you can prevent collisions or duplicates when creating new objects or records, ensuring that each identifier is unique across different systems and time periods. This enables better organization, data integrity, and overall system efficiency.

• - NIL UUID：NIL UUID는 모든 128비트가 제로로 설정된 특별한 UUID입니다. 이것은 00000000-0000-0000-0000-000000000000으로 표시되며, 일반적으로 "빈" 또는 "없는" UUID를 나타내는 데 사용됩니다.
• - UUID v1: 버전 1 UUID는 현재 타임스탬프와 UUID를 생성하는 기계의 MAC 주소의 조합을 사용하여 생성됩니다. 이것은 그것들을 유일하게 만들지만, 또한 그것들이 생성된 기계와 시간을 추적할 수 있게 합니다.
• - UUID v3: Version 3 UUID is generated using a namespace and name, both of which are hashed using the MD5 hashing algorithm. This ensures that the same namespace and name will always produce the same UUID, making them deterministic.
• - UUID v4: 버전 4의 UUID는 무작위 또는 의사 무작위 수로 생성됩니다. 이것은 그것들이 매우 높은 독특성을 가지고 있으며, 특정 기계나 시간으로 추적될 수 없음을 의미하지만, 그것들은 어떠한 고유한 의미나 구조도 가지고 있지 않습니다.
• - UUID v5: 버전 5의 UUID는 버전 3과 유사하지만 MD5 대신 SHA-1 해시 알고리즘을 사용합니다. 버전 3처럼, 그들은 결정적이며 같은 네임스페이스와 이름에 대해 항상 같은 UUID를 생성합니다.

각 버전은 고유성, 추적 가능성 및 결정성 측면에서 자체 사용 사례와 균형을 가지고 있습니다.

The UUID Generator is a straightforward and user-friendly web-based application that allows you to create random, secure, and unique UUIDs. This tool uses a combination of algorithms and random number generation techniques to generate a UUID, ensuring that the resulting UUID is highly unique and difficult to predict. To use the tool, simply select the version of the UUID and the quantity to generate at the top of the current page, then click the "Refresh" button. New UUIDs will be displayed for you to use in your project or application.

Yes, the tool uses a combination of algorithms and random number generation techniques to ensure that each UUID is highly unique and difficult to predict. While it is theoretically possible for UUID collisions to occur, the probability is extremely low, making it highly unlikely that two UUIDs generated by the tool will ever be the same. This high level of uniqueness and security makes the UUIDs generated by the tool suitable for use in various applications and projects.

Yes, feel free to use the UUIDs generated by the UUID Generator in all your projects, including commercial ones. This tool is designed to offer a convenient and reliable method for creating unique identifiers for various applications. Whether you are working on a personal project or developing a commercial application, the UUID Generator can help guarantee that your identifiers are both unique and secure.
