![]() The first 6 octets are the number of 4 usec units of time that have passed since 1/1/80 0000 GMT. Initially, Apollo Computer designed the UUID with the following wire format: The legacy wire format Binary wire format Ī UUID is a 128-bit label. The "Revise Universally Unique Identifier Definitions Working Group" is working on an update which will introduce additional versions. The Internet Engineering Task Force (IETF) published the Standards-Track RFC 4122, technically equivalent to ITU-T Rec. UUIDs are documented as part of ISO/ IEC 11578:1996 " Information technology – Open Systems Interconnection – Remote Procedure Call (RPC)" and more recently in ITU-T Rec. UUIDs are standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). When in July 20 was published as a proposed IETF standard, the ITU had also standardized UUIDs, based on the previous standards and early versions of RFC 4122. RFC 4122 registered a URN namespace for UUIDs and recapitulated the earlier specifications, with the same technical content. Later, the Microsoft Windows platforms adopted the DCE design as "Globally Unique IDentifiers" (GUIDs). The design of the DCE UUIDs was partly based on the NCS UUIDs, whose design was in turn inspired by the ( 64-bit) unique identifiers defined and used pervasively in Domain/OS, an operating system designed by Apollo Computer. Later, the Open Software Foundation's (OSF) used UUIDs for their Distributed Computing Environment (DCE). ![]() In the 1980s Apollo Computer originally used UUIDs in the Network Computing System (NCS). ![]() Information labeled with UUIDs by independent parties can therefore be later combined into a single database or transmitted on the same channel, with a negligible probability of duplication.Īdoption of UUIDs is widespread, with many computing platforms providing support for generating them and for parsing their textual representation. Thus, anyone can create a UUID and use it to identify something with near certainty that the identifier does not duplicate one that has already been, or will be, created to identify something else. While the probability that a UUID will be duplicated is not zero, it is generally considered close enough to zero to be negligible. Their uniqueness does not depend on a central registration authority or coordination between the parties generating them, unlike most other numbering schemes. When generated according to the standard methods, UUIDs are, for practical purposes, unique. The term Globally Unique IDentifier ( GUID) is also used, mostly in Microsoft systems. You can be sure that what you was generated by our server is only between you and your browser.A Universally Unique IDentifier ( UUID) is a 128-bit label used for information in computer systems. That we are happy to stay away from, and also because it would be expensive to host for the environment and for our wallet. uses no sort of Database, because it would take us in some complicated privacy issues If you expect more from this tool, contact me : are based in France, and we specialize in randomizing stuff. We also allow you download you results, for free, in several formats : This tool will help you generate API Keys quickly, that you can click and paste wherever needed. Our tool makes sure that every API Key in your list will be unique, and will only be added once.ĪPI Keys are strong identifiers for secured authentication in most APIs, using a combination of uniqueness and randomization. allows you to generate up to 500 random API Keys from 128 to 256 bits length, and types alpha-numeric, numeric of alphabetic, with their md5 hash and base64 representation. One way to bring even more randomness and confidentiality in the process. To make our service complete, we provide you with encoding and hashing to use your api Keys in more subtle ways : Base64, MD5 hash, SHA256 hash ans SHA512 hash. The longer and the more complex the API Key is, the harder it will be to break using brute force or dictionnaries. The lenght of the API key, and it's complexity, are important security factors. We have created 6 types of preconfigured API Keys structure to help you generate strings that will be good for your project : We don't recommand symbols in this random API KEY generator, but you can force the use of symbols if you prefer. ![]() Generating API keys can be easilly done with scripts and programms, but they often rely on libraries and code writting that will make this task longer, than simply generating the API Key online.īecause api keys need to be eays to copy / paste, and because the can be stored in config files of databases, one convention is to avoid symbols and stick to simple english alphabet letters and arabic (conventional) numbers. Generate random API key online with Hash and Base64ĪPI Keys are often used in digital projects, to secure the access to specific actions, fonctionnalitues, assets.
