Generate random API key online with Hash and Base64

API Keys are often used in digital projects, to secure the access to specific actions, fonctionnalitues, assets. 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.

Because 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.
We don't recommand symbols in this random API KEY generator, but you can force the use of symbols if you prefer.

We have created 6 types of preconfigured API Keys structure to help you generate strings that will be good for your project :

• Mixed letters & Numbers (Recommanded)
• Mixed letters, Numbers & Symbols
• Numbers
• Mixed letters
• Lowercase letters
• Uppercase letters

The lenght of the API key, and it's complexity, are important security factors. The longer and the more complex the API Key is, the harder it will be to break using brute force or dictionnaries.

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. One way to bring even more randomness and confidentiality in the process.

generate-random.org 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.

Our tool makes sure that every API Key in your list will be unique, and will only be added once. API Keys are strong identifiers for secured authentication in most APIs, using a combination of uniqueness and randomization. This tool will help you generate API Keys quickly, that you can click and paste wherever needed.

We also allow you download you results, for free, in several formats :

• Spreadsheet in Excel format .xlsx
• Spreadsheet in CSV format .csv
• JSON text file in .json
• Plain text file in .txt

Preconfigured API Keys generators :

• Alpha Numeric 64-bit API Key
• Alpha Numeric 128-bit API Key
• Alpha Numeric 256-bit API Key
• Alpha Numeric 512-bit API Key
• Alpha Numeric 1024-bit API Key
• Alpha Numeric 2048-bit API Key

We are based in France, and we specialize in randomizing stuff. We'll be happy to help.

generate-random.org uses no sort of Database, because it would take us in some complicated privacy issues that we are happy to stay away from, and also because it would be expensive to host for the environment and for our wallet.
You can be sure that what you was generated by our server is only between you and your browser.
