Generate Api Key In C
- For example, if an attacker creates several API keys for himself, it may be possible to determine a future random number used to generate another user's API key. In general, do not consider UUIDs to be securely unguessable.
- Create a user in IAM for the person or system who will be calling the API, and put that user in at least one IAM group with any desired permissions. See Adding Users. You can skip this if the user exists already. Get these items: RSA key pair in PEM format (minimum 2048 bits). See How to Generate an API Signing Key. Fingerprint of the public key.

We all know how valuable APIs are. They’re the gateway to exploring other services, integrating with them, and building great solutions faster.
You might have built or are thinking of building APIs for other developers to use. An API needs some form of authentication to provide authorised access to the data it returns.
There are several authentication standards available today such as API Keys, OAuth, JWT, etc.
In this article, we’ll look at how to correctly manage API Keys to access APIs.
So Why API Keys?
API Keys are simple to use, they’re short, static, and don’t expire unless revoked. They provide an easy way for multiple services to communicate.
If you provide an API for your clients to consume, it’s essential for you to build it in the right way.
Let’s get started, and I’ll show you how to build API Keys the right way.
API Key Generation
Since the API key itself is an identity by which to identify the application or the user, it needs to be unique, random and non-guessable. API keys that are generated must also use Alphanumeric and special characters. An example of such an API key is zaCELgL.0imfnc8mVLWwsAawjYr4Rx-Af50DDqtlx.
Secure API Key Storage
Since the API key provides direct access to data, it’s pretty much like a password that a user of a web or mobile app provides to gain access to the same data.
Think about it. The reason we need to store API keys is to make sure that the API key in the request is valid and issued by us (just like a password).
We don’t need to know the raw API key, but just need to validate that the key is correct. So instead of storing the key in plain text (bad) or encrypting it, we should store it as a hashed value within our database.
A hashed value means that even if someone gains unauthorised access to our database, no API keys are leaked and it’s all safe. The end user would send the raw API key in each API request, and we can validate it by hashing the API key in the request and compare the hashed key with the hash stored within our database. Here is a rough implementation of it in Java:
Generate Api Key In C Pdf
In the code above, the primary key will be a combination of the prefix and the hash of the API key {prefix}.{hash_of_whole_api_key}.
But hold on, there is more. Storing a hashed value brings specific usability problems. Let’s address those now.
Presenting the API Key to users
Since we don’t store the original API key, we can show it only once to the user, at the time of creation. So be sure to alert users that it cannot be retrieved again, and they need to generate a new token if they forget to copy the API key and store it safely. You can do something like this:
How users can identify a generated API Key later
Another problem is how users identify the right API key in your console if they need to edit or revoke it. This can be solved by adding a prefix to the API key. Notice in the picture above the first 7 characters (that’s our prefix), separated by the dot.
Now you can store this prefix in the database and display it in the console so users are able to quickly identify the right API key entry, like this:
Don’t give the API Key all the power
Api Key Codeigniter
One common mistake that API key providers make is providing one key to access everything, since it’s easy to manage. Don’t do that. Assume that a user just needs to read an email, and generates an API key. But that key now has full access to other services, including deleting records in the database.
The right approach is to allow the end users to properly restrict API Key access and choose specific actions that an API key can carry out. This can be done by providing scopes, where each scope represents a specific permission.
For example,
- if you need an API key to just send emails, you can generate an API key with the scope as “email.send”
- if the end user has multiple servers and each carries out a specific action, then a separate API key can be generated with a specific scope.
So while creating the API key, allow users to select what access that API key should have, as in the image below.
This way users can generate multiple API keys, each with specific rules of access for better security. And when an API request is received, you can check if the API Key has the right scope to access that API. Now the database looks something like this:
Rate limiting API keys
Yes, you might already know it, but it is important to rate limit requests made with specific API Keys to ensure no bad actor can take down your API servers or cause performance issues that affect your other customers. Having a proper rate limiting and monitoring solution keeps the API service healthy.
Conclusion
API keys, when built right, are still a great way to communicate with another server. As we reviewed in this article, following certain practices offers benefits to both API consumers and API providers. Hope this helps you.
Happy Securing your APIs!
Generate Api Key
-->All requests to a search service need a read-only api-key that was generated specifically for your service. The api-key is the sole mechanism for authenticating access to your search service endpoint and must be included on every request. In REST solutions, the api-key is typically specified in a request header. In .NET solutions, a key is often specified as a configuration setting and then passed as Credentials (admin key) or SearchCredentials (query key) on SearchServiceClient.
Keys are created with your search service during service provisioning. You can view and obtain key values in the Azure portal.

What is an api-key
An api-key is a string composed of randomly generated numbers and letters. Through role-based permissions, you can delete or read the keys, but you can't replace a key with a user-defined password or use Active Directory as the primary authentication methodology for accessing search operations.
Two types of keys are used to access your search service: admin (read-write) and query (read-only).
| Key | Description | Limits |
|---|---|---|
| Admin | Grants full rights to all operations, including the ability to manage the service, create and delete indexes, indexers, and data sources. Two admin keys, referred to as primary and secondary keys in the portal, are generated when the service is created and can be individually regenerated on demand. Having two keys allows you to roll over one key while using the second key for continued access to the service. Admin keys are only specified in HTTP request headers. You cannot place an admin api-key in a URL. | Maximum of 2 per service |
| Query | Grants read-only access to indexes and documents, and are typically distributed to client applications that issue search requests. Query keys are created on demand. You can create them manually in the portal or programmatically via the Management REST API. Query keys can be specified in an HTTP request header for search, suggestion, or lookup operation. Alternatively, you can pass a query key as a parameter on a URL. Depending on how your client application formulates the request, it might be easier to pass the key as a query parameter: GET /indexes/hotels/docs?search=*&$orderby=lastRenovationDate desc&api-version=2019-05-06&api-key=[query key] | 50 per service |
Visually, there is no distinction between an admin key or query key. Both keys are strings composed of 32 randomly generated alpha-numeric characters. If you lose track of what type of key is specified in your application, you can check the key values in the portal or use the REST API to return the value and key type.
Note
It is considered a poor security practice to pass sensitive data such as an api-key in the request URI. For this reason, Azure Cognitive Search only accepts a query key as an api-key in the query string, and you should avoid doing so unless the contents of your index should be publicly available. As a general rule, we recommend passing your api-key as a request header.
Find existing keys
You can obtain access keys in the portal or through the Management REST API. For more information, see Manage admin and query api-keys.

Create query keys
Query keys are used for read-only access to documents within an index for operations targeting a documents collection. Search, filter, and suggestion queries are all operations that take a query key. Any read-only operation that returns system data or object definitions, such as an index definition or indexer status, requires an admin key.
Restricting access and operations in client apps is essential to safeguarding the search assets on your service. Always use a query key rather than an admin key for any query originating from a client app.
Sign in to the Azure portal.
List the search services for your subscription.
Select the service and on the Overview page, click Settings >Keys.
Click Manage query keys.
Use the query key already generated for your service, or create up to 50 new query keys. The default query key is not named, but additional query keys can be named for manageability.
Note
A code example showing query key usage can be found in Query an Azure Cognitive Search index in C#.
Regenerate admin keys
Two admin keys are created for each service so that you can rotate a primary key, using the secondary key for business continuity.
- In the Settings >Keys page, copy the secondary key.
- For all applications, update the api-key settings to use the secondary key.
- Regenerate the primary key.
- Update all applications to use the new primary key.
If you inadvertently regenerate both keys at the same time, all client requests using those keys will fail with HTTP 403 Forbidden. However, content is not deleted and you are not locked out permanently.
You can still access the service through the portal or the management layer (REST API, PowerShell, or Azure Resource Manager). Management functions are operative through a subscription ID not a service api-key, and thus still available even if your api-keys are not.
After you create new keys via portal or management layer, access is restored to your content (indexes, indexers, data sources, synonym maps) once you have the new keys and provide those keys on requests.
Secure api-keys
Reaper of souls cd key generator. Key security is ensured by restricting access via the portal or Resource Manager interfaces (PowerShell or command-line interface). As noted, subscription administrators can view and regenerate all api-keys. As a precaution, review role assignments to understand who has access to the admin keys.
- In the service dashboard, click Access control (IAM) and then the Role assignments tab to view role assignments for your service.
Members of the following roles can view and regenerate keys: Owner, Contributor, Search Service Contributors
Note
For identity-based access over search results, you can create security filters to trim results by identity, removing documents for which the requestor should not have access. For more information, see Security filters and Secure with Active Directory.
