Serial Key Generator is application specially designed for software developers to help protect your applications by serial key registration. Just in a few clicks you are able to generate serial. Generating Keys for Encryption and Decryption.; 3 minutes to read +7; In this article. Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). The key must be kept secret from anyone who should not decrypt your data. ExpressJS and PassportJS Sessions Deep Dive. Table of Contents. ExpressJS & PassportJS 101. With the id from the cookie header, Express reads the session store and puts all the info onto req.session, which is available to you on each request. Express will generate sessions for requests on static files like stylesheets, images,. Creating CloudFront Key Pairs for Your Trusted Signers Each of the AWS accounts that you use to create CloudFront signed URLs or signed cookies—your trusted signers—must have its own CloudFront key pair, and the key pair must be active. Using keys allows you to change the secret used to generate signatures without immediately invalidating all the existing sessions. The idea is that you specify an array of keys (secrets). Only the first one would be used for generating the signatures but all the entries would be valid for checking an incoming signature on a cookie.
A shared access signature (SAS) provides secure delegated access to resources in your storage account without compromising the security of your data. With a SAS, you have granular control over how a client can access your data. You can control what resources the client may access, what permissions they have on those resources, and how long the SAS is valid, among other parameters.
Azure Storage supports three types of shared access signatures:
User delegation SAS. A user delegation SAS is secured with Azure Active Directory (Azure AD) credentials and also by the permissions specified for the SAS. A user delegation SAS applies to Blob storage only.
For more information about the user delegation SAS, see Create a user delegation SAS (REST API).
Service SAS. A service SAS is secured with the storage account key. A service SAS delegates access to a resource in only one of the Azure Storage services: Blob storage, Queue storage, Table storage, or Azure Files.
For more information about the service SAS, see Create a service SAS (REST API).
Account SAS. An account SAS is secured with the storage account key. An account SAS delegates access to resources in one or more of the storage services. All of the operations available via a service or user delegation SAS are also available via an account SAS. Additionally, with the account SAS, you can delegate access to operations that apply at the level of the service, such as Get/Set Service Properties and Get Service Stats operations. You can also delegate access to read, write, and delete operations on blob containers, tables, queues, and file shares that are not permitted with a service SAS.
For more information about the account SAS, Create an account SAS (REST API).
Note
Microsoft recommends that you use Azure AD credentials when possible as a security best practice, rather than using the account key, which can be more easily compromised. When your application design requires shared access signatures for access to Blob storage, use Azure AD credentials to create a user delegation SAS when possible for superior security.
A shared access signature can take one of two forms:
Note
A user delegation SAS or an account SAS must be an ad hoc SAS. Stored access policies are not supported for the user delegation SAS or the account SAS.
A shared access signature is a signed URI that points to one or more storage resources and includes a token that contains a special set of query parameters. The token indicates how the resources may be accessed by the client. One of the query parameters, the signature, is constructed from the SAS parameters and signed with the key that was used to create the SAS. This signature is used by Azure Storage to authorize access to the storage resource.
You can sign a SAS in one of two ways:
With a user delegation key that was created using Azure Active Directory (Azure AD) credentials. A user delegation SAS is signed with the user delegation key.
To get the user delegation key and create the SAS, an Azure AD security principal must be assigned a role-based access control (RBAC) role that includes the Microsoft.Storage/storageAccounts/blobServices/generateUserDelegationKey action. For detailed information about RBAC roles with permissions to get the user delegation key, see Create a user delegation SAS (REST API).
With the storage account key. Both a service SAS and an account SAS are signed with the storage account key. To create a SAS that is signed with the account key, an application must have access to the account key.
The SAS token is a string that you generate on the client side, for example by using one of the Azure Storage client libraries. The SAS token is not tracked by Azure Storage in any way. You can create an unlimited number of SAS tokens on the client side. After you create a SAS, you can distribute it to client applications that require access to resources in your storage account.
When a client application provides a SAS URI to Azure Storage as part of a request, the service checks the SAS parameters and signature to verify that it is valid for authorizing the request. If the service verifies that the signature is valid, then the request is authorized. Otherwise, the request is declined with error code 403 (Forbidden).
Here's an example of a service SAS URI, showing the resource URI and the SAS token:
Use a SAS when you want to provide secure access to resources in your storage account to any client who does not otherwise have permissions to those resources.
A common scenario where a SAS is useful is a service where users read and write their own data to your storage account. In a scenario where a storage account stores user data, there are two typical design patterns:
Clients upload and download data via a front-end proxy service, which performs authentication. This front-end proxy service has the advantage of allowing validation of business rules, but for large amounts of data or high-volume transactions, creating a service that can scale to match demand may be expensive or difficult.
A lightweight service authenticates the client as needed and then generates a SAS. Once the client application receives the SAS, they can access storage account resources directly with the permissions defined by the SAS and for the interval allowed by the SAS. The SAS mitigates the need for routing all data through the front-end proxy service.
Many real-world services may use a hybrid of these two approaches. For example, some data might be processed and validated via the front-end proxy, while other data is saved and/or read directly using SAS.
Additionally, a SAS is required to authorize access to the source object in a copy operation in certain scenarios:
When you use shared access signatures in your applications, you need to be aware of two potential risks:
The following recommendations for using shared access signatures can help mitigate these risks:
To get started with shared access signatures, see the following articles for each SAS type.
This article helps you create an ExpressRoute circuit using the Azure portal and the Azure Resource Manager deployment model. You can also check the status, update, delete, or deprovision a circuit.
From a browser, navigate to the Azure portal and sign in with your Azure account.
Important
Your ExpressRoute circuit is billed from the moment a service key is issued. Ensure that you perform this operation when the connectivity provider is ready to provision the circuit.
You can create an ExpressRoute circuit by selecting the option to create a new resource.
On the Azure portal menu or from the Home page, select Create a resource. Select Networking > ExpressRoute, as shown in the following image:
After you click ExpressRoute, you'll see the Create ExpressRoute circuit page. When you're filling in the values on this page, make sure that you specify the correct SKU tier (Standard, or Premium) and data metering billing model (Unlimited or Metered).
Tier determines whether an ExpressRoute standard or an ExpressRoute premium add-on is enabled. You can specify Standard to get the standard SKU or Premium for the premium add-on.
Data metering determines the billing type. You can specify Metered for a metered data plan and Unlimited for an unlimited data plan. Note that you can change the billing type from Metered to Unlimited.
Important
You can't change the type from Unlimited to Metered.
Peering Location is the physical location where you are peering with Microsoft.
Important
The Peering Location indicates the physical location where you are peering with Microsoft. This is not linked to 'Location' property, which refers to the geography where the Azure Network Resource Provider is located. While they are not related, it is a good practice to choose a Network Resource Provider geographically close to the Peering Location of the circuit.
View all the circuits
You can view all the circuits that you created by selecting All resources on the left-side menu.
View the properties
You can view the properties of the circuit by selecting it. On the Overview page for your circuit, the service key appears in the service key field. You must copy the service key for your circuit and pass it down to the service provider to complete the provisioning process. The circuit service key is specific to your circuit.
On this page, Provider status provides information on the current state of provisioning on the service-provider side. Circuit status provides the state on the Microsoft side. For more information about circuit provisioning states, see the Workflows article.
When you create a new ExpressRoute circuit, the circuit is in the following state:
Provider status: Not provisioned
Circuit status: Enabled
The circuit changes to the following state when the connectivity provider is in the process of enabling it for you:
Provider status: Provisioning
Circuit status: Enabled
For you to be able to use an ExpressRoute circuit, it must be in the following state:
Provider status: Provisioned
Circuit status: Enabled
You can view the properties of the circuit that you're interested in by selecting it. Check the Provider status and ensure that it has moved to Provisioned before you continue.
For step-by-step instructions, refer to the ExpressRoute circuit routing configuration article to create and modify circuit peerings.
Important
These instructions only apply to circuits that are created with service providers that offer layer 2 connectivity services. If you're using a service provider that offers managed layer 3 services (typically an IP VPN, like MPLS), your connectivity provider configures and manages routing for you.
Next, link a virtual network to your ExpressRoute circuit. Use the Linking virtual networks to ExpressRoute circuits article when you work with the Resource Manager deployment model.
You can view the status of a circuit by selecting it and viewing the Overview page.
You can modify certain properties of an ExpressRoute circuit without impacting connectivity. You can modify the bandwidth, SKU, billing model and allow classic operations on the Configuration page. For information on limits and limitations, see the ExpressRoute FAQ.
You can perform the following tasks with no downtime:
Enable or disable an ExpressRoute Premium add-on for your ExpressRoute circuit.
Increase the bandwidth of your ExpressRoute circuit, provided there is capacity available on the port.
Important
Downgrading the bandwidth of a circuit is not supported.
Change the metering plan from Metered Data to Unlimited Data.
Important
Changing the metering plan from Unlimited Data to Metered Data is not supported.
Parallels business desktop 13 activation key generator. You can enable and disable Allow Classic Operations.
Important
You may have to recreate the ExpressRoute circuit if there is inadequate capacity on the existing port. You cannot upgrade the circuit if there is no additional capacity available at that location.
Although you can seamlessly upgrade the bandwidth, you cannot reduce the bandwidth of an ExpressRoute circuit without disruption. Downgrading bandwidth requires you to deprovision the ExpressRoute circuit and then reprovision a new ExpressRoute circuit.
Disabling the Premium add-on operation can fail if you're using resources that are greater than what is permitted for the standard circuit.
To modify an ExpressRoute circuit, click Configuration.
You can delete your ExpressRoute circuit by selecting the delete icon. Note the following information:
After you create your circuit, continue with the following next steps:
