How to: Create a public-private key pair.; 2 minutes to read; In this article. To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe).

For added assurance when you use Azure Key Vault, you can import or generate a key in a hardware security module (HSM); the key will never leave the HSM boundary. This scenario often is referred to as bring your own key (BYOK). Key Vault uses the nCipher nShield family of HSMs (FIPS 140-2 Level 2 validated) to protect your keys.

I already tried this: 1. Aspnetregiis -pc 'MyKeys' -exp 2. Aspnetregiis -pc 'MachineKeys2' -exp can I retrieve those key container using aspnetregiis? Because in Crypto/RSA/MachineKeys, the files name just only random number. In case I forgot, what keys that I have ever made. Is it possible to retrieve it using aspnetregiis? I am using aspnetregiis.exe to Encrypt a connectionStrings on an ASP.Net application. The application in productions runs on a Web Farm I run the following command to create a RSA encryption key with the export option. Aspnetregiis -pc 'CustomKeys' -exp Then I encrypt my connectionStrings using.

Use the information in this article to help you plan for, generate, and transfer your own HSM-protected keys to use with Azure Key Vault.

Note

  1. If you can, disable password logins in your “sshdconfig” file (on the server) and use keys instead. In case you travel and can’t carry your laptop with you, just keep your private key on a USB stick and attach it to your physical keychain. Your server will be much safer this way. Generate Public/Private SSH Key Pair.
  2. Nov 24, 2008 You can use the global machine-generated RSA key, but this is relatively insecure since everyone on the server has access to this key. The only secure solution is to use your own RSA keys that only your website has permissions to. You can generate RSA keys using the aspnetregiis.exe tool that comes with the.NET framework.
  3. In Key Vault, generate a key (referred to as a Key Exchange Key (KEK)). The KEK must be an RSA-HSM key that has only the import key operation. Only Key Vault Premium SKU supports RSA-HSM keys. Download the KEK public key as a.pem file. Transfer the KEK public key to an offline computer that is connected to an on-premises HSM.
  4. Oct 22, 2014  When you create an RSA key container to protect configuration information for one or more applications, it is recommended that you restrict the access to the machine-level RSA key container using the Aspnetregiis.exe tool, with the -pa option to add access to the key for a particular identity and the -pr option to remove access to the key.

This functionality is not available for Azure China 21Vianet.

This import method is available only for supported HSMs.

Overview

Here's an overview of the process. Specific steps to complete are described later in the article.

  • In Key Vault, generate a key (referred to as a Key Exchange Key (KEK)). The KEK must be an RSA-HSM key that has only the import key operation. Only Key Vault Premium SKU supports RSA-HSM keys.
  • Download the KEK public key as a .pem file.
  • Transfer the KEK public key to an offline computer that is connected to an on-premises HSM.
  • In the offline computer, use the BYOK tool provided by your HSM vendor to create a BYOK file.
  • The target key is encrypted with a KEK, which stays encrypted until it is transferred to the Key Vault HSM. Only the encrypted version of your key leaves the on-premises HSM.
  • A KEK that's generated inside a Key Vault HSM is not exportable. HSMs enforce the rule that no clear version of a KEK exists outside a Key Vault HSM.
  • The KEK must be in the same key vault where the target key will be imported.
  • When the BYOK file is uploaded to Key Vault, a Key Vault HSM uses the KEK private key to decrypt the target key material and import it as an HSM key. This operation happens entirely inside a Key Vault HSM. The target key always remains in the HSM protection boundary.

Generate and transfer your key to the Key Vault HSM

To generate and transfer your key to a Key Vault HSM:

Using Aspnet_regiis To Generate Public Private Rsa Keys Download

Step 1: Generate a KEK

A KEK is an RSA key that's generated in a Key Vault HSM. The KEK is used to encrypt the key you want to import (the target key).

Using Aspnet_regiis To Generate Public Private Rsa Keys Without

The KEK must be:

  • An RSA-HSM key (2,048-bit; 3,072-bit; or 4,096-bit)
  • Generated in the same key vault where you intend to import the target key
  • Created with allowed key operations set to import

Note

The KEK must have 'import' as the only allowed key operation. 'import' is mutually exclusive with all other key operations.

Use the az keyvault key create command to create a KEK that has key operations set to import. Record the key identifier (kid) that's returned from the following command. (You will use the kid value in Step 3.)

Step 2: Download the KEK public key

Use az keyvault key download to download the KEK public key to a .pem file. The target key you import is encrypted by using the KEK public key.

Transfer the KEKforBYOK.publickey.pem file to your offline computer. You will need this file in the next step.

Step 3: Generate and prepare your key for transfer

Refer to your HSM vendor's documentation to download and install the BYOK tool. Follow instructions from your HSM vendor to generate a target key, and then create a key transfer package (a BYOK file). The BYOK tool will use the kid from Step 1 and the KEKforBYOK.publickey.pem file you downloaded in Step 2 to generate an encrypted target key in a BYOK file.

Transfer the BYOK file to your connected computer.

Note

Using Aspnet_regiis To Generate Public Private Rsa Keys Free

Importing RSA 1,024-bit keys is not supported. Currently, importing an Elliptic Curve (EC) key is not supported.

Known issue: Importing an RSA 4K target key from SafeNet Luna HSMs is only supported with firmware 7.4.0 or newer.

Step 4: Transfer your key to Azure Key Vault

To complete the key import, transfer the key transfer package (a BYOK file) from your disconnected computer to the internet-connected computer. Rsa key pair generation algorithm c++. Use the az keyvault key import command to upload the BYOK file to the Key Vault HSM.

If the upload is successful, Azure CLI displays the properties of the imported key.
