In the process of deploying a BizTalk solution, Visual Studio first builds the assemblies. The deployment process requires that each assembly is strongly signed. You can strongly sign your assemblies by associating the project with a strong name assembly key file. If you haven't already done so, before deploying a solution from Visual Studio, use the following procedure to generate a strong name assembly key file and assign it to each project in the solution.
Prerequisites
To configure a strong name assembly key file. Start Visual Studio Command Prompt. At the command prompt, from the folder where you want to store the key file, type the following command, and then press ENTER: sn /k filename.snk. Example: sn /k ErrorHandling.snk. A confirmation message, Key pair written to filename.snk, displays on the. Generating a Secure Shell (SSH) Public/Private Key Pair Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms. Apr 24, 2006 Sharing a Strong Name Key File Across Projects. For everyone wondering about previous versions of VS (and this is possible in 2005 as well), you can store the key pair that you create in VS in a store. It’s one of the options when you create the key (and can be done using sn.exe as well). Can you please tell me the sharing a strong. If your project refers to other assemblies via InternalsVisibleToAttribute or other means where a strong-name string is required, then it is not feasible to build the repository-sources with a temporary key. Doing so will change the public key references that are present in the strong-name strings and break the code. I am utilizing in one of my applications a DLL. In the setup instructions it is saying if I need to consume the components I must specify a value for the AssemblyKeyFile attribute in the AssemblyInfo file indicating the path to the file containing the key pair used to generate the strong name such as a KeyPair.dat file. Using a development environment that supports creating strong names, such as Visual Studio. Creating a cryptographic key pair using the Strong Name tool (Sn.exe) and assigning that key pair to the assembly using either a command-line compiler or the Assembly Linker (Al.exe). The Windows SDK provides both Sn.exe and Al.exe.
To perform the procedure in this topic, you must be logged on with an account that is a member of the BizTalk Server Administrator's group. In addition, your account must have Write permissions on the global assembly cache (GAC). The Administrators account on the local computer has this permission.
To configure a strong name assembly key file
Start Visual Studio Command Prompt.
At the command prompt, from the folder where you want to store the key file, type the following command, and then press ENTER:
sn /kfile_name.snk
Example: sn /k ErrorHandling.snk
A confirmation message, Key pair written to <file_name>.snk
,displays on the command line.In Visual Studio Solution Explorer, right-click the project and then click Properties.
Click the Signing tab and choose Browse in the Choose a strong name key file drop down box.
Browse to the key file and click it. Click Open, and then close the project properties.
Repeat steps 3 through 6 for each project in the solution that you want to deploy using this strong name assembly key file.

An SSH key is a form of authentication in the SSH protocol. It is similar to a password, but allows for authentication without entering in a password or any manual input. SSH keys generally speaking are more secure, and convenient than password authentication.
Command Line
If you currently have access to SSH on your server, you can generate SSH keys on the command line using the ssh-keygen utility which is installed by default on our servers. Run it on your server with no options, or arguments to generate a 2048-bit RSA key pair (which is plenty secure).
You will be prompted to select a file for the key pair. The default directory for SSH keys is ~/.ssh with the private key named id_rsa and the public key named id_rsa.pub. By using the default file names, the SSH client will be able to automatically locate the keys during authentication so it is strongly recommended to not change them. You can use the default by pressing the Enter key.
If /home/USER/.ssh/id_rsa or a key of the name you chose already exists, you will be prompted to overwrite the keys. If you do overwrite the existing keys, you will not be able to use them to authenticate anymore.
After you have selected the file for the key pair, you be will be prompted to enter a passphrase to encrypt private key file. Encrypting the private key with a passphrase is optional, but it will improve security the keys. If you enter a passphrase you will have to provide each it time you use the key. You can press the Enter key to not use a passphrase; we strongly recommend the use of a passphrase with SSH keys.
A public and private key will now be generated.
WHM
You can generate SSH key pairs for root in WHM >> Home Security Center >> Manage root's SSH Keys.
Click Generate a New Key to get started.
There are several fields on this page: Key Name, Key Password, Key Type, and Key Size.
The default Key Name is id_rsa. Keys are generated in /root/.ssh/ so the default key name would create a private key in /root/.ssh/id_rsa, and a public key in /root/.ssh/id_rsa.pub. Using the default name will allow SSH clients to automatically locate the keys so it is strongly recommend you use the default name (simply leave the field blank or fill it with id_rsa).
The Key Password encrypts the private key file using a password to add an extra layer of security. The password must be provided each time the key is used for authentication to decrypt the private key. The Password Strength field indicates how strong your password is. 0 indicates a very weak password, and 100 indicates a very strong password. Click Password Generator to have a strong password generated for you.
Key Type and Key Size are RSA and 2048 by default, and are secure enough for most purposes so these can be left alone.
Click Generate Key to generate the SSH key pair. WHM will then display the location of the key.
PuTTY
PuTTY is an open Windows SSH client. You will need to have the PuTTYgen utility installed to generate an SSH key pair. PuTTYgen is included in Windows installer on the Download PuTTY site, but you can download it separately if you installed PuTTY without its extra utilities. See Connect using Putty to a Linux Server to learn more about PuTTY.
Open PuTTYgen.
The Parameters at the bottom can be adjusted to affect how secure the key is, but the default options are plenty secure for most purposes.
If you're satisfied with the parameters, click Generate in Actions to generate the key pair.
You may be asked to 'generate some randomness by moving the mouse over the blank area' to generate the key. The randomness is used to generate your keys securely, and make it difficult to reproduce them.
Once the key is generated, you will see the public key in PuTTYgen.
The Key passphrase field sets a password used to decrypt the private the key. This field is optional, and the private key will not be encrypted if it is omitted.Using a passphrase increases the security of your SSH keys, and we strongly recommend setting one.
Be sure to save both the public and private keys on your local machine so they can be used by PuTTY for authentication in the future by clicking the Save public key and Save private key buttons.
If you don't use a passphrase, it will prompt you to confirm before allowing you to save the private key. The private key will be saved as a .ppk file. The public key isn't given an extension by default, but .pub is a common extension for public key files. It can be saved as a .txt file as well as the public key file only stores the public key in plain text.
Command Line
If you currently have access to SSH on your server, you can upload the key over the command line.
Retrieve the contents of the public key. If the key was created in the default location, this can be done by outputting the contents of ~/.ssh/id_rsa.pub.
The output will look similar to the following:
Open the (and create if it doesn't exist) ~/.ssh/authorized_keys file using a text editor such as nano, pico, or vim.
If you had to create the ~/.ssh/ directory, or the authorized_keys file, you need to verify the permissions are correct, or you won't be able to login.
Paste the public key at the bottom of the file, and then save and close the file.
Alternatively, you can append the public key to ~/.ssh/authorized_keys with a single command.
You can use the cat command if the public key is stored in a file.
If the public key is not stored as a file on the server, you can use the echo command.
Be sure to include the entire public key in quotes after echo.
Once the public key is added to the authorized_keys file, you should be able to login using your SSH keys.
WHM
You can import an existing SSH key for root in WHM >> Home Security Center >> Manage root's SSH Keys.
Click Import Key.
The next page has a few fields to fill in.
You need to name the SSH key in the Choose a name for this key field. The default key name is id_rsa. Using the default name will allow SSH clients to automatically locate the keys so it is strongly recommend you use the default name (simply leave the field blank or fill it with id_rsa).
If you are importing a PPK (PuTTYgen key) file, enter its password (if applicable) in the Private key passphrase text box.
Generate Key From Crt File
Paste the public key into the appropriate box, but do not paste the private key into the box; private keys should always remain on the servers that generated them.
Click Import.
WHM will display the name of the keys imported, and you should now be able to authenticate over SSH using the key.
Generate Strong Name Key File
The default name for SSH key pairs is id_rsa, and that name will allow an SSH client to locate the key automatically. When an SSH key pair doesn't use the default name, you will need to specify the name of key used.
