Generate Pre Shared Key Vpn
For pre-shared keys: SKEYID = prf(pre-shared-key, Nib Nrb) SKEYID is the Seed value that will later be used to generate additional secret keys. The Pre-Shared-Key and both Nonce values (Nib is the Initiator's Nonce, and NrB is the Responder's Nonce) is combined by using a PRF, or Psuedo Random Function. IPsec Pre-Shared Key Generator 1) Create a list of at least 10 randomly generated passwords. 2) Over the phone, provide your VPN partner this website address and have them pick one. 3) Give your VPN partner a simple shorter password. 4) Both of you will click the Generate button.
Azure S2S VPN connection uses a pre-shared key (secret) to authenticate between your on-premises VPN device and the Azure VPN gateway. You can view and update the pre-shared key for a connection with Get-AzVirtualNetworkGatewayConnectionSharedKey and Set-AzVirtualNetworkGatewayConnectionSharedKey. Version 0.1 (02 May 2018) Prepare Pre-shared Keys In case Pre-shared Key will be used to authenticate IPSec tunnels, they need to be created on a Nodegrid system before they can be used. To create a Pre-Shared key on a Nodegrid use the below steps.
PSK Generator provides a secure process to negotiate a 64-byte IPsec Pre-Shared Key (also known as a Shared Secret or PSK) through insecure means, such as email.

By default, the script will generate random VPN credentials (pre-shared key, VPN username, and password) for you and display them at the end of the installation. However, if you want to use your own credentials, first you need to generate a strong password and PSK as shown. # openssl rand -base64 10 # openssl rand -base64 16. If you lose or forget this encryption key, you cannot restore the backup file. The encryption key must be at least 8 characters, and cannot be more than 15 characters. VPN pre-shared key. The pre-shared key is a passphrase used by two devices to encrypt and decrypt the data that goes through the tunnel. The two devices use the same passphrase.

Instructions:
You and your VPN partner will use two separate passwords to create a unique 64-byte shared secret with the help of a cryptographic hash generator. Regardless of the length of each password, the generated Shared Secret will always be 64 bytes.
1) Create a list of at least 10 randomly generated passwords. These passwords should be at least 64 characters long. Email the password list to your VPN partner, but do NOT include these instructions, this website address, or anything else in the email that reveals the process that is about to be used.
Hint: Click on the keyhole of the padlock picture above to get a list of 32 cryptographically strong random passwords.
2) Over the phone, provide your VPN partner this website address and have them pick one of the passwords from the list you emailed to them. Both of you will copy and paste the selected password to the Password Seed box.
3) Give your VPN partner a simple shorter password. Openssl generate seperate private key file. I suggest a 16-digit numeric string as this would be easy to share over the phone with a reduced chance of mistakes. Both of you will enter this shorter passsword in the Key box.
4) Both of you will click the Generate button. Verify the first and last 2 or 3 bytes over the phone to ensure you've created the same Shared Secret.
5) Copy and paste the Shared Secret to your VPN configuration.
Pre Shared Key Psk
Alternate Method: Both parties use a random password generator to create a list of 10 or more long passwords and email them to each other. On the phone, decide which password from one of the lists to use as the Password Seed and which password from the other list for the Key.
