What is the pre-shared key for VPN?
A pre-shared key is a Site-to-Site VPN tunnel option that you can specify when you create a Site-to-Site VPN tunnel. A pre-shared key is a string that you enter when you configure your customer gateway device.
What is IKE pre-shared key?
IKE peers authenticate each other by computing and sending a keyed hash of data that includes the pre-shared key. If the receiving peer is able to independently create the same hash using its pre-shared key, then it knows that both peers must share the same secret, thus authenticating the other peer.
How do I change my pre-shared key for VPN?
- Go to Configuration > VPN > General > Tunnel Group.
- Select the tunnel group that applies to the VPN tunnel you want to change the pre-shared key for, and click the Edit button.
- Select the IPSec tab.
- This tab includes the Pre-shared Key field.
- Enter the new pre-shared key.
- Click OK.
- Click Apply.
Is a pre-shared key the same as a password?
The WEP key or WPA/WPA2 preshared key/passphrase is not the same as the password for the access point. The password lets you access the access point settings. The WEP key or WPA/WPA2 preshared key/passphrase allows printers and computers to join your wireless network.
How long should a VPN pre-shared key be?
You can use a pre-shared key (also called a shared secret or PSK) to authenticate the Cloud VPN tunnel to your peer VPN gateway. As a security best practice, we recommend that you generate a strong 32-character pre-shared key.
At what protocol does IKE works?
IKE builds upon the Oakley protocol and ISAKMP. IKE uses X. 509 certificates for authentication ‒ either pre-shared or distributed using DNS (preferably with DNSSEC) ‒ and a Diffie–Hellman key exchange to set up a shared session secret from which cryptographic keys are derived.
Which is better OpenVPN or IKEv2?
Performance: In many cases IKEv2 is faster than OpenVPN since it is less CPU-intensive. There are, however, numerous variables that affect speed, so this may not apply in all use cases. From a performance standpoint with mobile users, IKEv2 may be the best option because it does well establishing a reconnection.

Is the pre-shared key the password?
A pre-shared key is basically just a shared secret or password that is used to authenticate an individual attempting to join a wireless network (no username or identification or than the key is required).
What is a common problem with using pre-shared keys?
One of the dangers of pre-shared keys is that they can be captured in a hashed format over the air, allowing an attacker to perform offline password attacks to try to guess the key.
How do I configure the IKEv1 encryption?
Configuration Steps ¶ 1 Define the Encryption Domain 2 Specify the Phase 1 Policy 3 Specify the Phase 2 Proposal 4 Define the connection profile 5 Configure the Crypto Map 6 Bind the Crypto Map to the appropriate interface 7 Enable IKEv1 on the appropriate interface
What is IPsec Pre-Shared Key Generator?
How does the shared secret work with a VPN?
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.
Does Ike need to use aggressive mode for remote authentication?
But: If one remote side has only a dynamic IP address, IKE must use the aggressive mode for its authentication. In this scenario, a hash from the PSK traverses the Internet. An attacker can do an offline brute-force attack against this hash.
