This memo describes a secure pre-shared key (PSK) authentication method for the Internet Key Exchange Protocol (IKE). It is resistant to dictionary attack and retains security even when used with weak pre-shared keys. This document defines an Experimental Protocol for the Internet community. RandomKeygen is a free mobile-friendly tool that offers randomly generated keys and passwords you can use to secure any application, service or device. KEY RandomKeygen - The Secure Password & Keygen Generator. The pre-shared key to be encrypted can be configured either as standard, under an ISAKMP key ring, in aggressive mode, or as the group password under an EzVPN server or client setup. This sample configuration details how to set up encryption of both existing and new pre-shared keys. A preshared key can only be configured if this option is set to L2TP IPSec VPN or Automatic. Click to select the Use preshared key for authentication check box. In the Key box, type the preshared key value. This value must match the preshared key value that is entered on.

Jan 16, 2019  An attacker could, however, use the pre-shared key to impersonate a VPN server. It could then eavesdrop on encrypted traffic, or even inject malicious data into the connection. Despite some largely theoretical issues, L2TP/IPsec is generally regarded as being secure if openly published pre-shared keys are not used. The Nonce's are combined with the Pre-Shared-Key to create a Seed value for generating secret keys. The relative part of the IKE RFC is here: 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.

How to Configure IKEv1 With Preshared Keys

The IKE implementation offers algorithms whose keys vary in length.The key length that you choose is determined by site security. In general,longer keys provide more security than shorter keys.

In this procedure, you generate keys in ASCII format.

These procedures use the system names enigma and partym.Substitute the names of your systems for the names enigma and partym.

Before You Begin

You must become an administrator who is assigned the Network IPsec Managementrights profile. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2.

Openssl create csr with extended key usage. I'm using openssl on Mac OS X 10.9 to generate a self-signed certificate for Windows Server Remote Desktop Services.Using the command below I can generate the certificate, openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout myserver.key -out myserver.crtHowever, I need to add an extended key usage string Server Authentication (1.3.6.1.5.5.7.3.1) and I can't figure out how to do it in the command above.I have tried using the openssl option -extfile with a file containing this, = default extendedKeyUsage = 1.3.6.1.5.5.7.3.1However, I get an error that '-extfile option is not found'. While openssl x509 uses -extfile, the command you are using, openssl req, needs -config to specify the configuration file.So, you might use a command like this: openssl req -x509 -config certconfig -extensions 'my server exts' -nodes -days 365 -newkey rsa:4096 -keyout myserver.key -out myserver.crtThe usual prompts for the distinguished name bits are defined in the default configuration file (which is probably /System/Library/OpenSSL/openssl.cnf on OS X), but this file is not processed when you use -config, so your configuration file must also include some DN bits. Thus, the above-referenced certconfig might look something like this: req prompt = nodistinguishedname = my dn my dn # The bare minimum is probably a commonNamecommonName = secure.example.comcountryName = XXlocalityName = Fun LandorganizationName = MyCo LLC LTD INC (d.b.a.

1. On each system, create an /etc/inet/ike/config file.

   You can use the /etc/inet/ike/config.sample as a template.

2. Enterrules and global parameters in the ike/config file oneach system.

   The rules and global parameters in this file shouldpermit the IPsec policy in the system's ipsecinit.conf fileto succeed. The following IKEv1 configuration examples work with the ipsecinit.conf examples in How to Secure Network Traffic Between Two Servers With IPsec.

   1. For example, modify the /etc/inet/ike/config fileon the enigma system:
   2. Modify the /etc/inet/ike/config file on the partym system:
3. On each system, verify the syntax of the file.
4. Put the preshared key in the /etc/inet/secret/ike.preshared file on each system.
   1. For example, on the enigma system, the ike.preshared file would appear similar to the following:
   2. On the partym system, the ike.preshared file would appear similar to the following:
5. Enable the IKEv1 service.

When IKEv1 administrators want to refresh the preshared key, they edit the files on the peer systems and restart the in.iked daemon.

First, on every system in the two subnets that uses the preshared key, the administratorchanges the preshared key entry.

Then, the administrator restarts the IKEv1 service on every system.
