Create safer self-signed certificates on IOS router?

I use a router in 1921 and use partially as an AnyConnect (WebVPN) server for remote access in the location.  The certificate I used was a self-signed certificate & trustpoint generated on the router.  I am running as the last IOS available track to ensure that it has all the latest features.

Do a quick check of SSL against her of Qualys, he seems to have a lot of weaknesses and known vulnerabilities.

* Poodle TLS

* TLS 1.0 only

* SHA1

* Diffie-Hellman 1024 bits

* Some algorithms of older encryption which seem to be available (but I've never specified), as TLS RC4_128_MD5

The encryption mechanism and controls to create the cert don't give me much choice in the matter.

Is there a new or better way to create a more secure certificate chain on an IOS router?  I couldn't find the instructions anywhere.

Robert

Take a look at my guide to private networks virtual Suite-B.  It creates more secure certificates.  Note my comment about the minimum software version to use.

  • Create a self-signed certificate

    When I use ADM to access my router I always get a message that I have established a connection with "ip address", but the certificate belongs to IOS-self-signed-cert... etc. I generated RSA keys with the address. How to generate a new self-signed certificate that includes the ip address of the router? Thank you.

    You can use the "crypto pki trustpoint name" command on the router to create a self-signed certificate.

  • Creating a self signed certificate - how do you define the "storepass.

    Hi, I am trying to use ADT to create an AIR 2.7 file, but this is the first time I used the command line tool to build an and have problems to understand the process of signing.

    I can generate a keystore cert.p12 from the flash IDE, and it requires a password to the file (-storepass)

    I can also use ADT to create a certificate self-signed from the command line, you can specify here the - keystore (location cert) and - keypass (password for the key in the store)

    I can't find a way to generate a certificate self-signed, where you can specify the two passwords, one for the store (-storepass) and one for the key (-keypass).

    It is a problem because when I go to my file using ADT AIR package, it takes two passwords - storepass and - keypass seized may publish.

    Is anyone know how generate a .p12 self-signed certificate and have a control on the two keys...?

    I spent hours playing and research now so maybe the wrong end of the stick, could do with some help get beyond this issue.

    Thank you

  • Self-signed certificate

    Hi all

    How to create a self-signed certificate?

    Concerning
    CNU

    Hi ALAIN,

    You should use the utility orapki for this (to AS10g). 'Orapki' is a utility that is shipped along with the installation of the Oracle Application (path on windows $ORACLE_HOME/bin/orapki.bat) server and you can use the same to generate the wallet and certificate for your test object.

    Here are the steps, first of all, let's create an empty wallet and the other will add a self certificate signed to it.

    1 C:\Oracle10g\midtier2\bin\orapki.bat wallet create - portfolio. Eu1 - pwd
    2. Add C:\Oracle10g\midtier2\bin\orapki.bat wallet - wallet. -1024 key size - dn "CN = sample" - self_signed - pwd eu1 - validity 365

    Kind regards

  • Can I generate self-signed certificates free for Nexus 9 K?

    Hi, I have 22 9Ks Nexus that I just upgraded to 3,0000 I4 so I can use the REST API.

    I use vRealize Orchestrator for automation, and I can't access the REST API on the Orchestrator help link, as certificates are at expiration.

    I can't find much information on this subject for the 9 K, unless the 9Ks are mode of the AIT, in this case I think that TACS are the only people who can generate a certificate.

    Does anyone know otherwise work around this? Otherwise, I'll have to approach a TAC case for 22 certificates generated :-/

    I'm not familiar with the technology with what you're trying to integrate, but here's a guide on how generate a custom SSC (self-signed Cert) on a device:
    #conf t
    #hostname DEVICE01-NOTE: must not be changed
    #ip - domain test.local

    generate a General key label SSC_KEY module 2048 rsa key #crypto

    #crypto pki trustpoint SSC_LOCAL
    #subject - name, CN = DEVICE, DC = test, DC = local
    #enrollment selfsigned
    # crl revocation checking
    #rsakeypair SSC_KEY 2048

    #crypto ca enroll COMMAND SSC_LOCAL HIDDEN: initiate the creation of SSC

    % Include the serial number of the router in the name of the topic? [Yes/No]: no
    % Include an IP address in the name of the topic? [None]:
    % Generate self signed certificate router? [Yes/No]: Yes

    Router self-signed certificate created successfully

    After this make sure that you do NOT change the host name of the device :)

  • Self-signed certificates Z10 blackBerry

    I try to lateral load of the self-signed certificates on the device for testing of the reasons (see various other misfortunes listed elsewhere).  Settings > Security > certificates he seems to have the ability to do.  I can't find any documentation as to where certificates must be located to be detected.

    Some research on Google mentioned something about the process in which concerns the PlayBook, but that requires that they be placed in the Cert folder on the device.  The Z10 is not this standard file and it is not possible (AFAIK) to create this folder at the root of the device.

    Thank you

    The Z10 has the same Cert folder in the same location as the PlayBook, and the installation of a certificate process is the same, so documentation on who should serve you well.

    The folder is visible through network sharing, when you turn on sharing in the settings and display from a PC on your network... in case it wasn't clear.

  • How can I make a self-signed certificate trusted root CA?

    Hi all

    I created a certificate self-signed using IIS 7 and he attributed to my local Web site. Looks like my connection to my local server is encrypted; but the problem is that the indicators of certificate in all browsers are red and read the following error message:
    "The identity of the server to which you are connected can not be fully validated. You are connected to a server using a name that is valid only within your network, which has an external certification authority has no way to validate ownership of. Some certification authorities will issue certificates of these names without worrying, not no way to ensure that you are connected to the expected site and not a pirate. »
    What does this error mean? Why isn't this error get away when I add my certificate in "Authorities roots of trust certificate" in the MMC > certificates? I want to get a green light for my certificate in my browser! Is this possible?
    Thanks in advance.

    There is no way to convert a self-signed certificate in a certificate signed by a root CA.  In addition, simply by adding a certificate in a particular area of the crypto shop does not change its abililties.  The trust root certification authorities certificates must be issued by approved certification.  Add your own cert to the store zone does not trust.

  • Faced with Windows 2008 R2 PKI, self-signed certificates &amp; view iPad customer Secure Authentication to view connection server: UGH!

    Background: I was instructed to create a VMware View isolated laboratory test so that HIGHER-UPS can see how they could access the VM dedicated as well as how their developers could put related clones on-the-fly. The project was successful! Yay!

    Addendum: A boss wants to see how VMware View works when accessing his computer virtual dedicated via his iPad on the internet... And who needs a secure SSL connection.

    The problem is: the domain name I chose casually because the lab did not belong to me... So I can't have a real certificate from a trusted commercial certification authority.

    So I'll try to roll my own public Windows 2008 R2 PKI and... All that forcing the iPad to use DC/DNS server in the lab... Get only the single get iPad trust view connection server by importing a sort of certificate.

    Can I export/import a certificate of the CA of DC to the iPad via an attachment... And it happens with confidence. But how to create a login to view the server certificate and electronic-mail/import in the iPad so it happens with confidence? Whenever I try to export the certificate of the certificate of the view connection server store, send it to the iPad and install... The connection server certificate appears as 'not reliable' and the VMware View client will not connect.

    (Of course, I could get sloppy and set the iPad Client to accept untrusted connections... "But I want to solve the problem of approved connection).

    I could be missing something royally on the self-signed certificates and certificate chains.

    (It is a first for me dealing with Active Directory Windows Certificate Services. In the past, I always just installed expensive commercial SSL CA certificates in the certificates Windows Server stores before.)

    Any help or direction, you can provide would be appreciated. I'm rather confused.

    See you soon!

    Hello

    Maybe was your initial problem that the provided certificate must be a descendant of a trusted root, such as Verisign cert or

    the root certificate must be installed and all the intermediate certificates in the trust chain down to the one you use?

  • WPA2 Enterprise signed vs self-signed certificate

    Hello

    What are the risks by using a self-signed certificate on an OS X Server RADIUS client using WPA2-Enterprise?

    The biggest risk is teaching your users to ignore certificate warnings.  But tell all to ignore your warnings cert will be likely to train people to ignore all the warnings, possibly opening security threats.  For non-technical users, it's a bad habit to enforce.

    The cost of a valid certificate is not terrible.  If you have decided to build a wireless infrastructure secure by using certificates and RADIUS, buy a real certificate.  I hope this helps.
