• cannot install self-signed certificates sbs2008 on Vista SP2 with IE8

  This patch really works on Vista SP2 with IE8 or do I have to change the registry and if so, this key is always the right pair?

• 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 :-/

  Cheers, Dom

  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

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

• RemoteAccess VPN to ASA 2 7.2 using self-signed certificate

  Dear friends,

  I need help or guide on how to install as State in the title.

  It is this configuration can be made? or the self-signed certificate cannot be used as VPN certificate.

  Unfortunately, we cannot deploy a dedicated CA server.

  But we cannot use as pre-shared key authentication because the configuration would force our ASA to disable the 'disable isakmp am-' which is unacceptable according to our independent auditor.

  So the best solution I can think of is to use the self-signed certificate that is suitable.

  Please advice me if there is somehow I can use 'isakmp am - disable' as well as the pre-shared key.

  Can I generate certificate using my ASA box? or I really need to use the dedicated CA server to make it work.

  This is a self-signed certificate of ASA, but I can't import into my Cisco VPN Client 5.0 it keep saying "error 39: impossible to import the certificate.

  SAB,

  You must have a separate server from CA to issue certificates for the client and register the ASA on the CA server.

  You cannot use the self-signed certificate on the SAA for the VPN client.

• Configure SSL for OUD 4444 port Admin port-&gt; replace the self signed certificates used

  Hi Experts,

  When installing OUD choose Certification self-signed for ports 1636 and 4444.

  Later I change the certificates used by the port of 1636 to a new key file containing the CA certificates. (Track the steps of: https://docs.oracle.com/cd/E52734_01/oud/OUDAG/security_clients_severs.htm#OUDAG00050)

  But same procedure does not have to replace the self signed certificates used by ports 4444!  Everyone is configured SSL (with Cert CA) on the Administration port?

  I couldn't even start the servers, you see an error:

  """

  The failure of the handshake could occur for various reasons:

  • Incompatible encryption suites in use by the client and the server. This would require the customer to use (or allow) a suite of encryption supported by the server.
  • Incompatible versions of SSL in use (the server can only accept TLS v1, while the client is capable of using SSL v3 only).
  • Incomplete trust for the certificate of the server path
  • The certificate is issued to another area.
  • incomplete certificate trust path between the certificate for the server, and a certification authority root.
  • In most cases, this is because the certificate is not present in the trust store

• self-signed certificates

  Can I continue to use free certificates signed during the reclassification of 5.1.2 to ekkuve 5.2? or do I have to use a certification authority?

  Even with view 5.1.x - self-signed certificates will not stop you to help visualize, but you will be able to see in custody in the client and in the administrator control panel. Best practice is to move to a certificate signed by a root of trust to get rid of these.

• 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?

• RTMPS with self-signed certificate

  Hello
  
  I have a simple Webcam movie, publish live video
  FMS 2.0.2 r51 dev under Debian 3.1r2 edition
  and then he plays in another video-window.
  
  It works very well and rtmp, rtmpt, but with rtmps I get
  the error "NetConnection.Connect.Failed".
  
  I have prepared a simple and all assembled test scenario
  info here: http://pref.dyndns.org:8080/live/live.html
  
  The certificate has been created by me in this way:
  openssl req - x 509 - days 365 - newkey rsa:1024.
  -self-signed - certificate.pem - keyout pub-sec-.pem
  
  And implement defaultRoot_/Adaptor.xml:
  "< name HostPort ="edge1"ctl_channel =": 19350 ">: 1935, 80,-443 < / HostPort >"
  ... jumped...
  /Home/afarber/certs/self-signed-certificate.PEM < SSLCertificateFile > < / SSLCertificateFile >

  I found the solution-

  There is a bug in the current Flash Player:
  If a pop-up window of dialogue for a reason any
  (as unknown CA or not is not host name)
  then the cert will be rejected even if you
  Click 'yes '.

  If you are generating a cert self-signed like this:

  OpenSSL genrsa-des3-out ca.key 4096
  openssl req - new - x 509 - days 365 - key ca.key - out ca.crt

  OpenSSL genrsa-des3-out server.key 4096
  openssl req - new - key server.key - out server.csr

  OpenSSL x 509 - req-days 365 - in server.csr - CA ca.crt - CAkey ca.key - set_serial 01 - out server.crt

  (increase the 01 above for each new cert).

  and then import the ca.crt from above in your
  browsers (i.e. double-click on Windows for IE
  Open from Mozilla Firefox and click OK).

• TLS fails on linux self-signed certificates

  on firefox 38.1.0 under centOS 6.6 I have some problem with TLS.

  When it first happened I re fact cert using keys of 2048 bytes. It seemed if address the issue when you navigate to similar addresses to https://localhost/somesite, however, I have try https://localhost:10000 with the fact that it still fails:

  An error occurred during a connection to localhost.localdomain:10000. The certificate server included a public key which was too low. (Error code: ssl_error_weak_server_cert_key)

     The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
     Please contact the website owners to inform them of this problem.
  

  The signing certificate is algorithim-> PKCS #1 SHA-1 with RSA encryption

  The algorithim public key is-> PKCS #1 RSA encryption

  The key has been creating 07/06/15 for a period of 10 years is a Version 1 cert issued by myself with the info
  E = [email protected]
  CN = localhost
  UO = hq
  O = permite

  It was a problem of webmin.

  To fix this /etc/webmin/miniserv.pem edition replace the cert and private key sections.

  Use a new generated key and self-signed certificate. If you follow the instructions of centOS, the location of the files are /etc/pki/tls/private/ca.key and /etc/pki/tls/certs/ca.crt

• 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.

• QNXStageWebView and self-signed certificates

  I use the QNXStageWebView control to load HTML pages in my AIR application. I'm testing with OS version 1.0.7.3133 and version 2.7 AIR and Tablet OS SDK 1.1.0.  When I use https and try to access a web site that uses a self-signed certificate (which is not approved on the device), the object of QNXStageWebView does not throw error events. How can I detect that the user tries to access a unreliable website and warn (as the native browser)? I saw the newspapers of Wireshark and I see an error "the handshake failed".

  Hello Kiran,

  After further investigation, the dialog box for the certificate that is popped up by the WebKit is made under the covers. The issue which is seen is actually a bug in sdk. However the bug has been fixed and the fix will be available in the next version of the blackberry Tablet sdk.

  Let me know if you have any questions, and I'll be happy to answer them for you.

• 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.
