How do I install this self-signed SSL certificate?

I haven't been able to connect to the jabber server I've been using (phcn.de) for quite some time now, so I filed a bug report with mcabber. The friendly people there told me to install phcn.de's self-signed certificate, but I can't figure out for the life of me how to do that.
I know I can download something resembling a certificate using
$ gnutls-cli --print-cert -p 5223 phcn.de
Which does give me something to work with:
Resolving 'phcn.de'...
Connecting to '88.198.14.54:5223'...

Hi,
I recently found out a way how to install test or self-signed certificates and use it with S1SE.
See:
http://www.gtlib.cc.gatech.edu/pub/linux/docs/HOWTO/other-formats/html_single/SSL-Certificates-HOWTO.html
Follow the instructions there
1. Create CA
2. Create root ca certificate
Now install the root-ca-certificate in S1SE -> Security>Certificate Management and Install a "Trusted Certificate Authority".
Paste the contents of the file: cacert.pem into the message-text box.
Then restart the server. Now your CA-Cert should be visible in the Manage Certificates menu.
The next step is to send a certificate-request from S1SE to your e-mail-address.
The contents of the e-mail the server sends to you (certificate request) must be pasted into the file: newreq.pem.
Now just sign the Request:
CA.pl -sign
The last step is that you have to paste the contents of the file newcert.pem into the message-box of the Security>Certificate Management - now under the option Certificate for "This Server".
Then you have to reboot the server/instance again and it should work with your certificate.

Dominic

How do i install a self signed server certificate

After using the admin tool to generate a request CSR, how do I sign this myself for testing purposes so I can install it and therefore run using https?
I have keytool and certutil both available on the system.
My most recent solution was to cut and paste the request to www.thawte.com/cgi/server/test.exe and it would return a certificate that was good for 21 days. This however is not the solution I am looking for.
Thanks

Abandoning Self-Signed SSL Certificates?

Hello,
I'm working on remediation of some security flaws and have encountered a finding that calls out each of my domain-added workstations as having self signed SSL certificates. I'm not an expert on the subject, but I do know the following things:
1) An earlier finding lead to me disabling all forms of SSL on my servers and workstations
2) Workstations use certificates to identify themselves to other domain assets.
Now my servers all have their own certs signed by an outside authority. However, it would be a huge amount of work to go through the process for each and every workstation. So my questions are these:
1) Can I create a NON-SSL self signed cert for these machines to use?
2) How do I remove these current SSL certs without having to hover over each workstation?
Basically, what's the least effort to remove self-signed SSL certs and replace them with something more secure?
Thanks,
M.

What do you mean when you say that you've disabled all forms of SSL on your servers and workstations? SSL serves to provide secure communications for all of your domain operations, so disabling SSL, in general, would likely break your entire domain. If you're
using certificates on your workstations, then you're using certificate-based security (IPSec) in some manner.
Do you have AD CS or some other certificate signing authority/PKI in your environment? If not, you would have to pay a public provider (i.e. VeriSign) to provide certificates, and I can assure you that gets very expensive.
If you have Microsoft servers in your environment, you can install and use Certificate Services to provide an internal signing mechanism which can be managed through group policy. You can replace all of the workstation certificates with ones signed by your
internal certificate authority (CA,) and those will pass muster with any auditor provided the appropriate safeguards are put into place elsewhere in your environment.
Least effort for you would be to implement an internal CA, which admittedly isn't a low-effort endeavor, and have the CA assign individual certificates to all of your machines, users, and any other assets you need to protect. If your auditors are requiring
the removal of the self-signed certificates, you might find a way to script the removal of the certificates. In my experience, however, most auditors just want IPSec to be done with certificates that terminate somewhere other than the local workstation (i.e.
an internal CA).

IPhone LDAP contacts and Self signed SSL certificates

Hi,
I am using OpenLDAP with self signed SSL certificate, and i am unable to get SSL work with LDAP contacts on the IPhone (4.x). I have tried to add a CA cert with a server certificate for the LDAP server and downloaded it to the IPhone by web, it adds the CA, but even with it, it does not want to connect to the LDAP server with SSL enabled.
Does LDAP contacts should work by adding new CA ? if yes, what is the exact procedure to do it ? (maybe I used a wrong CA export format, or wrong SSL certificate encryption format ...)
can someone tell me how to do it ?
This is really anoying, since we have multiple iphones on the company.
Thanks for the help.

Hello, found your post. I realize it's been 6 months since you posted, but I have a solution for you since I have struggled with the same problem since 2009.
I discovered that when the iPhone is using LDAPS, it tries to bind with LDAPv2. After it binds, it speaks LDAPv3 like it is supposed to. Apparently this is a somewhat common practice since OpenLDAP includes an option for it.
You'll want to set the following option in OpenLDAP:
dn: cn=config
olcAllows: bind_v2
Walla! LDAPS works! (assuming you've correctly done all the certificate stuff). Took some deep reading through the debug logs to figure out this problem. Figured I'd share my answer with others.

HT5012 How can you add a self signed CA Certificate to iOS 8?

How Can I add a self signed CA Certificate to an iPad with iOS 8.1?

I don’t think that I can help you but I am very interested in your question. Perhaps you have seen information about a related problem…
https://discussions.apple.com/thread/6590335
One way to install the self-signed CA certificate is to export it to a .CER file, email it to the iOS 8 device, open the attachment and process it. My guess is that the certificate will be installed (check the resulting profile) but due to an iOS 8 bug it will be ineffective.
Or, you could send a signed email from the email account for the CA. Open the email on the iOS 8 device and process it.
I assume your goal is for certificates issued by the CA to be automatically trusted on the iOS 8 device. Good luck with that.
The method I used was to send a .CER file. The CA certificate showed up as a profile. However, I do not get automatic trusting of certificates issued by the CA.

E-Mail Setup fails with self-signed SSL certificat...

Hi, one of my e-mails is with a small provider who just moved the mail server to Imap and SSL. In Thunderbird, everything works fine, setup on my Nokia C-6-fails with an unspecific error message (and trows away the settings). I asked the provider, and it seems that the problem comes up because the Nokia e-mail application doesn't asked me if I want to accept the certificate but instead rejects it. Is there a workaround to this problem? Is there a way to setup the mail account without using the wizard? Or to take over the settings from Thunderbird? Or a way to put the certificate in the right place manually? In Opera mobile I have no trouble with self-signed SSL certificates. Thanks Cave

Any one around who can help? Self-Signed certificates are rather common, after all. I would be grateful cave

Mail.app: Self-Signed SSL Certificates

How can I make mail trust self signed mail certificates FOREVER? As it is now, I have to tell Mail.app to always trust the cert for each email account, every time I launch mail. Then it remembers to trust it until I quit mail, then I have to re-tell it all over again. This is bearable on my desktop but on my laptop, where I need SSL the most, I'm constantly logging in and out and rebooting, and it drives me crazy.
FYI it's my own server, running Mac OS X Server. And I'm not buying a certificate, it's the encryption I'm after

First, the certificate must match the name Incoming Mail Server that your clients are using. For example 'mail.acme.com'. So, when creating the self-signed certificate, the common name that you enter would be 'mail.acme.com'. If you don't do this, you will always be prompted about the certificate when you relaunch Apple mail.
Just for clarification, here is how you should trust the self-signed certificate on the Macs that are using Apple Mail:
1. When you get the prompt about the certificate, click the show certificate button.
2. Drag the icon of the Certificate on the left in the Show Certificate dialog box to the desktop. This will create a document on your desktop named 'mail.acme.com.cer'.
3. Double click the certificate on the desktop which will open an Add Certificate dialog box.
4. Depending on the version of Mac OS X that you are running, what you do next will vary a little.
Leopard
1. Click the drop down next to keychain and select System
2. Open Keychain Access (Applications/Utilities) if it is not already open
3. Click System on left hand side under Keychains
4. Locate the 'mail.acme.com' certificate on the right and double-click it to open it. (NOTE: I had to quit Keychain Access and reopen it before the certificate showed up under System for me for some odd reason)
5. Click the gray triangle next to Trust to expand the Trust section of the Certificate.
6. Select Always Trust from the drop down next to 'When using this certificate'
7. Close the certificate window and then quit out of Keychain Access
8. Click the continue button back in Apple Mail if the Certificate dialog is still present.
9. Quit out of Apple Mail and the relaunch it again. This time you should not see the certificate dialog alert.
Tiger
1. Click the drop down next to keychain and select X509Anchors
2. Open Keychain Access (Applications/Utilities) if it is not already open
3. Click System on left hand side under Keychains
4. Locate the 'mail.acme.com' certificate on the right and double-click it to open it.
5. Click the gray triangle next to Trust to expand the Trust section of the Certificate.
6. Select Always Trust Settings from the drop down next to 'When using this certificate'
7. Close the certificate window and then quit out of Keychain Access
8. Click the continue button back in Apple Mail if the Certificate dialog is still present.
9. Quit out of Apple Mail and the relaunch it again. This time you should not see the certificate dialog alert.
This worked for me. I hope this works for you too.

Extend self-signed SSL certificate beyond one year

Hi all,
How can I extend SSL Certificate created by Windows 2008 R2's Certificate Service beyond 1 year?
Thanks.

Hi,
For self-signed certificate, you can use IIS Manager to create new one. For more detailed steps, please refer to the below steps.
Create a Self-Signed Server Certificate in IIS 7
http://technet.microsoft.com/library/cc753127(WS.10)
If it’s a certificate issued by a CA, we just need to renew the certificate with the CA to extend the valid date.

Problem with importing and creating self signed SSL certificate

Mac Pro, 10.7.2 Server. Attempting to import or create a self signed certificate for use as ichat.domain.com to encrypt iChat service. Server is acutally called server.domain.com but has an alias of ichat.domain.com. I understand that this is probably not best practice but I would like to keep things this way since we have one server, run multiple services on it, but want to continue to connect to each service at SERVICE.domain.com. We have been using this type of mismatched certificate with success since 10.4 or so.
I am working through setup of 10.7 Server to replace our 10.6 server.
Tried upgrade of 10.6 to 10.7 installation. The installation made a mess of some services and our Open Directory, but did move the certificate over and allowed iChat service to function properly.
Clean install and setup of 10.7 Server. Exported self signed certificate, private key, and encryption password from 10.6 Server and functioning 10.7 upgraded Server.
On import or manual creation of certificate get the following error:
Error
Check your server's logs for more information. The error (code 5001) was: Expected SecKeychainItemImport to return a SecIdentityRef, but it did not
Log shows:
Dec 29 17:56:55 server servermgrd[498]: -[CertsRequestHandler(HelperAdditions) importP12Data:passphrase:error:]: importedItems = (
"<SecCertificate 0x7fcf6ed43c00 [0x7fff78d96f40]>"
I have tried importing and manually creating other certificates with a variety of names with success. I assume that there is something buried somewhere that is causing this particular one to be a problem. Other than manually removing any remnants of the certificate from /etc/certficates I do not have any ideas what to try. I am essentially ready to move this server to 10.7 except for this problem and would like to avoid a reinstall.
Suggestions?

Self signed SSL Certificates no longer work after upgrade to 37.0.1

I followed these two articles to create local self signed certificates and they have been working fine since February. Now with the update to 37.0.1 I get "Secure Connection Failed" while trying to access my local website through FireFox. IE and Google Chrome have no problem accessing the local site.
http://www.jayway.com/2014/09/03/creating-self-signed-certificates-with-makecert-exe-for-development/
http://www.jayway.com/2014/10/27/configure-iis-to-use-your-self-signed-certificates-with-your-application/
I have already deleted cert8.db, restarted FF, then re-imported the self signed certificates but get the same error. No other software has changed on this box except the automatic upgrade to FF 37.0.1.
The network setting is already set to use "No Proxy"
How do I fix this?
Windows 8.1 Pro
IIS 8

I have exactly the same problem. All servers and devices that use a self-signed certificate are not reachable anymore via FF37.0.1 after upgrade to FF 37.0.1.
Firefox prints:
"Secure Connection Failed
The connection to the server was reset while the page was loading.
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."
I'm not getting the chance to add an exception hence no access to the server anymore.
This is a severe problem, because all internally used Glassfish servers in our test environments run with self-signed certificates. As Firefox blocks access to them I cannot maintain my servers anymore.
I have the same problem with Chrome but not with IE - IE is the offers to add an exception but suffers the blank page problem when accessing Glassfish.
I tried to adjust the following values in the FF config:
security.tls.version.min = 0 ;default
deleted cert8.db and restarted FF
I'm really lost, kindly advise.

How do I trust a self-signed issuer certificate?

I created a self-signed CA cert using openssl, and imported it into Firefox, but when I select it in the Certificate Manager under “Your Certificates” and click “View…”, I see the message “Could not verify this certificate because the issuer is not trusted.”
https://www.dropbox.com/s/i38v78802ym9fug/Screenshot%202014-04-15%2010.49.14.png
When I visit the site that I set up with an SSL cert signed by that same self-signed CA cert, I get an untrusted connection warning with the following technical details: “staging.cakemade.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is not trusted. (Error code: sec_error_untrusted_issuer)”
https://www.dropbox.com/s/rvq00r0pdn99rd6/Screenshot%202014-04-15%2010.57.54.png
When I view the site certificate, it correctly identifies the issuer as the CA cert that I imported, but also displays the message “Could not verify this certificate because the issuer is not trusted.”
https://www.dropbox.com/s/b3no5pdhf9ddx5h/Screenshot%202014-04-15%2010.57.29.png
I am using Firefox Aurora, and apply updates daily. I am using the default settings for OCSP.
https://www.dropbox.com/s/in58viu3q6wkxvn/Screenshot%202014-04-15%2011.02.22.png
What do I need to do to get Firefox to trust the CA cert that I imported?

I'm assuming you've imported your CA cert underneath the 'Authorities' tab.
Restart FF after importing the cert.
I'd expect you're being prompted to set the trust level upon importing the cert. If not you can do that manually via the 'Edit Trust' button.
