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.”

I am using Firefox Aurora, and apply updates daily. I am using the default settings for OCSP.

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.

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. -
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'...

Unfortunately, the above command spits out more than a certificate. Do I need the additional information? If so, what do I need it for? Where do I need to put the certificate file?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.

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.

Import and trust a self-signed CA certificate from the Terminal
Hello there,
i have a problem: I would like to import and trust a self-signed CA(root) certificate from the Terminal to the System.keychain.
My request is to create a installation script to install the Cisco AnyConnect VPN Client and the needed certificates.
For the import i have used the following command:
sudo security import certificate.cer -k "/Library/Keychain/System.keychain" -A
The Option "-A" says:
Allow any application to access the imported key without warning (insecure, not recommended!) <- From the Mac Developer Library
The command reportet: 1 certificate is importet ... but ... the certificate is not trusted.
What do i need to do to set this certificate as trustworthy at the terminal?
Thanks for your help and best regards
Benjamin
P.S. The command: sudo security add-trusted-cert -d -r trustRoot -k “/Library/Keychains/System.keychain” “/private/tmp/certs/certname.cer” doen't run, i get an error message. Found on http://derflounder.wordpress.com/2011/03/13/adding-new-trusted-root-certificates -to-system-keychain/Hello Linc Davis,
thanks for your answer and sorry for my mistake, because i had already changed the last argument but for this discussion i had only copy this example.
But your answer show me the right way, big thanks.
I had entred the following command (see the last argument):
sudo security add-trusted-cert -d -r trustRoot -k "/Library/Keychains/System.keychain" "~/Downloads/mycert.cer"
... and i get the following message:
***Error reading file ~/Downloads/mycert.cer

Today i changed the last argument to:
/Users/User/Downloads/mycert.cer
and its run.
Many thanks!

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 afterFirst, 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. -
OBIEE 11g SSL how to generate self-signed/demo certificate
Hi,
We are enabling SSL for OBIEE 11.1.1.5 environment and want to generate self-signed or demo certificate.
We are following note 1326781.1 and are at Step 1 - point 4 that says:
4. Submit the Certification request to your Signing Authority (CA).
Certification Authority(CA) is an valid signing authority of your choice (for example: OpenSSL, Verisign,
Microsoft, etc)
Upon submission of the certificate request, CA returns the certificate for the testmachine server (Server Certificate). Copy the CA certificate and Server Certificate to <MW_HOME>/SSL folder.

RV120W- How to create new unique self-signed certificate?
Hello,
how to create new unique self-signed certificate on RV120W? I can create request for singning by external CA, but I cannot create new unique self-signed certificate itself. Any idea? Did I miss something? Many thanks!
AbudefSo basically RV120W does not support self-signed certificate? It only allows to generate private key and certificate signin request. There is no chance to replace default generic ssl/vpn certifice within router itself? Could you please give me an advice, how to sign that request by some "CA"? I mean no commercial CA, I need something free running under Windows os. Many thanks!

How to generate self-signed CA certificate, client certifacate in pkcs12
Based on the requirement, i need to generate self-signed CA certificate, client certificate, keystore type all in PKCS12 format.
Below is the successful process of generating them in DER format
1. openssl req -x509 -newkey rsa:1024 -keyout cakey.pem -out cacert.pem -days 2190 -config openssl.cnf
2. keytool -genkey -alias client -keyalg RSA -keystore client-keystore.jks
3. keytool -certreq -keystore client-keystore.jks -storepass clientkeystore -alias client -file client.cert.req
4. openssl ca -config openssl.cnf -out client.pem -days 2190 -infiles client.cert.req
5. openssl x509 -outform DER -in client.pem -out client.cert
openssl x509 -outform DER -in cacert.pem -out cacert.cert
6. keytool -import -file cacert.cert -keystore client-keystore.jks -storepass clientkeystore -alias ca
keytool -import -file client.cert -keystore client-keystore.jks -storepass clientkeystore -alias client
So, i try to create them in PKCS12 format
1. openssl req -x509 -newkey rsa:1024 -keyout cakey.pem -out cacert.pem -days 2190 -config openssl.cnf
2. keytool -genkey -alias client -keyalg RSA -keystore client-keystore.jks -storetype pkcs12
3. keytool -certreq -keystore client-keystore.jks -storetype pkcs12 -storepass clientkeystore -alias client -file client.cert.req
4. openssl ca -config openssl.cnf -out client.pem -days 2190 -infiles client.cert.req
5. openssl pkcs12 -export -out cacert.p12 -in cacert.pem -inkey cakey.pem -name "CA Certificate"
cacert.p12 successfully created. but,
openssl pkcs12 -export -out client.p12 -in client.pem -inkey cakey.pem -name "Client Certificate"
error message said "No certificate matches private key"
I have no idea that which step goes wrong....any advice or suggestion? importantly is to convert into pkcs12 format.
ThanksYour last step should be to import the signed certificate back into your client PKCS#12 keystore, client-keystore.jks.
This file contains the private key used to create your signing requets originally, and must be matched when importing the signed certificate back in.
I think you will need to follow steps 5 & 6 in your DER example to complete the client PKCS12 keystore (including -storetype pkcs12 argument on the import statement).
Another way is to simply convert the keystore created in your DER example into a pkcs#12, by using JRE1.6 command:
keytool importkeystore -srckeystore [jks keystore] -srckeystoretype jks -destkeystore [pkcs12 keystore] -destkeystorestype pkcs12 -
EDirectory install - failed to retrieve self-signed root certificate:142
Hi,
My istallation has 2 NICs, public & internal.
My tree name is IS.
I have succesfully installed and used RedCarpet. I additionally enabled
the Firewall and DHCP server to allow internet access to my users.
On running Yast install for eDirectory I am given the default IP address
of the server, this is the Public IP address - I decided that eDirectory
was for internal use so changed IP address to internal one.
At 50% of installation an error pops up :-
Error
The installation failed to retrieve the self-signed root certificate:142
I aborted the installation.
I retried the install using the public Ip address, it complains ports are
already in use, I chose ignore and go ahead. Same error occurs :142.

Hi, this is roy.
had the same issue. using a supermicro with a builtin dual nic.
disabled it and installed an old pci nic to test and it finally loaded the
edirectory without an error.
on another note, i am installing the NLSBS 9.0 and had to manually load
the disk drivers since i have an adaptec 2010s raid adapter. i had
installed suse 9.3 on the same machine earlier with absolutely no issues,
but NLSBS is a pain. if you run red carpet and update all, then the driver
issue returns.
how do you get and install the service pack 2?
thanks,

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.

IOS 6.1 upgrade, self signed root certificate not working
Hello,
We have been deploying our organizations self signed root CA to the iPhones with Apple Configurator and using that to confirm the identity of our local webservers.
Has anyone had problems with self signed root certificates after upgrading to 6.1 (same with 6.1.1)?
Safari complains that "Safari cannot verify the identity of "<servername>", Activesync also stopped working.
Any ideas to overcome the issue, other than buying a hundred certs from a trusted ca?Same thing for me after updating to 6.1.2. Facebook, gmail, and many US govt sites certificates have been declared invalid by iOS/Safari. And there is no way to accept and continue, just click "ok" and you are forever prevented from those sites.

Nokia X - import self signed server certificate
Do someone know how to import a self signed server certificate? No CA root certificate, only a server!
I connect from all my devices to a Baikal server for calenders and addresses. For this machine I generate a self signed server certificate. I am working with all devices without problems after I import the certificate to this (iPhone, iPad, iMac, Win7, Srv2k8, Linux,...). Only the Nokia X don't want to accept it.
I store the cert in DER format and name ending to .cer to the memory card, choose the import, the cert is found and I have to name it, but then it will not import it??? And the CAdroid is not working?!
Do someone know how to do this right? Thanks.Hi, anoymo. You may install the self-signed certificate by downloading it using the phone's browser. The file format should be DER encoded binary (X.509). Or you can create an HTML file using the notepad. Just copy this code (<HTML><BODY><a href="FileName.cer">Install certificate</a></BODY></HTML>) excluding the parenthesis to the notepad and save it as .html. Create a zip file for the certificate and the HTML file, copy it to the phone then open the .html file it should prompt you to install the certificate. Directly importing it to the phone is not possible.

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.
