these are the steps i did :
1- created a keypair.
2- downloaded the keypair and used puttygen to generate a private key
3-created a new instance using the orion-psb-image-R5.4 image for a context broker.
4-created a security group and added a rule that opened the ssh port
5- associated a floating ip to that image
6-tried to access the image from putty using the floating ip and the private key generated in step 2
putty gives me this error:
Disconnected : No supported authentication methods available (server sent:publickey).
I would like to know how to solve this issue and understand the reason for it.
update:
Screen shots:
1.loading the downloaded keypair into puttygen
2.the downloaded keypair file from fiware lab (keypair.pem) and the generated private key
3.entering the floating ip for the contextbroker instance
4.loading the generated private key to use during connection establishment
5.the error message when i try to connect
Seems to be a problem with key generation or Putty configuration. Unfortunatelly, the question post doesn't include enough detail to provide a more precices anser.
I'd suggest you to edit your question post to include full detail of each step you have done (even including screenshots as you go).
EDIT: use centos as user login instead of root

I have owncloud version 9.1.8 running on a synology. Now I installed onlyoffice on a local server with a self signed certificat. It is important to know, that the onlyoffice server is running locally in a network. So I cannot access the server like e.g. with lets encrypt, because I only have a local server name and not a public server name. Lets Encrypt therefore cannot verify the server. However if I want (and if you have a solution doing that), I can access the internet using the server.
Now i have the problem, that owncloud delivers me the following error message
"Error while downloading the document file to be converted."
when I want to save the url in the onlyoffice configuration in owncloud. I guess the problem is, that I am using a self signed certificat. Do you know what I can do? Google does not really help me.
"Error while downloading the document file to be converted."
means that DocumentServer cannot validate your storage's self-signed certificate (OC in your case)
There are 2 possible workarounds:
1) Change "rejectUnauthorized" to false in the /etc/onlyoffice/documentserver/default.json config file
2) Change the default Node.js CAstore:
Edit the files:
/etc/supervisor/conf.d/onlyoffice-documentserver-converter.conf
/etc/supervisor/conf.d/onlyoffice-documentserver-docservice.conf
Add a flag --use-openssl-ca to the parameters in this line
Then you need to add your certificate to the the default CA store and restart ONLYOFFICE services:
supervisorctl restart all
I am building a solution to store keys and encrypt\decrypt data using an HSM. I am using a network HSM manufactured by Thales. The thing I have noticed is that a key generated in client machine 1 is inaccessible in client machine 2. The key can only be used to encrypt\decrypt data in client machine 1. Is there any thing that needs to be changed in my implementation or is there something to be changed in net-HSM configuration to enable this. I am using PKCS11Iterop library for all the key management operations.
I am using token based OCS protection.
I suppose your client machine 1 has a new file in kmdata/local directory associated to the new key generated.
But your client machine 2 has not this file in his kmdata/local directory.
You have to find a way to share the kmdata/local directory, for instance, using NFS.
When I try to create a new openshift application in Eclipse, they show me this error:
The authenticity of host 'droptest-daasenv.rhcloud.com' can't be established . RSA key fingerprint is cf:ee:....:a7.
When I click next, they show this msg:
Could not clone the repository. Authentication failed.
Please make sure that you added your private key to the ssh preferences.
ssh://56a4d5fb7628e14ac3000081#droptest-daasenv.rhcloud.com/~/git/droptest.git/: Session.connect: java.io.IOException: End of IO Stream Read
Can you guys tell me what should I do?
I assume you already have a RH cloud account.
In this case you just need to configure yout SSH keys for OpenShift online:
http://tools.jboss.org/documentation/howto/openshift_configssh.html
A second option is: take a look at this page, where I put a 4-minutes (mute) video to show how to use JBossTools to connect to OpenShift Online:

I am trying to install a certificate on my local machine (Win Server 2003) with the X509Certificate2 class in a C# test console application. When I install the certificate with the following code, everything is fine:
var serviceRuntimeMachineCertificateStore = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
serviceRuntimeMachineCertificateStore.Open(OpenFlags.ReadWrite);
cert = new X509Certificate2(certificatePath);
serviceRuntimeMachineCertificateStore.Add(cert);
serviceRuntimeMachineCertificateStore.Close();
Problem is, that the private key of the certificate is not persisted, when installed without the X509KeyStorageFlags.PersistKeySet. So I tried to instanciate the certificate like this (the private key has no password, so I pass in an empty string):
var serviceRuntimeMachineCertificateStore = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
serviceRuntimeMachineCertificateStore.Open(OpenFlags.ReadWrite);
cert = new X509Certificate2(certificatePath, "", X509KeyStorageFlags.PersistKeySet);
serviceRuntimeMachineCertificateStore.Add(cert);
serviceRuntimeMachineCertificateStore.Close();
But trying to instanciate the certificate throws a System.Security.Cryptography.CryptographicException "Failed to load certificate: The specified network password is not correct.", even though the private key has no password.
If I import the certificate in the Microsoft Management Console without specifying a password it works great.
Does anybody know how to do this programmatically?
If you try to create an instance of X509Certificate2 with an empty password on Windows XP or Windows 2003, the "Failed to load certificate: The specified network password is not correct." exception will be thrown.
If you can, try to create a certificate with a password which is not empty. Then everything should be fine.
Hopefully this will help somebody (and to expand on uGeeen's answer:
User "S C" points out the following requirement for certificate passwords on Windows XP and Windows Server 2003.
0 < password.Length < 32
I have seen conflicting reports on whether 32 is allowed. I can confirm that I was using a 32 character password (an MD5 hash), and truncating it to 30 characters fixed the issue.
are you doing it from worker process or some other impersonated process? it may be just that the identity your process uses is initialized WITHOUT loading the identity user's profile, what seems to result with no access to the user's cerificate store.
i've had similar problem when loading a x509 cert with private keys from within ASP.Net/IIS proces, and turning on profile-loading for worker processed did the trick
In case anybody has a similar problem: I managed to install the certificate and persist the private key in another fashion. I found the WinHttpCertCfg command line tool that you can get from here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winhttp/http/winhttpcertcfg_exe__a_certificate_configuration_tool.asp
I then call this command line tool programmatically to install the certificate. This site gave me a hint on how to use it: weblogs.asp.net/hernandl/archive/2005/02/09/…

Upon installation of a client side certificate, I am getting the exception "Object contains only the public half of a key pair. A private key must also be provided". My application is a VC#.NET application running over an ASP.NET platform. The application also uses WSE 2.0 to import certificates into making SOAP requests.
Upon research, I've found that this exception is of type System.Security.Cryptography.CryptographicException.
I am pretty positive all my WSE settings are configured correctly, since I was able to find a similar certificate by subject-distinguished-name. Any ideas will be greatly appreciated.
I was recently having the same problem. I found one explanation here that worked for me. Specifically, the permissions for the private key. The full info is copied below.
There are a couple things that I would
look at first:
Do you have a private key for this certificate?
Have you given permission for youf application to access the private
key?
You can establish whether you have a
private key by viewing the certificate
through the Windows Certificate Store.
To get to this, follow these steps:
From the Windows Start menu, select Run.
Type mmc in the Open: field. Click OK
Select "Add/Remove Snap-in" from the File menu.
Click the Add button.
Select "Certificates" from the list of Available Standalone Snap-ins.
Click the Add button.
Select "Computer account." Click Next.
Select "Local Computer". Click Finish.
Click Close.
Click OK.
Expand the Certificates node under the Console Root and open the
Personal store.
Double-click the Certificate you're using. If you have a private
key, the dialog will display a message
at the bottom that says "You have a
private key that corresponds to this
certificate".
If you have a private key, then ensure
that your application has permission
to access the key:
Open Windows Explorer.
Navigate to the C:\Documents and Settings\All Users\Application
Data\Microsoft\Crypto\RSA\MachineKeys
folder.
Select the files containing the keys that the WSE will need to
retrieve.
From the File menu, select Properties.
On the Security tab, add the ASPNET account and select th e Full
Control option.
Notes:
1. Determining which key file in the MachineKeys folder is
associated with a certificate can be
difficult. One easy method is to note
the creation date and time when
creating a new certificate. When you
view the files in the MachineKeys
directory, check the Date Modified
field for the corresponding date and
time.
2. If you have configured your system to run under a different
account than ASPNET, use that account
when granting permissions to access
the certificate.
As per my experience it could be failing because of two reasons.
Check if your cert has private key available.
If that is .net application then check if you have given permission to cert to make sure your application has permission to access the cert. In my case adding the "iis_iusrs" and given read permission does work for me.
Thanks.
After encountering the same exception: System.Security.Cryptography.CryptographicException, Object contains only the public half of a key pair, I proofed an alternative, but less optimal solution.
Situation: Certificate / key look up worked great inside of Visual Studio IIS Express, but while the Web Application was running under the proper IIS service, I always received the 'Contains only public half of key pair' exception.
I used the WSE3 CertificateTool to locate the private key section on the filesystem and attempted at length to adjust the user permission settings to give the ASP user permissions as per the above answer.
My eventual fix, which was not pretty, was to create a new IIS Application Pool specific to my Web service code and set the user Identity the pool runs as the Local machine owner of the certificate + private key.
The final location I installed the certificate in was "Local Computer / Trusted People".
Using WSE3 CustomPolicyAssertion, C# .NET:
clientToken = X509TokenProvider.CreateToken(StoreLocation.LocalMachine,
StoreName.TrustedPeople, "soap.partnersite.com", X509FindType.FindBySubjectName);
After updating the App Pool Identity, no private key file overrides were necessary when changing the application pool owner.
