how can i solve it?

thanks my all helpers..
i made new certificate.
some more details are under

}The line at at org.tockit.comunication.ServerThread.run(ServerThread.java:55) is marked with ERRRROOOOOORRRRR and serverThread cod is posted on the fisrt reply post.
All this code works in absence of SSL (regular sockets).
I have another question related to the SSLSockets in the method of the serverThread, will my SSLSockets in the serverThread´s methods work to comunicate with other servers as i try to do?
Thanks!

And this is a method like the ones i asked on #1, sorry about this but i cant post more than 7500 characters

Https Issue:SSLHandshakeException:Received fatal alert:bad_certificate

hi experts,
My scenario is Proxy to AS2. In AS2 receiver I have https protocol. I have put SSL Certificate(keystore) value.
Let say
View- x
Certificate name- cer
then I have given
TRUSTED\x\cer
in SSL Certificate(keystore) field of AS2 receiver channel.
Let me know weather it is correct.
Second field in Communication channel is "Private key for Client Authentication". I have kept it as blank.
I am getting an error in AS2 Receiver Channel saying:-
Message processing failed. Cause: javax.resource.ResourceException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate # , SEEBURGER AS2: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate #
My certificate has not expired yet.
Please help me in this matter.
Thanks

hi experts,
Please look into the below matter and help me to resolve it.

Hi all,
I have to connect with a server via mutual authentication. I have to received a server certificate and send my client certificate, which I have stored in cacerts.
This certificate is a class 3 certificate from verisign.

FTPSClient - SSL Received fatal alert: bad_record_mac

I am trying to connect to an out of network server using org.apache.commons.net.ftp.FTPSClient
and trying to upload a file.
The code works correctly when i execute it from localhost but throws the following exception from prod server.

                    return;

               ftp.enterLocalPassiveMode();
               ftp.login(username, password);
======================
Any suggestions why would it work from my localhost and not from the server.
Could it be a firewall issue or do i need to user a certificate?

The FTP server sent you an alert saying that it received a bad_record_MAC from you, i.e. the client.
So there is something wrong with the client you used when it failed, or the underlying version of JSSE. Are the versions of Java the same in both cases?

Client Auth failure:SSLException Received fatal alert: bad_certificate

Friends,
I have managed to establish a one -way https connection between the client and the tomcat-server by keeping the client-Authentication=false

The server's truststore doesn't trust or possibly even recognize the client's certificate which came from the client's keystore.

So next I want to set up my client. The professor said that it's fine to just give the clients all self-signed certs, so I ran:
keytool -genkey -alias client1 -keyalg RSA -keystore c1keystore -storepass client1 -keypass client1 -dname "o=jhu, cn=Client 1"
I assumed that I need to add the Thawte Root CA Cert to this keystore as well since I'm doing client authentication:
keytool -import -v -file ../server/thawtecert.txt -trustcacerts -keystore c1keystore -storepass client1
I start up the server, and then I attempt to connect with the client with these options:
-Djavax.net.ssl.trustStore=server/serverstore
-Djavax.net.ssl.keyStore=client/c1keystore
-Djavax.net.ssl.keyStorePassword=client1
Now when I attempt to connect to the server and write to the buffer, I get this error on the client side:
javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate
And this error on the server side:
javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: null cert chain
If I connect to the server with these options, I connect fine:
-Djavax.net.ssl.trustStore=server/serverstore
-Djavax.net.ssl.keyStore=server/serverstore
-Djavax.net.ssl.keyStorePassword=server
I assume this means that I have done something very wrong creating the client's keystore. Does anyone know how I'm supposed to create it?

Hi ,
Even i get the same error . Although ,I imported the contents of my self-signed certificate into the truststore of tomcat i.e.cacerts file of jre/lib/security (in tomcat) , I get the following error:-
Tomcat does not seem to accept the client's certitficate.
Also , Incase if i use a standalone Java application to connect to a tomcat application , I get the same error? Any idea as to how does tomcat server authenticate the client from a standalone Java application .

CA-Signed certificate: Received fatal alert: bad_certificate

Hello. I am still trying to get rmi ssl to work in the way I want (see my post http://forums.sun.com/thread.jspa?threadID=5351278&tstart=15 ).
I read that CA signed certificates are preferred to self signed certificates due to several reasons. Due to the fact, that I want to run a lot of different services, each with an own certificate, it is out of question to let them be signed by a real CA (for now all is in a testing environment and once I have solved all the problems this might become an option).
So for now, I create my own certificate authority and sign the certificates for my services (who interact with each other via ssl).
If there is a flaw in my setup, please tell me. If not continue reading.
In my scenario, a service A is querying a server S to discover a service B. S sends all the information about B back to A, including the certificate of B (so A can use ssl to talk to B). I use client authentication.
Each component uses a keystore, which acts as a truststore at the same time.
When I use self signed certificates and import them to the other keystores (using keytool) everything works as it should.
My setup using ca-signed certificates fails.
At the beginning the server has all the certificates in his keystore (A & B & S, which were signed with the servers secret key, who acts as my CA). A contains the servers certificate and his own, which has been signed with the servers private key (A &S). B contains the servers certificate and his own, which has been signed with the servers private key (B & S).
As far as I understand ssl, if A wants to talk to B, it needs the certificate of B (and needs to trust it).
In my scenario, A is receiving the certificate of B, when it queries the server for information about B. The certificate is imported into As keystore (works), but the method call fails with:
javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate
Is rmi ssl creating and using selfsigned certificates from the private keys in the keystore? Maybe I made a mistake, but I don't see it.
A has a certificate of B (and trusts it, because it was signed by an authority whose certificate is trusted from the beginning). B should trust the certificate of A (because it was signed by the same authority). So why is there a bad certificate?
My guess is, in the ssl handshake, A is using his private key to create a self signed certificate and is sending this to B. B has no reason of trusting a self-signed certificate and the handshake fails.
If you have any ideas, I appreciate them a lot.

Each component uses a keystore, which acts as a truststore at the same time.That's a really bad idea. They serve completely different purposes. Don't do that.Ok, I will change that. So the trust store is used for certificates I trust (which then can be used by ssl), the keystore is used to store secret keys or if I want to do "cryptography by hand".
As far as I understand ssl, if A wants to talk to B, it needs the certificate of B (and needs to trust it).That's true if B is a server. If A is the server in this scenario it is B that needs to trust A.
In my scenario, A is receiving the certificate of B, when it queries the server for information about B. The certificate is imported into As keystore (works)Should be truststoreI will change that it's only imported into the trust store (-> will do the separation of trust/key store).
but the method call fails with:
javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificateSo there is something wrong with the certificate that B sent.Yes, but I don't know why. I created a certificate signing request (csr) for B (using keytool) and then used openssl to create the certificate. When I use a private key and openssl to create a selfsigned certificate e.g. create csr for B, export private key of B, use openssl to create the certificate with the private key of B), it has the same checksum as a self signed certificate using keytool.
The trust store of B contains the CA signed certificate of B and the CA certificate. I don't understand why it is a "bad certificate".
Maybe separating key and trust store will solve the problem or give some new hints.
Is rmi ssl creating and using selfsigned certificates from the private keys in the keystore?No. SSL doesn't generate certificates at all. You do. SSL just looks in the keystore for a certificate to send that matches what the peer will accept, and sending that.
So maybe the CA cert is used for it, which would be fault. I'm going to check that.
A has a certificate of B (and trusts it, because it was signed by an authority whose certificate is trusted from the beginning). B should trust the certificate of A (because it was signed by the same authority).> A and B don't need mutual trust unless you have needClientAuth set 'true' somewhere, which you haven't mentioned.I mentioned it, but it came to my mind at the end of my post, so it's kind of hidden in the text. So, I do use client authentication.> > My guess is, in the ssl handshake, A is using his private key to create a self signed certificate> No. See above.> > and is sending this to B. B has no reason of trusting a self-signed certificate and the handshake fails.> No. There is something wrong with the certificate that was received by the side that first got the bad_certificate alert.Thanks a lot. I see several things clearer now.

SSLHandshakeException: Received fatal alert :handshake_failure

Hola forum,
I'm having a bit of a problem with ssl sockets currently. Please bear with me as this is my first run at using ssl sockets for anything and I've done a fair bit of searching on google already.
Here's the code I'm using:
(kindly ignore any typos as they are the result of having to manually type the code in - the code resides on a seperate system).
int port = 443;
String hostname = "hostname";
TrustManager[] trustAllCerts = new TrustManager[]{
   new X509TrustManager(){
      public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateExcpetion{}
      public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException{}
      public X509Certificate[] getAcceptedIssuers(){
          return new X509Certificate[0];
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, trustAllCerts, new SecureRandom());
SSLSocketFactory factory = sslContext.getSocketFactory();
SSLSocket socket = (SSLSocket)factory.getSocketFactory(hostname, port);
socket.setUseClientMode9true);
socket.startHandshake();
...this throws the following exception from startHandshake():
javax.net.ssl.SSLHandhakeException: Received fatal alert: handshake_failure

      at testcode.main(testcode.java 62)Any insight? I would be most appreciative. Thanks!

ejp thanks for the reply - unfortunately I have 0 control over the server that I am attempting to establish a connection to and I don't think I can get them to do much of anything (just getting their server certificate was some work).
Could this exception be caused by the server requiring client validation? I checked the various socket settings (forget the property names) but none of them indicated that client validation was required.
Let me know if just the debug on the client side would be helpful and I'll type it in.
--edit, alright here are what I think the relevant parts of the debugging info from the client side(bear with me as this has to be hand transcribed-). Please let me know if more is needed-

Why get "fatal alert: bad_certificate" but "certificate_expired"

Hi all,
I am testing 2 way SSL authentication now.
Expected Result:
When the client side provides a expired client cert to the server during handshaking, the server is supposed to return fatal alert: certificate_expired, which is exactly the client side wanna receive.
Acturally Result:
At first, I test server side with Tomcat, but the coming out result is that server will reject the connection with fatal alert: certificate_unknown.
Then, I try Weblogic. From Weblogic, I can see the warn:
<Nov 16, 2007 3:31:01 PM GMT+08:00>
<Warning><Security><BEA-090479>
<Certificate chain received from 206.225.50.35 - 206.225.50.35 failed date validity checks.>
But the client side will receive fatal alert : bad_certificate.
Any solution to get the expected response from server with fatal alert: certificate_expired?
Your help are appreciated!

WLS 10.3.3 (OSB) Exception faced : General runtime error: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received.

WLS 10.3.3 not supporting SHA2 cert at provider end . (wild card certificate cannot be imported to trusted certs)
During integration from OSB 11g we face below exception :
General runtime error: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received

Enable -Dssl.debug=true java option and capture the logs.

Getting error in OSB :: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received..

Hi There,
am getting error when invoking a webservice from OSB .
"The invocation resulted in an error: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received..".
certs were loaded to the trust store and could see certificates in Trust store.
surprisingly, same webservice works from SOA BPEL and even from soapUI.
I even made Host Name verification to NONE... none of those helped.
your suggestions are very much appreciated.
Thanks,
Karthik.

FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was receiv

I am trying to invoke a third part web-service (EDC RAVE) through the Oracle Service Bus/Weblogic Server. However whenever I try to use a business service to connect I get the following error message:
The invocation resulted in an error: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received..
I have tried to add the certificate to the set of trusted demo certificates but that doesn't seem to have solved the problem. Does anyone know how to resolve the problem?
The only solution I have found is:
http://download.oracle.com/docs/cd/E13222_01/wls/docs81/webserv/trouble.html#1071057
But I am using 10.3, not 8.1.

Hi,
I am getting the same error while invoking a Rave webservice from ALSB or from a web application hosted on weblogic 10.3.
I have tried first two of the options below, still got the same execption:
1) Disable host name verification ( never a pleasant thought )
2) Write your own custom hostname verification
3) Ask them to get a cert specific to their host ( with a CN of "someserver.mdsol.com, for instance ).
3rd one is not an option for us, as Medidata does not want to do any change in their setup or to obtain new certificate with CN specific to their host.
After troubleshooting for several days I am out of ideas. Would appreciate if someone helps me on this.
Some further details:
The Rave server presents a wildcard certificate with CN as *.mdsol.com. I have imported all the certificates in the chain to the trust store.
Configured the trust store in weblogic and disabled host name verification.
I have enabled the ssl debug, when i invoke Rave webservice, getting the following errors :

HELP received a FATAL ALERT

I've just did a sync on my palm I was adding an excel file and first it came up as a locked file. I removed said filed and attempted to add a modified version of this said file. (was told some formula's were not supported)
So after doing the second sync. I went to my documents on my Palm Tungsten E2 and now I get a black boxs
Fatal Alert
MemoryMgr.c,Line:3751, Free handle
I've done a few soft reset. And will remove said warning but the minute I try to go into the documents it freezes.
Even now I dd yet another sync to remove all the files I added today, and still get the same warning.
Post relates to: Tungsten E2

Are you sync'ing the excel file over to the handheld again? This may be causing the error.
The next step is to hard reset and rename the backup folder on your PC.
Go to http://www.palm.com/cgi-bin/cso_kbURL.cgi?ID=887 and follow the directions to do a hard reset. Next before you hotsync your data back over you will need to rename your backup folder, to do that go here;
XP
C:\program files\palm or palm one\[hotsync username]\ and rename your backup
folder to backup.old
Vista
Start-->documents\Palm OS Desktop\[hotsync username]\ and rename your backup
folder to backup.old
Then hotsync to your current hotsync name and all your contacts, calendar,
tasks, and memos will come back over.
Show file extensions for XP or Vista
XP
If you can not view file extensions on your PC I would like you to open a
folder go to Tools-->Folder Options--> View (tab) and under show hidden
files and folders uncheck hide file extensions for known file types.
Vista
Open control Panel go to Folder Options--> View (tab) and under show hidden
files and folders uncheck hide file extensions for known file types.
