I am getting the error " SVN: SSLv3 SSLContext not available SVN: OPTIONS request failed on ('SVN URL') while trying to connect to SVN repository through RAD 7.5.
I am using web sphere 7.0.
I am able to remote desktop to the server and also can login using the URL directly.
Only problem is through RAD.
Can anyone please help.
Thanks
It seems that RAD 7.5 does not support modern TLS/SSL versions, and supports only SSL 3.0 or older. I think that your server does not enable SSL 3.0 for security reasons. SSL 3.0 is deprecated and not secure.

I have a IBM MQ manager with SSL enabled .I can connect with MQ explorer with SSL keystore.
But if i try with a standalone Java client and same keystore , I am not able to connect.
I can see error messages as No X.509 selected and unavailable authentication scheme messages in the ssl logs and client is sending a empty certificate.
Standalone Java client : uses IBM JDK , java full version JRE 1.8.0 IBM
Windows AMD 64 build 8.0.7.20 - pwa6480sr7fp20-20221020_01(SR7 FP20),
Cipher suite used in Java client:
SSL_ECHDE_RSA_WITH_AES_256_GCM_SHA384
IBM MQ explorer version 9.1 ,Internal JRE: java full version JRE 1.8.0
IBM Windows AMD 64 build 8.0.5.41 - pwa6480sr5fp41-20190919_01(SR5
FP41),
Cipher Suite on the Queue manager end ECHDE_RSA_AES_256_GCM_SHA384
Same keystore used on both.( keystore doesn't have password).
Can anyone suggest what would be the issue here?
During developing Android application I faced a problem with SSL connection in android lower than KIT KAT.
Application is using ch.boye.httpclientandroidlib to connect. When I tried to get httpConnection I'm getting error:
here was error during executing http request.
javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
In Android newest than KIT KAT everything works fine.
I'm trying to use solution sugested in here but i have a problem with casting types from ch.boye.httpclientandroidlib to apache elements in my current implemetations.
Is there any solution for using this library for android lower than KIT KAT?
I found a solution to this same issue here... using the class TlsSniSocketFactory (you'll have to also download IgnoreSSLTrustManager and SelfSignedTrustManager from the same "util" folder) and add it to your project.
Then register the new scheme on your SchemeRegistry object like so:
schemeRegistry.register(new Scheme("https", new TlsSniSocketFactory(), port));
My issue was my web service is set to use TLS 1.2 only.
Android devices running Android 4.4.4 and below do not automatically enable TLS 1.2 so you have to manually enable it (IMPORTANT * devices older than Android 4.1 cannot support TLS 1.2 at all, so this solution wont work for those older devices)
Late answer but hopefully helps someone
Cheers
I want to enable TLS1.2 on glassfish 3.1.2.2 (build 5) with JDK7, I know JDK7 enables TLSv1.2, TLSv1.1, TLSv1 (default) and SSLv3.
I have upgraded the JDK version to JDK7 from JDK6, i'm connecting to glassfish server via SOAPUI client ( SOAPUI enabled TLS1.2 by setting -Dsoapui.https.protocols=TLSv1.2) to test a webservice application.
Following error is returning from server.
ERROR:javax.net.ssl.SSLHandshakeException: Server chose TLSv1, but
that protocol version is not enabled or not supported by the client.
I'm confused why glassfish doesn't choose the latest TLS version (TLS1.2) for the handshake.
Also found a glassfish blog
(https://java.net/projects/glassfish/lists/users/archive/2012-07/message/85)
stating glassfish3.1.2 had issues running TLS1.2 with JDK1.7
Does anyone successfully connected to glassfish3 via TLS1.2?
WE are having a webstart application.
Currently it is running fine.
Our jnlp file has unsecure links ie) http://********
When i change this from http to https://********* we are getting ssl handshake error.
How to make this working.
I hope we should install the security certificate in the client machine but our system is vast sowe need to either download the certificate or skip the certifiate checking part while using https.
Currently we are in Java 6. We are going to Migrate our application to Java8
Can someone please suggest some solution.?
Thanks in advance.
My java version is 1.6 and connect to a server over ssl using axis 2 stub; all used to work fine. It seems like they did some upgrade (apache2.4) and the ssl handshake doesn't happen anymore. I receive javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake error. Just for testing purpose, I locally installed jdk 8 and tested it works fine. Is there any way to make this work using jdk1.6? It is not possible to upgrade jdk now.
It is hard to tell without more details but I guess that the server either requires a TLS version unsupported by JDK 6 (e.g. TLS 1.1 or TLS 1.2) or uses ciphers which are not supported by JDK 6 yet. Another option might be that the server needs SNI (server name indication) which is not supported by JDK 6. If the problem is any of these things you are unfortunately out of luck with JDK 6.
I suggest you check with SSLLabs to get more details about the problem. They show also compatibility information regarding various JDK versions.
You could try using a 3rd party JCE provider, Bouncy Castle comes into mind:
