TroubleShooting
Keystore : public and private server certificates
* To convert cert and key certs to p12 :
``openssl pkcs12 -export -out server.p12 -inkey server.key -in server.crt``
Thus, you will have : ``String KEYSTORE_DEFAULT_TYPE = "PKCS12"``
* To convert your p12 (containing public and private cert) to jks :
You have to know your alias (name matching your cert entry), if you dont have it retrieve it with : ``keytool -v -list -storetype pkcs12 -keystore server.p12``
``keytool -importkeystore -srckeystore server.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore server.jks``
Thus, you will have : ``String KEYSTORE_DEFAULT_TYPE = "JKS"``
Trustore : should contain only CA certificates
convert ca cert to jks :
```keytool -import -alias ca -file ca.crt -keystore cacerts.jks -storepass 123456```
Thus, you will have : ``String TRUSTORE_DEFAULT_TYPE = "JKS"``
Bad certificate | Unknown CA errors
This could mean you didn't import your not-trusted-CA certificate into your browser.
The remote host closed the connection
Usually happen when your browser closed the connection before the end of SSL handshake. If you already added your CA to your browser dont worry.
Both Chrome and Firefox need to MANUALLY add the certificate (in a popup) so putting it in parameter menu don't change anything.
Just load your URL with "https" : https://127.0.0.1:8443 . Browser will prompt you to accept the certificates and it will probably solve your connection error.
CKR_DOMAIN_PARAMS_INVALID error using openjdk
With openjdk-6-jdk and openjdk-7-jdk, I encountered java.security bug described in https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1006776 triggering a ``CKR_DOMAIN_PARAMS_INVALID`` exception error. Solution was to edit java.security parameters in /etc/java-7-openjdk/security/java.security
I replaced that :
```
security.provider.9=sun.security.smartcardio.SunPCSC
security.provider.10=sun.security.pkcs11.SunPKCS11 ${java.home}/lib/security/nss.cfg
```
with that :
```
#security.provider.9=sun.security.smartcardio.SunPCSC
security.provider.9=sun.security.ec.SunEC
#security.provider.10=sun.security.pkcs11.SunPKCS11 ${java.home}/lib/security/nss.cfg
```
Browser tested
This has been tested on following browser :
* Chrome
* Chromium
* Firefox
Debugging SSL connection error
I recommmend using openssl command line tool to debug ssl connection :
``openssl s_client -connect 127.0.0.1:8443``
You can also use vm argument debugging java ssl implementation : ``-Djavax.net.debug=ssl``
Server-Client key/cert generation
Certs are in libwesocket-test/certs folder, you will find server,client and ca cert build with easy-rsa :
https://github.com/OpenVPN/easy-rsa
With last release of easy-rsa, you can build your own key with the following :
* ``./build-ca`` : generate a new CA for you
* ``./build-server-full myServer`` : will build for you public cert and private cert signed with CA for server
* ``./build-client-full myClient`` : will build for you public cert and private cert signed with CA for client
