java sardine over ssl

i'm trying sardine to make a webdav client, but it doesn't connect to my https server. in the usageguide say this about ssl http://code.google.com/p/sardine/wiki/UsageGuide#SSL but i dont know how to provide my custom Http client with my keystore.

i get this error.

Exception in thread "main" javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

How can i set up?

Solution

Pretty simple example (for http://mydrive.net and Linux):

download cert from mydrive.net with OpenSSL
- openssl s_client -connect webdav.mydrive.ch:443 > mydrive.net.crt
remove all stuff except of between BEGIN and END (inclusive) in mydrive.net.crt file
generate a new keystore:
- keytool -genkey -alias dummy -keyalg RSA -keystore /etc/ssl/certs/java/yourKeyStore.jks -keysize 2048
- use a secure passphrase
- Remove unused generated certificate
  - keytool -delete -alias dummy -keystore /etc/ssl/certs/java/yourKeyStore.jks
Import cert from mydrive.net
- keytool -import -trustcacerts -alias mydrive.net -keystore /etc/ssl/certs/java/kyourKeyStore.jks -file ./mydrive.net.crt
Verify import:
- keytool -list -keystore /etc/ssl/certs/java/yourKeyStore.jks
add Java Parameter for keystore
- JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=/etc/ssl/certs/java/yourKeyStore.jks"
Restart JVM

Now you can use Sardine without overwrite or reimplement methods. Just use

Sardine sardine = SardineFactory.begin(username, password);
List<DavResource> resources = sardine.list("https://webdav.mydrive.ch/");

Tip: Make sure to use the correct cert. MyDrive has several certs for example
