 +===== Certificates =====
 +Nice Introduction
 +https://developer.mozilla.org/en-US/docs/Introduction_to_Public-Key_Cryptography
  
 +==== Java ====
 +In Java Certificates are packed in Java Keystores.
 +
 +The can be exported from Java Keystore by doing. Details [[http://docs.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html|here]]:
 +<code> 
 +keytool  -exportcert {-alias alias} {-file cert_file} {-storetype storetype} {-keystore keystore} [-storepass storepass] {-providerName provider_name} {-providerClass provider_class_name {-providerArg provider_arg}} {-rfc} {-v} {-protected} {-Jjavaoption}
 +</code>
 +
 +
 +==== Android ====
 +The keystores which android do understand have do have the type BKS (Bouncycastle).
 +The bouncyCastel must have teh version bcprov-ext-jdk15on-1.46.jar, available here: http://repo1.maven.org/maven2/org/bouncycastle/bcprov-ext-jdk15on/1.46/bcprov-ext-jdk15on-1.46.jar
 +
 +The Android Keystoree can be creatd using Java's keytool as following:
 +
 +<code>
 +
 +REM Dieses Script generiert ein client-keystore, vom Typ BKS. Diese Keystores koennen von Android gelesen werden.
 +REM Das Script soll dazu verwendet werden Produktivzertifikate in einen Keystore zu packen und mit der App auszuliefern.
 +REM
 +REM Benutzung: die Zertifikate, welche im keystore gespeichert werden sollen ins gleiche Verzeichniss legen. Script ausfuhren. Der keystore client_keystore_bks.ks wird im gleichen Verzeichniss erzeugt.
