Java and SSL - java security NoSuchAlgorithmException

Question

I ve built a Java program as a front end for a database on a server  and I m trying to use SSL to encrypt traffic between clients and the server   Here is the command I issued to create the server certificate   keytool -genkey -alias localhost -keyalg RSA -keypass kpass123 -storepass kpass123 -keystore keystore jks   Here is the relevant code   System setProperty  javax net ssl keyStore                       G  Data Android Project keystore jks     System setProperty  javax net ssl keyPassword    kpass123     SSLServerSocketFactory factory         SSLServerSocketFactory SSLServerSocketFactory getDefault     SSLServerSocket accessSocket         SSLServerSocket factory createServerSocket DB ACCESS PORT     When I try to run this  I catch this      java security NoSuchAlgorithmException  Error constructing implementation  algorithm  Default  provider  SunJSSE  class  com sun net ssl internal ssl DefaultSSLContextImpl    I ve also found that the  KeyPairGenerator  service has algorithms DIFFIEHELLMAN  DSA  RSA available to it  while  SSLContext  has algorithms SSL  TLS  SSLV3  DEFAULT  TLSV1   Do I need to find some way to install RSA into the SSLContext service   Am I even looking at the correct services   Should I not be using RSA   I m new to the whole SSL - Security - Certificates thing  and it just blows me away that each of these different services don t have the same algorithms when they are supposed to be accessing the same certificates

Try javax net ssl keyStorePassword instead of javax net ssl keyPassword  the latter isn t mentioned in the JSSE ref guide   The algorithms you mention should be there by default using the default security providers  NoSuchAlgorithmExceptions are often cause by other underlying exceptions  file not found  wrong password  wrong keystore type        It s useful to look at the full stack trace   You could also use -Djavax net debug ssl  or at least -Djavax net debug ssl keymanager  to get more debugging information  if the information in the stack trace isn t sufficient
