I have a keystore file which be the keystore of the server.

I am trying to test ssl connectivity to that server with the program as given on

But I am getting a NoSuchAlgorithmException on the following line :


// Can someone please tell me what all possible values I can pass to the above method, and what can be the best possible value by looking at the output below.

When I print the details of the certificate :

D:\Yogesh>keytool -list -keystore abc.jks -v -storepass xyz

Keystore type: jks
Keystore provider: SUN

Your keystore contains 2 entries:

When I looked at file

the key manager was found to be IbmX509

and when I used this value, I was able to run the program.

You can also use the following


The file lies in C:\Program Files\Java\jdk1.6.0_21\jre\lib\security or which ever java you are using.

# Determines the default key and trust manager factory algorithms for
# the package.
