KeyStore Problem
Hi,Friends
I want to dynmatically to get keystore.
however,
I always get an exception says:
java.io.IOException: DER input, Integer tag error
what my certificate file is: export from web browser tool->option->Certificates -> other People ->Export
and select DER encoded binary X.509.
Here is my source:
KeyStore keystore = KeyStore.getInstance( "PKCS12" );
keystore.load( new FileInputStream( "D:\\certificate\\509.cer" ), "changeit".toCharArray() );
Thanks in advanced
I am not sure that If I found the issue or not.
only want to post here and hope expert to give me more solution.
my certificate is created by Verisign free trial version.
I found it is not Pcks12 format. it is pcks7.
and I also came cross that some one said the Provider is BouncyCastle.
And I downloaded OpenSSL tool to convert format to pcks12:
>>E:\Program Files\GnuWin32\bin>openssl pkcs12 -export -passout pass:"mcontact" -in pkcs7.p7b -out mcontact.p12
>>Loading 'screen' into random state - done
>>unable to load private key
So I have changed my source like this:
KeyStore keystore = KeyStore.getInstance("PKCS12", Security.getProvider("BC"));
keystore.load(new FileInputStream("D:\\certificate\\new\\mcontact.cer"), "changeit".toCharArray());
However it still pop exception :
java.io.IOException: stream does not represent a PKCS12 key store
Please help me!
