Hi,

I am working on SAML assertion. I have a private key abc.pem. I want to read this file and sign the assertion. The code I found on the internet is what I have written. I might be wrong, but somehow I think this code is for generation private key from a public key, which is what I don't want. I already have a private key, alias and its password. I just want to read it from file and sign the assertion. You help would be greatly appreciated.

Thanks,
Vijay
