The problem was actually my program(more complex than the test case) is

Hi list,
I need to get an X509 *cert using string buffer, which is a base64
encoded representation of it. In other words, if I have the contents of

I used d2i_X509_bio() function for

Thanks for the reply.
Yes I took that approach but it didn't work. That's why I dig a bit
further down and tried locate where exactly the error is. I figured that
new lines in the base64 encoded string buffer are necessary to cast a
certificate out of it. May be my observation is

I found another way to get this job done. And it is working on all the

Instead of using PEM_read_bio_PrivateKey() we used d2i_PrivateKey_bio().

I can decrypt the data that are encrypted by my application. (It's a

But it is not inter-operable with the WSS4J. WSS4J uses bouncy castle

Is it the unique key to identify a key/cert pair in a key store?
Besides there is no way to give such in the parse() function.
Giving the same password might appear as a rare case. But that doesn't
mean it'll never happen.
