Hello,
I am using openssl_0.9.6a.
Following code has been used to convert a PKCS 12 cert to PEM format. But I am getting
some memory leaks reported. The report is listed at the end also.
Anyone has any ideas? I ran the same piece of code through Purify, same leak
reported. From there, I can see that the leak is coming from PKCS12_parse(). Besides
freeing the PKCS12 object, what else do I need to free here after calling
PKCS12_parse()?
Thanks for any help,
Kate
Here is my code:
