thanks steve. i got my code working.
actually, this is pretty easy. following is my final code. hopefully, this can
do a little bit help to those who wants to do the same thing.
note that char array skey is copy and paste from a pem file generated by using
the openssl genrsa -out key.pem 1024.
EVP_PKEY*pkey = NULL;
const char skey[] =
-BEGIN RSA PRIVATE KEY-

dear all:
i am trying to read the rsa key from the memory (rather than from a file).
here is what i did:
1. use the openssl genrsa -out key.pem 1024 to generate a rsa key in the
file key.pem.
2. copy and paste the key from the key.pem to my code.
3. use a mem bio to read the key from the memory.
my code to do this is like the following.
the call to PEM_ASN1_read_bio always return null. anybody has any idea or
similiar experience? thanks a lot

Well there aren't any line feeds (\n) in there so you the whole thing is being
incorrectly represented as a single line.
