It looks like "len" is uninitialized. I'm assuming you've populated the
"buf" structure with the DER-encoded key from your database. You'll
need to set "len" to be the length of the object retrieved from your
database. For example:
long len;
unsigned char buf[1024];
RSA* pub_key;
len = my_read_database(buf,sizeof(buf));
pub_key = d2i_RSAPublicKey(NULL,buf,len);

Thanks for the answer, but I've used d2i_RSAPublicKey() and the
application crashed with a segmentation fault. I'm using this piece of
code:
char buf[1024];
int len;
RSA *PubKey;
PubKey = d2i_RSAPublicKey(NULL, (const unsigned char **)&buf, len);
What's wrong?
Best regards,
Herbert

| d2i_RSAPrivateKey()
| d2i_RSAPublicKey()
