Is pubKey a valid pointer after PEM_read_bio_RSA_PUBKEY? If it is NULL there is an error in PEM data.

Hi all. I'm trying to use the OpenSSL crypto lib. I've generated a public/private RSA key pair. Then I wrote some code to try to encrypt an eight-byte random string. But it crashes in RSA_size(). Here's the code: BIO* bp = BIO_new_mem_buf(_publicKey, -1); // Create a new memory buffer BIO. RSA* pubKey = PEM_read_bio_RSA_PUBKEY(bp, 0, 0, 0); // And read the RSA key from it. BIO_free(bp); // Allocate a string to hold the encrypted result. unsigned char encryptedRandKey[RSA_size(pubKey)]; _pubKey is a null-terminated character string that contains the RSA public key in PEM format (including -----BEGIN and so forth). RSA_size() crashes with bad access. Removing BIO_free() didn't make any difference. I also just tried assigning the value of RSA_size() to an int, and it crashed. Any ideas here? Thanks! Gavin
