I've been reading through the OpenSSL documentation, but I must be missing something...
I have a public key (base64 encoded) which looks something like this: MIICIjANBgkqhkiG9w0BAQEFA......U8CAwEAAQ== This is in a char buffer. I've tried this with/without the wrapping text of -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY-----. I then do the following 2 lines of code: BIO* bio = BIO_new_mem_buf((void*)pubkey, -1); RSA* x = PEM_read_bio_RSA_PUBKEY(bio, NULL, NULL, NULL); As I understand it, this should: 1) create a BIO wrapper around the char* pubkey source, and 2) read from this BIO pointer an RSA key. However, the RSA pointer is null, and when I check the errors coming out of the library it says: error:0906D06C:PEM routines:PEM_read_bio:no start line I assume that I've formed the BIO instance incorrectly...what should I do differently? -Zach On 03/31/2013 02:49 AM, Dave Thompson wrote: >> From: owner-openssl-us...@openssl.org On Behalf Of Felipe Blauth >> Sent: Friday, 29 March, 2013 16:36 >> To read the key from your header file you might want to use >> a memory BIO in conjunction with the PEM_read_bio_PUBKEY function >> or PEM_read_bio_RSAPublicKey ( I don't remember which one you should >> use, but this was answered in this list before).
