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). I don't have a test enviroment right now, but you should do something like this:
char key[] = "Your pem key goes here"; BIO *mem = BIO_new(BIO_s_mem()); BIO_puts(mem, key); EVP_PKEY* pkey=PEM_read_bio_PUBKEY(mem,NULL,NULL,NULL); ... 2013/3/29 Zach <lace...@roboticresearch.com> > The reason I want to put the public key into the header file is to > simply make it easier to use the software (you can do the public key > encryption of some data with only the binary file, not the binary and > another file).
