Tnx for response and your patient. Returning on reading with read() may I ask you about comment header and footer? It's safe to jump lines of file pem starting with "-" or it's possible that the key contain the char "-" ? tnx

But nothing more elegant ? I do not think that in this case are more elegant solutions ... .... but you can try: You may create memory BIO: BIO *mem; if ((mem = BIO_new(BIO_s_mem())) == NULL) { goto err; } Write public key to this bio: if (PEM_write_bio_PUBKEY(mem, key) == 0) { BIO_free(mem); goto err; } and read to buffer in PEM format: if ((n = BIO_read(mem, buf, *len)) <= 0) { BIO_free(mem); goto err; } BIO_free(mem); This code is not tested nor checked, hope this helps.
