Yes, and this is size of modulus, RSA_size simply
returns BN_num_bytes(rsa->n);

PEM_read_RSAPublicKey reads from PKCS#1 ASN1 structure public
part of RSA key (n,e).

Oh, you mean size of RSA key, try RSA_size();
(and yes - this is size of modulus)

Hi, Thanks for the suggestion Marek. As posted earlier, my requirement is to know the Private Key Type and its PEM Length. EVP_PKEY would give me the private key Type and not its PEM Length. How do i extract the PEM Length of the EVP_PKEY ?
Is there an API for getting the EVP_PKEY

Yes,

Try d2i_RSAPrivateKey_bio();
