int PEM_write_bio_RSAPublicKey(BIO *bp, RSA *x); int PEM_write_bio_RSA_PUBKEY(BIO *bp, RSA *x); 뭐가 다를까? The RSAPublicKey functions process an RSA public key using an RSA structure. The public key is encoded using a PKCS#1 RSAPublicKey structure. The RSA_PUBKEY functions also process an RSA public key using an RSA structure. However, the public key is encoded using a SubjectPublicKeyInfo structur..
