title: PKCS#1 and PKCS#8 format for RSA private key
body: <p>Can some one help me understand how an RSA key literally is stored in these formats? I would like to know the difference between the PKCS formats vs Encodings(DER, PEM). From what I understand PEM is more human readable. Is PEM/DER for keys/certs similar to UTF-8/16 for characters? What is the significance of DER/PEM? Sorry too many questions but fed up googling and getting vague answers. Thanks.</p>
